Since it is still in its early stages, there have been many macOS Catalina issues. This is not surprising, as the newly released operating system always does. However, this does not mean that we should ignore them and hope that Apple will release updates as soon as possible, rather than later.
From installation issues to hardware and software that aren’t working, we’ve provided a series of fixes to solve many of the macOS 10.15 Catalina issues that people encounter.
But what if I have a problem with macOS Catalina that we don’t cover? In this case, please pay attention to and post details to us, we will try our best to find a solution. Also, if macOS is not already installed, be sure to visit our How to download and install the macOS Catalina guide to get new software on your Mac or MacBook.
How to fix macOS Catalina download problems
A common macOS Catalina problem that people encounter is that macOS 10.15 cannot be downloaded. Some users see an error message stating “MacOS Catalina failed to download”.
On the other hand, others saw a “network connection lost” error message when trying to download macOS Catalina.
In addition, some people received the error message: “Cannot continue to install macOS. The installation needs to download important content. The content is currently not available for download. Try again later.”
There are several reasons why you may be experiencing this issue. Probably because many people are trying to download macOS Catalina at the same time. If you think this is the case, try again later during off-peak hours to see if the download works. You can also check the real-time status of the Apple Server to make sure everything is working.
Another reason may be that there is not enough space on your computer at all. Typically, if there is not enough free storage on your Mac, the macOS download will fail.
To determine what you want to do, open the Apple menu and click About This Mac. Select “Storage” and check to make sure there is enough space on the hard drive. You need at least 15GB of free space. If the battery is low, open the Apple menu, click About This Mac, and go to Storage > Manage and free up some disk space there.
Switching from a Wi-Fi connection to an Ethernet cable may also be worthwhile to ensure that your Internet connection is as reliable as possible.
If you still can’t download macOS Catalina, try to find some downloaded macOS 10.15 files and files named “Install macOS 10.15” on your hard drive. Remove them, then restart your Mac and try downloading macOS Catalina again.
Also, if that doesn’t work, try opening the App Store and clicking “View My Account” to see if there is anything in the “Unfinished Downloads” section. You may be able to restart the download from there.
Finally, try to log out of the store to see if you want to restart the download.
How to fix “gateway timed out” error when downloading macOS Catalina
In addition, many people complain that the download stops at 511.5MB when downloading and installing macOS Catalina, and the system throws a “gateway timeout” or “gateway error” error.
If you encounter this issue, try to start your Mac in Safe mode (hold Shift while booting, then try to download and install macOS Catalina).
How to fix macOS Catalina install problems
If your macOS Catalina problem is in installing the operating system, first make sure you check out our how to download and install macOS Catalina guide, which will take you through the steps you need to take to safely install the new operating system.
First of all, you’ll want to make sure you have a Mac that can run macOS Catalina. The following Macs are compatible:
- 12-inch MacBook (2015 and later)
- MacBook Air (2012 and later)
- MacBook Pro (2012 and later)
- Mac mini (2012 and later)
- iMac (2012 and later)
- iMac Pro (2017)
- Mac Pro (2013 and later)
When you have a compatible Mac and the macOS Catalina download completes, but there’s no prompt for the installation to continue, then search in your Mac’s application folder for a file called ‘Install macOS 10.15’. Double-clicking the file should begin installation.
If you encounter the macOS Catalina problem where the installation fails due to low disk space, simply restart your Mac and press Control + R while it’s booting to enter the Recovery mode. Select ‘Disk boot’ to boot normally, then remove unnecessary files to make space.
macOS Catalina is stuck on ‘Setting Up Your Mac’
We’ve had readers contact us saying that after installing macOS Catalina, their Macs show the ‘Setting Up Your Mac’ message, but nothing else happens.
If this is the case, you’ll need to force a reboot of your Mac or MacBook. Don’t worry, the ‘Setting Up Your Mac’ message means the update is finished, so you won’t lose any data or damage anything by restarting your Mac.
To do so, press and hold down the power button for a few seconds until the Mac or MacBook turns off. Wait a few more seconds, then turn it back on. Your Mac or MacBook should now boot into macOS Catalina successfully.
If you’re struggling to free up disk space, look out for hidden Time Machine files that may be taking up large amounts of space.
Once you have freed up enough space, retry the installation.
If macOS Catalina encounters a problem at the end of installation, and then shows an error message, restart your Mac and press Command + Option + R on your keyboard while the Mac boots to start up the recovery system over the Internet. You can also try Shift + Option + Command + R.
If your Mac continues to fail to boot, follow Apple’s instructions on creating an external Mac startup disk.
