How to fix macOS 10.15 Catalina problems

Hello, thrill seekers. Looks like you’ve installed macOS Catalina knowing it’s not perfect and despite all warnings ended up here. You are not alone. We’ve rummaged through the internet and collected all macOS Catalina issues known to date. And boy, there’s a lot of wrongs to fix.

Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share. Launch Parallels Desktop. From the File menu, choose New to open the Installation Assistant. In this post, we’ll install macOS Catalina on VMware on Windows PC. For this procedure, we’ll also need VMware Unlocker Patch Tool for macOS or macOS VMware Unlocker Patch Tool, so we’ve provided this and also installed it in this tutorial.In a significant event of Apple’s yearly developer conference which started yesterday, the keynote was chock-full of announcements, demos, and some. Music, TV, and podcasts take center stage. ITunes forever changed the way people experienced.

1. Can’t install macOS Catalina

You’ve unpacked the installer and now macOS Catalina install stuck on the initial reboot. All you can see is a black screen and even a hard reboot doesn’t help it. Though it’s perfectly normal for an installation to take some time (sometimes up to 10 hours), you can try a few workarounds.

• Install Catalina in the Safe Mode

1. Press and hold down the Power key to shut down your computer.
   
2. Now, hold down Shift while it’s booting up.
   You will see the Apple logo on a grayish background with a progress bar. After you entered the Safe mode, run the Catalina installer again. Hopefully, it reaches completion this time.

Tip: Press Command + L in the middle of the macOS installation. You will see if it’s still active and the remaining time before completion.

• Do a PRAM and SMC Reset

It’s one of those last-ditch solutions that restore deep system settings including kernel information. It isn’t something you should be doing regularly but in our case, it’s worth trying.

How to reset PRAM
1.Shut down your computer
2. Press the Power key
3. Immediately press Command + Option + P + R keys
4. Hold down the keys until your Mac reboots
5. Let go of the keys

To reset SMC

1. Turn off your Mac
2. Hold down Control + Shift + Option and press power
3. Hold the buttons for 10-15 sec
4. Release the keys and restart your Mac
After you’re done, repeat macOS Catalina installation from scratch.

• Free up space on your drive

macOS Catalina takes up about 30 GB on your drive. That’s unprecedented in macOS history. When you see the 'macOS Catalina cannot be installed on Macintosh HD' message, this sometimes means that there is not enough disk space for the new macOS. Therefore, you need to free up some space on your Mac.
How to free up space? Move your largest files onto an external drive — will take you about 20 minutes. Or if it looks like too much fuss, free up your storage with CleanMyMac X. It’s a tool that is actually notarized by Apple (shouldn’t be confused with MacKeeper).

You’ll easily remove 7-10 GBs of system garbage. Then you can install macOS Catalina on a drive that’s clean and refreshed.

Here I’ve found a link to a free version of this app — enjoy.

Catalina installation stuck on “Setting up your Mac” screen

So your installation has started but seems to be stuck on the initial screen. What can you do? If your patience has finally run out, it’s time for a mission abort.

1. Press the power button and wait till your Mac reboots.
2. Start the installation all over again — this time it should go fine.

“macOS Catalina could not be verified”

This error usually appears when the download has finished. Apparently, it has something to do with cached content associated with your user account.

1. Open System Preferences > Sharing > Content caching
2. Switch to “All content`’ in the dropdown menu

The first attempt to download Catalina would often return the same error. But don’t give up just yet! Try downloading Catalina once again — this time it will download it from the cached copy on your Mac which will take about 10-15 seconds. Now it should be ok.

If it doesn’t help you can also:

• Simply restart your Mac
• Download Catalina under different “user” on your Mac
  
• Try to delete system cache with CleanMyMac

2. macOS Catalina freezing upon reboot

The situation looks like this: macOS Catalina has completed the install, and after you restart your Mac it is stuck on login screen. You see the progress bar but it isn’t going anywhere. What to do?
As one user pointed out, the problem may be caused by 3d party kernel extensions or kexts. They act as drivers — if you like a Windows analogy — and give access to your Mac’s hardware.

• Solution: Move Library Extensions

As a band-aid solution, you can relocate your /Library/Extensions kexts to a backup folder. As confirmed by many users, this fixes macOS Catalina stuck on reboot problem.
To perform this, you will need Terminal app:
Click Launchpad > Terminal
Now paste in the following command:

mkdir ~/Extensions-Backup && sudo mv /Library/Extensions/* ~/Extensions-Backup/

This command relocates your Library Extensions to the username/Extensions Backup folder. Later you can put the Extensions back where they belong at: /Library/Extensions.

