Welcome to our guide on how to fix macOS Catalina problems. From installation issues to hardware and software that doesn’t work as it should, we have a range of fixes that should address many of the macOS 10.15 Catalina problems people are encountering.
But what happens if you encounter a macOS Catalina problem that we haven’t covered? In that case, follow and tweet the details to us and we’ll do what we can to find a solution.
If you haven’t already, make sure you visit our how to download and install macOS Catalina guide for the step-by-step process of getting the new software on your Mac or MacBook.
Some users are also seeing “The network connection was lost” error messages when they try to download macOS Catalina.
Another common macOS Catalina download problem shows the error message: “Installation of macOS could not continue. Installation requires downloading important content. That content can’t be downloaded at this time. Try again later.”
There are a few reasons why you may get this problem. It may be because a lot of people are trying to download macOS Catalina at the same time. If this is the issue, try again later to see if the download now works. You can also check the live status of the Apple Server to make sure everything is alright on Apple’s end.
The macOS Catalina download may also fail if you do not have enough storage space available on your Mac. To make sure you do, open up the Apple menu and click on ‘About This Mac.’
Select ‘Storage’ and then check to make sure you have enough space on your hard drive. You need at least 15GB free. If you’re running low, open up the Apple menu, click ‘About this Mac’ then go to Storage > Manage and free up some disk space there.
It may also be worth switching from a Wi-Fi connection to an Ethernet cable, to ensure your internet connection is as reliable as possible.
If you’re still having problems downloading macOS Catalina, try to find the partially-downloaded macOS 10.15 files and a file named ‘Install macOS 10.15’ on your hard drive. Delete them, then reboot your Mac and try to download macOS Catalina again.
If you still have a problem downloading macOS Catalina, open up the App Store, click ‘View My Account’ and see if there is anything in the ‘Unfinished Downloads’ section. You may be able to restart the download from there.
Finally, try logging out of the Store to see if that restarts the download.
If you’re having problems installing macOS Catalina, 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)
If 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-click the file to begin installation.
If you encounter the macOS Catalina problem where the installation fails due to low disk space, restart your Mac and press Control + R while it’s booting to enter the Recovery mode. Select ‘Disk boot’ to boot normally, then remove any files you no longer need.