It may be worth restarting your Mac in Safe Mode, then trying to install macOS 10.15 Catalina from there to fix the problem.
How to fix macOS Catalina login problems
If you’re having trouble logging into your Mac or MacBook after installing macOS Catalina, or you’re stuck in a loop where you log in, then get logged out again, the following steps might help.
First, restart your Mac and hold down the Command + S keys on your keyboard as it boots up.
This will boot you into a command prompt. Now, enter in the following:
/sbin/mount -uw /
Press Enter on your keyboard. Then enter in the following:
This removes a file, which makes it appear like you’re starting Catalina up for the first time. Don’t worry, nothing important is getting deleted. Press Enter, then restart your Mac.
You will then be asked to create a new admin user account.
How to fix macOS Catalina email problems
Some readers have got in contact to let us know that they are experiencing problems with the Mail app in macOS Catalina. If you use Mail to read and send emails, and it’s not working correctly after installing macOS Catalina, read on to find out how you can fix the most common issues.
If Mail keeps crashing while you use it, open up Finder and then click on ‘Go’ from the top menu and select ‘Go to Folder’.
Next, type in:
~/Library/Containers/com.apple.mail/Data/Library/Saved Application State/
Scroll down and find ‘com.apple.mail.savedState’ and then move it to Trash.
Next, go back to the ‘Go to Folder’ window and type in:
Find com.apple.mail and com.apple.MailServiceAgent and move them, either to Trash or somewhere temporary (like your desktop).
Then, go to:
Find Envelope Index, Envelope Index-shm and Envelope Index-wal to Trash. Empty Trash, then restart your Mac and see if that works.
macOS Catalina breaks search in Mail – here’s how to fix it
There are reports that the search function no longer works in the Mail app after installing macOS Catalina.
The first thing to try, if you encounter this problem, is first close Mail completely. Then hold Shift and click on the Mail icon to open it in Safe Mode. Then, close Mail again, then hold Shift and open Mail again.
Finally, close Mail yet again, then reboot your Mac. Open Mail normally, and search should work again.
If that doesn’t work, and you’re using a Gmail account, that could be the issue.
Go to System Preferences > Internet Accounts and turn off Gmail. Reboot the Mac and load up Mail to see if search works.
If it does, you can then go back to System Preferences and add your Gmail account again.
Is macOS Catalina running slowly? Here’s how to fix it
Once macOS Catalina is installed on your Mac or MacBook, you may notice that your device is running slower than before.
If macOS Catalina also showed a notification that said “Optimizing Your Mac: Performance and battery life may be affected until completed,” then this is normal, as macOS Catalina is doing things behind the scenes which can initially impact performance.
After a day or so, your Mac should be running just as well (if not better) as before. If you don’t see an improvement by then, try restarting your Mac or MacBook.
Another thing to check is to make sure that all of your apps and software are updated to the latest version. If any of them have issues with Catalina, that could be slowing down your machine.
You can also open up the Apple menu and select ‘System Preferences’. From the window that appears, click ‘Users & Groups’. Select ‘Login Items’ and then select the apps you want to stop opening at startup and click the small minus sign below the list.
It’s also worth making sure all of your apps are updated. Check the App Store for any available updates, or the app’s website.
You can also try restarting your Mac to see if that helps. If it doesn’t, force-quit any apps that appear to be taking up a lot of RAM. You can identify these by using Activity Monitor (in /Applications/Utilities) to establish what apps and processes are using up the most CPU or RAM. Its CPU tab lists active processes, with a real-time view of what’s going on.
To force-quit an item, click it in the Activity Monitor list, click the X at the left of the toolbar, then confirm you want to force-quit.
Also delete the cache. Open the Finder window, select ‘Go’ from the top menu and select ‘Go to Folder’.
In the text box that appears, type /Library/Caches.
Remove the data from inside every folder. Now repeat the process with /Library/Caches (without the symbol). Running the Repair Disk tool from within Disk Utility may also help, and for more solutions check out our How to speed up your Mac guide.
How to fix macOS Catalina battery issues
As with the performance issues above, you may find that at first your MacBook’s battery life is a lot shorter. Again, this is probably because macOS Catalina is doing some background work to set itself up – and after a few hours or a day, things should have settled down and your battery life should be back to normal.
If it isn’t then make sure all your apps are updated. You can also click the battery icon on the top menu bar, which will show you what apps and processes are taking up a lot of your battery life. Close those and see if the battery improves.
If it does, then make sure the apps in question have been updated, and check any of their settings to see why they would be taking up so much battery life in macOS Catalina.

How to fix macOS Catalina mouse problemsIf you’ve installed macOS Catalina and found your mouse no longer works, open up the ~/Library/Preferences/ directory in finder and select and delete the following files:
You may need to restart your Mac to get the mouse working.