One more solution to macOS Catalina freezing

Generally, Macs freeze when some process is hogging the memory. Some background plugin could be eating up all the available RAM. Here is the method I use to identify my background memory-hoggers.
To get a clear idea what it is, I use CleanMyMac X’s Speed utility.
You need to install CleanMyMac X — it’s available as a free version too.
Open the app, click “Optimization.”

This will give you an idea what Launch Agents are working in the background so you can isolate and disable them.

PS. Heavy consumers — this tab reveals processes that are critically memory-demanding.

3. macOS Catalina apps not working

This is one of the macOS Catalina problems that trails back to macOS Mojave. As you’ve probably heard, app architecture knows 2 types: 32-bit and 64-bit. The 32-bit apps will not be supported on macOS Catalina, period. Sadly, they are not just some lo-fi indie apps, we are talking Photoshop!

Did you know:Apple states that 64-bit apps use memory more effectively and so will work faster on your Mac.

• Check your 32-bit apps

There’s a quick way to count your potentially problematic applications.

1. Click the Apple logo > About this Mac > System report
2. Now find Applications in the sidebar.

Not Able To Download Macos Catalina

To have a deeper look into your apps, where they come from, and how much space they are taking, run the Uninstaller tool in CleanMyMac X. Download this program here — it’s free to download.
Launch the app and click the Uninstaller tab

Here you can see your 32-bit apps and sort apps by “Last used.”

For example, I found a 32-bit video editor, which I didn’t realize was there, stealing away 600 MB of my space.

• Reset an app that misbehaves

If a particular app stopped working on macOS Catalina, you can reset it with CleanMyMac. This operation doesn’t delete any user data and only restores it to the default state. In 9 out of 10 cases this helps solve syncing issues and sudden app freeze-ups.

Choose an app from the list in the Uninstaller (see screenshot above)
Now click on the drop-down menu under “Uninstall” button
Click on the Reset button that appears

• Update your applications

In anticipation of various macOS Catalina issues, some developers have already optimized their programs for the new OS. Go to the developer’s site and download the latest available version.
Yes, I’ve already told you about CleanMyMac, but it appears to have just the right tool to handle macOS updates. It automatically updates every single app on your Mac. Though it may take some time, it’s a smart way to debug your macOS Catalina apps.
Once you get CleanMyMac X, click the Updater tab in the sidebar.
Click Select All above the app list.
Now, click Update.

4. macOS Catalina is running slow

Quite expectedly, some of the most reported issues on macOS Catalina are speed-related. Some background processes are hogging the CPU, most notably, the fileproviderd process. Thing is, macOS 10.15 Catalina heavily exchanges data with web-related processes, like cloud storages. There are countless rough edges to this process.

• Disable the fileproviderd process
  Go to Launchpad > Activity monitor

Here you’ll need to figure out what process is eating up the most resources. Watch out for the processes named mds and fileproviderd. If they take up 80-100% of CPU, try closing them using the [X] button above.

• Disable browser extensions

Browser extensions may be the culprit of many macOS Catalina issues. Leave the bare minimum of browser extensions and see how your Mac reacts.

5. Problem with Apple ID settings

This happens when Catalina is prompting you to update your Apple ID details. You’ve entered your password but the pop-up keeps coming back after some time.

• Solution: Enable Keychain in iCloud settings

Go to System Preferences > Internet Accounts > iCloud
Log in into your account and check the list of services that use iCloud.

Tick Keychain and enter your credentials.

6. Sidecar problems on macOS Catalina

Sidecar is a feature that doubles your workspace as you can use an iPad as a second monitor. The common issue here is inability to connect your iPad to the computer. First off, make sure you have iPadOS installed on your iPad. Then, find your Mac in the list of Sidecar-supported models:

• Late 2015 27″ iMac
• 2017 iMac Pro
• Mid 2016 MacBook Pro
• Late 2018 Mac mini
• Late 2018 MacBook Air
• Early 2016 MacBook
• 2019 Mac Pro

If your Mac is pre-2015, there’s still a workaround to enable Sidecar.

Open Terminal and paste in the following command:

defaults write com.apple.sidecar.display allowAllDevices -bool YES

Did it make the trick? Unfortunately, this combination is not guaranteed to work.

7. iCloud issues on macOS Catalina

Cannot download folders from iCloud

iCloud integration is one of those weak spots that produce tons of bugs. Fixes for such macOS Catalina problems are already on the way.

• Download each file individually

If you cannot download folders from iCloud, download each file individually. Unfortunately, this is the only available workaround at this point.

Did you know: Some part of your iCloud data is stored on both Google and Amazon data centers.

