Hi, I have tried 3 times and I get the same error message on running the software update install.
It downloads the 8.09 GB install files and then just states (null) and asks to upgrade now. Which when clicked, starts the process again.
Any ideas?
MacBook Pro with Touch Bar
I have the same problem and already tried both things; starting the Macbook in safe mode and creating another user account. None of them worked.
Hi, many thanks for your comments. For an unKnown reason, after a 3rd attempt at installing it, it worked. There is no reason as to why, but it took about 40min to download and then, about an hour to install. at which point it restarted and displayed the Catalina welcome page. Sadly I can't be of much more help on the issue.
elixirEU,
Thanks for getting back to us and for providing us an update. Glad to hear you were able to install macOS Catalina. Have a wonderful rest of your day.
Kind regards.
Hi elixirEU,
Welcome to Apple Support Communities. I understand you're unable to update to macOS Catalina as you continue to see "Upgrade Now." I'll be happy to help and point you in the right direction.
If you haven't tried yet, I recommend to start up your Mac in safe mode. You can review the benefits and details of how to start up your Mac in safe mode through this helpful article: Use safe mode to isolate issues with your Mac Once that's done, you can then restart your Mac normally and attempt the update for macOS Catalina. In addition, please be sure you have enough available storage space for the update. Here's how: How to free up storage space on your Mac
For any reason you continue to experience the same behavior, I suggest creating another user account on your Mac and attempt to update the software. If needed, here's how to create a user account on your Mac: How to test an issue in another user account on your Mac
Cheers!
