Update to catalina

Hello Faisal1599,

Welcome to the Apple Support Communities. I understand you're unable to update because it shows the requested version is not available and will do what I can to help.

Here are some suggestions:

• Check the compatibility of your Mac and the other steps here: How to upgrade to macOS Catalina
• If possible, check the Mac App Store to see if you can update from there: Get macOS Catalina
• Restart your Mac from the Apple () menu then Restart. Check for the update again.
• Check the software update in safe mode: Use safe mode to isolate issues with your Mac

Enjoy your day.

Keep searching on here. I spent a long time on chat and did everything they said but nothing helped. I found a post earlier on here but don’t see it just now. But someone posted how to reset updates via terminal with one line of code. I did that and it was perfect.

Try this for MacOS 10.10 or later:

sudo softwareupdate --clear-catalog

This resets the Server back to Apple, the default.