Cannot accept iCloud terms and conditions on Catalina

As of October 2019, this problem has too been widely reported. No matter how many times you’ve accepted the conditions, the legal disclaimer keeps coming up. It appears, that the problem occurs because you have more than just one device connected to iCloud.

• Go to System Preferences > Internet Accounts.
• Now, click the iCloud icon
  

You should see the Terms & Conditions pop-ups that is now in a pending state. Press Accept.

Repeat the procedure for all iCloud accounts and your devices you’ll see in the list.

8. Music Library freezing

The iTunes had been the centerpiece of music on macOS. With its removal things quickly went sideways. Since the arrival of the iTunes successor, Music app, many folks noticed their album artworks missing, Music Library freezing etc.
The typical case is your Mac says its “updating the Music Library”, spinning endlessly, without any progress. The issue is likely caused by obsolete Mojave caches and the remains your previous iTunes ecosystem.

• Empty your Music folder

And all music-related Library caches.

1. Back up your music and move it out of Music folder
2. Open ~/Library and delete any items titled “Music” or “iTunes”
3. Repeat for ~/Library/Caches
4. Restart your Mac and see if it worked

Don’t forget to put your music albums back where they had been before.

9. Wi-Fi issues on macOS Catalina

Wi-Fi not working after macOS Catalina update is pretty common. While your macOS is brand new, your Wi-Fi is still relying on some old protocols.

First, try to turn the Wi-Fi off and on again. If that doesn’t help you go to System Preferences > Network

Click on the dropdown menu that shows your Network.
Now, try choosing a different network — just to reset and shaken up the old settings

1. Connect to your default network
2. Check to “Automatically join this network”

Alternative fix with CleanMyMac X

To fix Wi-Fi problems on Catalina, we’ll use some of the tools from the free version of CleanMyMac X.

1. Download the app and open the Privacy tab
2. Find the Wi-Fi Networks option

Check all the networks in the list and click Remove.

This will make your Mac forget your old Wi-Fi stations and you’ll be able to reconnect again.

10. Bluetooth not available on macOS Catalina

If your Bluetooth is not working on macOS Catalina, there’s one easy trick you can do. You should try deleting your Bluetooth.plist files. Don’t worry, it will auto-create a new copy of itself.

1. Click Finder > Go > Go to Folder…
2. Type in: Library/Preferences

Now, look for a file com.apple.Bluetooth.plist

3. Delete it and restart your Mac.

11. Safari Extensions stopped working

There is a certain kind of Safari extensions, namely, .safariextz files that have been excluded from support in macOS Catalina. They no longer can be installed on Extensions page and are now considered “Legacy.”
RES, Ublock, and Bitwarden are some of the notable extensions that Safari users will miss on Catalina. What’s happening is Apple gradually moving away from the accepted web extensions format (WebExtensions) to the iOS-compatible extensions.

• Accept this fact (or wait patiently)

If you are missing your favorite ad blockers or other extensions, the easiest is to switch to a different browser. There is also a possibility that the developers will overhaul their extensions to support Safari 13 but we all will have to wait until that happens.

12. Storage filling up for no reason

So you’ve upgraded to macOS Catalina only to discover that a big chunk of free space is missing. Some identified folder is eating up your storage but how can you find it? The issue could be related to Time Machine backups and clones of APFS snapshots stored in different locations.

• Slim down your Time Machine snapshots

Unable To Download Macos Catalina

You can perform this operation safely in CleanMyMac X.
Download the app (a link to free edition) and launch it.
In CleanMyMac X:
Click the Maintenance tab
Choose “Time Machine snapshots thinning

As a manual solution, paste in the following commands in Terminal:

tmutil listlocalsnapshots / tmutil listlocalsnapshots /System/Volumes/Data

This lists the local snapshots created by your Time Machine. If you’re ready to delete those, type in this:

deletelocalsnapshots <snapshot_date> </snapshot_date>

Experience your favorite iPad apps now on your Mac. With Mac Catalyst, developers can easily create Mac apps from the iPad apps you already know and love.

• Developer support: Developers don’t need to do anything for Sidecar support — it just works. Apps with advanced stylus support can use Tablet Events in AppKit to enable pressure and tilt for Apple Pencil. Additionally, developers can specify custom behavior for double-tap on the side of Apple Pencil through a changeMode event.

Continuity Markup and Sketch

• Continuity Markup: Write and sketch on PDFs or mark up your documents with Apple Pencil. See the updates live on your Mac as you mark them up on your iPad.
• Continuity Sketch: Create a sketch on your iPad using Apple Pencil and easily insert it into any document on your Mac.