How to fix macOS Catalina MacBook keyboard problems
Here’s an odd one. Some people have been complaining that after updating to macOS Catalina, the keyboards of their MacBooks no longer work.
Luckily, there’s quite an easy fix. Restart the MacBook, and once macOS Catalina has loaded, close the lid of the MacBook for a few seconds. Then, open it back up, and the keyboard should begin working again.
Hopefully Apple releases a fix for this bug soon – but at least it’s relatively easy to get around for now.
How to fix macOS Catalina Bluetooth issues
To fix issues with Bluetooth devices not working in macOS Catalina try opening up Finder and then click on ‘Go’ in the top menu, then ‘Go to Folder…’. Type in ‘/Library/Preferences’.
From there, you should see a file called ‘com.apple.Bluetooth.plist ‘. Select and delete the file (or move it to another folder for safe keeping), then restart your Mac and try connecting your Bluetooth device again.
How to fix macOS Catalina boot problems
If you’ve installed macOS Catalina, but your Mac won’t start, then restart your Mac and hold down Command, Option, P and R, which will reset the NVRAM (non-volatile RAM).
Hold the keys down until the computer restarts and you hear the startup chime for the second time. Release the keys after you hear the second startup chime. The PRAM will be reset as well.
While in Safe Mode, run Disk Utility to see if that will fix any macOS Catalina boot problems.
For other ways to fix a Mac that won’t start, check out our guides how to Use OS X boot options to troubleshoot your Mac and how to fix a Mac that won’t start.
How to fix macOS Catalina Finder problems
Some people have found that Finder has been crashing or becoming unresponsive after updating to macOS Catalina.
If you have encountered this problem, open up Terminal and enter the following command:
Press Enter. You will see a highlighted in Finder. Select the file, then delete it. Next, restart the Mac.
Apps won’t work in macOS Catalina
One of the most controversial changes included with macOS Catalina is the fact that it no longer supports 32-bit apps. This means any apps that don’t have a 64-bit version will no longer work.
Apps that will be killed off in macOS Catalina include Transmist 4.1.7, 1Password 2.12.2, iStats Menu 2.9 and QuickBooks 2015. You can view the full list of the apps at The Tape Drive.
While most apps will hopefully have 64-bit updates, there will be many that don’t, which is bad news if you rely on them and upgrade to macOS Catalina.
If you’re concerned that an app you rely on will no longer work in macOS Catalina, you should check to see if you have any 32-bit apps on your system.
To do this, click on the Apple icon at the top of your screen, then select ‘About This Mac’. Click ‘System Report’ and then go to the ‘Software’ section.
Click ‘Applications’ and you’ll see a list of apps. There will be a column called ’64-bit (Intel)’. If an app has ‘No’ in that column, then it means it won’t be supported in macOS Catalina.
You can check the list on The Tape Drive as well to see if your apps are listed there.
If you do have any 32-bit apps installed, you’ll need to check to see if there is a 64-bit version (if the app has a website, it should say whether one is available).
If not, you’ll need to find an alternative app that performs the same function but is 64-bit. Our guide to the best Mac apps will help you.
How to fix macOS Catalina Sidecar problems
Sidecar is one of the best macOS Catalina features, allowing you to use a compatible iPad as a second screen.
However, if you’re having issues getting Sidecar to work in macOS Catalina, there are a few things to check.
To use Sidecar, you need one of the following iPad models:
- iPad 6
- iPad 7
- iPad mini 5
- iPad Air 3
- Any iPad Pro
The iPad needs to have the new iPadOS software installed as well.
You also need to make sure you have a compatible Mac:
- iMac 27-inch (Late 2015 or newer)
- MacBook Pro (2016 or newer)
- Mac mini (2018)
- Mac Pro (2019)
- MacBook Air (2018)
- MacBook (Early 2016 or newer)
If you don’t own one of the above, all is not lost. Reddit user u/dotmax has discovered that you can use Sidebar on older Macs by running a Terminal command – but we wouldn’t recommend it, as the results aren’t great.
Make sure you check out our how to use Sidecar in macOS Catalina guide for an in-depth look at this excellent feature.
How to fix macOS Catalina Wi-Fi problems
If you’re having issues with connecting to the internet, either via Wi-Fi or an Ethernet (wired) connection after installing macOS Catalina, then try starting your Mac in Safe Mode and see if you can connect.
If you can, it means that there’s an issue with an app or extension that you have installed. Make sure you have updated your drivers and apps, and keep an eye out for an Apple update in the future. /Source : techradar
