As it is still in its early days, a number macOS Catalina problems and issues have arisen. This isn’t surprising, as this is always the case with newly-released operating systems. However, that doesn’t mean that we should just ignore them, and hope that Apple will release updates sooner rather than later.
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.
However, 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. And, if you haven't installed the macOS yet, 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.
Others, on the other hand, are seeing "The network connection was lost" error messages when they try to download macOS Catalina.
In addition, a few get 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 encounter this issue. It may be because a lot of people are trying to download macOS Catalina at the same time. If you think this is the case, try again later on a non-peak time to see if the download works then. You can also check the live status of the Apple Server to make sure everything is alright on Apple's end.
Another reason could be that you simply do not have enough space on your computer. Typically, a macOS download fails 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' 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.
And, 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 logging out of the Store to see if that restarts the download.
How to fix "gateway timed out" error when downloading macOS Catalina
In addition, there’s been a lot of complaints regarding the download stopping at around 511.5MB when downloading and installing macOS Catalina, and the system throwing up a "gateway timed out" or "bad gateway" error.
If you are having this issue, try starting your Mac in Safe Mode (hold down Shift on the keyboard while it boots), then try downloading and installing macOS Catalina again.