Screen Time

• Usage reports: Screen Time creates usage reports that show you how much time is being spent on your Mac, which apps are used most, and how many notifications are received. With iCloud, Screen Time combines all your usage information and syncs Downtime settings and App Limits across iPhone, iPad, and Mac.
• Downtime: With Screen Time, you can schedule downtime so you (or your child) can only use specific apps you’ve approved.
• App Limits: With App Limits, you can set the amount of time you want to use your apps and websites. Set App Limits for total time, categories, or specific apps.
• Combined Limits: Create combined limits with a combination of app categories, specific apps, or websites.
• One More Minute: When a limit is met, you can tap “One more minute” to give you time to quickly save your work or wrap up a conversation.
• Communication Limits: Communication Limits let you control who your children can communicate with and who can communicate with them throughout the day and during downtime.
• Managed contact list for children: Parents can use Screen Time to manage the contacts that appear on their children’s devices.
• Family Sharing: Parents can configure Screen Time from any device — iPhone, iPad, or Mac — and have everything set up for their kids on all their devices.

Security

Unable To Download Macos Catalina From App Store

• Enhanced Gatekeeper: Gatekeeper will ensure that all new apps you install — from the App Store or the internet — have been checked for known security issues by Apple before you run them the first time and periodically thereafter. This extends the protection from the app’s source to include automated checks for what’s in the app.
• Data protections: macOS Catalina checks with you before allowing an app to access your data in your Documents, Desktop, and Downloads folders; iCloud Drive; the folders of third-party cloud storage providers; removable media; and external volumes. In addition, you’re asked before an app can perform key logging or capture a still or video recording of your screen.
• Activation Lock: All Mac models with the Apple T2 Security Chip now support Activation Lock — just like your iPhone or iPad. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you.
• Dedicated system volume: macOS Catalina runs in a dedicated, read-only system volume — which means it is completely separate from all other data and helps improve the reliability of macOS.
• DriverKit and user space system extensions: Previously many hardware peripherals and sophisticated features needed to run their code directly within macOS using kernel extensions, or kexts. Now these programs run separately from the operating system, just like any other app, so they can’t affect macOS if something goes wrong.

Find My

• Two great apps in one: Find My iPhone and Find My Friends are now combined in a single, easy-to-use app to help you locate the people and devices that are important to you.
• Find offline devices: Locate a missing device even if it’s not connected to Wi-Fi using crowd-sourced location. When you mark your device as missing and another Apple user’s device is nearby, it can detect your device’s Bluetooth signal and report its location to you. It’s completely anonymous and encrypted end-to-end, so everyone’s privacy is protected.
• Enhanced location notifications: Location notifications include the ability to schedule notifications for different days of the week, more useful place names, and enhanced privacy controls.

Approve with Apple Watch

• View passwords: Anywhere you need to type your Mac password, such as viewing passwords in Safari preferences, you can now double-click the side button on your Apple Watch to authenticate on your Mac.
• Approving app installations: Unlock a locked note, approve app installations, unlock settings in System Preferences, and modify root files, all with your Apple Watch.

Accessibility

• Voice Control: Voice Control is a new way to fully control your Mac, iOS, and iPadOS devices entirely with your voice.
• Accurate dictation: Voice Control improves on the existing Enhanced Dictation feature using the Siri speech recognition engine, so you get the latest advances in machine learning for audio-to-text transcription.
• Add custom words: Whether you’re writing a biology report, filling out a legal document, or emailing about a favorite topic, you can add custom words to ensure that Voice Control recognizes the words you commonly use.
• On-device processing: All audio processing for Voice Control happens on your device, ensuring that your personal data is kept private.
• Rich text editing: Thanks to rich text editing commands, you don’t have to rehearse before you speak. Making corrections is quick and easy. You can replace phrases by name. Try saying “Replace I’m almost there with I just arrived.” Fine-grained selection also makes it simple to select text. Try saying “Move up two lines. Select previous word. Capitalize that.”
• Word and emoji suggestions: If you need to correct a word, there’s a new interface just for that. Simply ask to correct a word, and you’ll be presented with a list of suggested replacements.
• Seamless transitions from dictation to commands: Voice Control understands contextual cues, so you can seamlessly transition between text dictation and commands. For example, say “Happy Birthday. Tap send.” in Messages, and Voice Control sends “Happy Birthday” — just as you intended. You can also say “delete that”, and Voice Control knows to delete what you just typed.
• Comprehensive app navigation: You can rely entirely on your voice to navigate an app. Comprehensive navigation is provided by navigation commands, names of accessibility labels, numbers, and grids.
• Navigation commands: Navigation commands give you quick ways to interact with macOS and apps. You can open apps, search the web, open Spotlight, and more.
• Names: You can easily navigate by telling Voice Control to select the name of an accessibility label for buttons, links, and more.
• Numbers: Say “show numbers” to see numbers appear next to all clickable items onscreen. Use this to quickly navigate complex or unfamiliar apps. Numbers automatically appear in menus and whenever you need to disambiguate between items with the same name. Just say a number to click it.
• Grids: If you ever need to touch a part of the screen that doesn’t have a control, use Grid overlays. Saying “show grid” superimposes a grid on your screen and allows you to precisely do things, like select, zoom, drag, and more.
• Hover Text: Hover Text displays high-resolution zoom of text, text fields, menu items, buttons, and more in a dedicated window. Just press the Control key when hovering over text with your cursor, and a window with zoomed text appears alongside the standard interface — helping you stay contextually aware. Text is crisply displayed in a font and color of your choice. And you can interact with buttons and type right in the zoomed window.
• Zoom Display: While using a second display, you can see the same screen up close and at a distance simultaneously. You can keep one monitor zoomed in and another at a standard resolution. Or keep a personal Mac zoomed in while giving a presentation.
• Simplified tab navigation: VoiceOver users will enjoy simplified keyboard navigation that requires less drilling into unique focus groups. The Tab key more simply advances through selection of elements — such as window stoplights, toolbar buttons, and scroll bars.
• Punctuation in iCloud: VoiceOver users often customize the way punctuation marks are spoken. These customizations are now stored in iCloud, giving you a consistent experience across macOS, iOS, and iPadOS.
• Additional international braille tables: macOS Catalina adds more international braille tables and lets you quickly switch between them.
• Improved VoiceOver support in Xcode: VoiceOver now reads aloud warnings, line numbers, and breakpoints in the Xcode text editor.
• Display color filters: Users with color vision deficiencies can adjust display colors using new color filter options. Your Mac shifts the colors onscreen, helping you easily differentiate areas of confusion. And you can turn this preference on and off through the Accessibility Options pane using Command-Option-F5.
• Tint your entire display: A new display option lets you tint your entire screen using a color of your choice. Some users may find that certain color tints help make text easier to read.

QuickTime Player

• Picture in Picture (PiP): With a single click in the navigation controller, you can play video in a resizable window that isn’t blocked by other windows, allowing you to watch while working on other things.
• Enhanced Movie Inspector: The Movie Inspector pane shows you even more in-depth technical information about the currently open media file. See key details such as video color space, HDR format, bit depth, scale, and aspect ratio.
• Open Image Sequence: Create an H.264, HEVC, or ProRes-encoded movie file by navigating to a folder of sequentially numbered images, then choosing your desired resolution, frame rate, and encoding quality.

• Transparent video support: Transparency in ProRes 4444 files can optionally be preserved when exporting to the HEVC format.

Home

• HomeKit Secure Video: With a home hub such as an Apple TV or HomePod, securely record video to iCloud when activity by a person, animal, or vehicle is detected by your HomeKit-enabled cameras. Choose to receive notifications when clips are recorded and view them in the Home app on your Mac. In the Home app, a timeline of recordings is available to play from iCloud. You can also share a recording, delete it, or save it to your Photos library.
• Audio in scenes and automations: HomePod and AirPlay 2–enabled speakers can now play songs, playlists, and radio stations from Apple Music in scenes and automations with your other HomeKit accessories.

International Features

• New multilingual setup for macOS: Choose your languages, including those for keyboard and dictation, in Setup Assistant, and customize your language preferences from the start.

• Cantonese keyboard predictions: The new Cantonese predictions for Traditional Chinese Cangjie, Sucheng, Stroke, and Handwriting keyboards bring more relevant character and emoji predictions to Cantonese users.
• Improved Japanese predictions: A new neural language model takes words typed earlier in the sentence into account, so predictions are more grammatically consistent and relevant to the subject matter.
• New fonts for Indian languages: Get 34 new fonts, including four system fonts and 30 document fonts, for languages like Gujarati, Hindi, Kannada, Odia, Punjabi, and many more.
• New Indian English Siri voices: All-new Indian English male and female Siri voices allow Siri to be more natural and expressive.
• New dictionaries: New dictionaries include Thai-English and Vietnamese-English.

Other Features

• iCloud Drive folder sharing:You can now share folders with a private link. Anyone who has access can see the folder in iCloud Drive, add new files, and get the latest versions of files.
• Restore from snapshot: If your third-party software is incompatible with an update you just installed, use macOS Recovery to restore from a snapshot of your computer taken right before the installation. macOS and all your apps will work just as they did before you installed the update.
