XCode 11.1 install fail

XCode 11.0 update installed automatically under MacOS 10.14.6 and works fine. After MacOS 10.15 (Catalina), XCode 11.1 update repeatedly fails to install after downloading. Version 1.0 still works under MacOS 10.15 however. What am I doing wrong? Is it me or Apple? iMac (Retina 5K, 27-inch, Late 2014)

iMac Line (2012 and Later)

Hello JKenderdine,



Thanks for that info and for choosing the Apple Support Communities. If I understand correctly, you are unable to install and open Xcode on your iMac as expected. You can figure out if unexpected behavior is related to a user file or setting by trying to reproduce the issue from another user account. This process includes creating a new user account, logging in to it, and testing for the issue.



How to test an issue in another user account on your Mac



Next, use safe mode to start up your Mac as it does the following things:



  • Verifies your startup disk and attempts to repair directory issues, if needed
  • Loads only required kernel extensions
  • Prevents Startup Items and Login Items from opening automatically
  • Disables user-installed fonts
  • Deletes font caches, kernel cache, and other system cache files



Log in to your user account and test the issue while in safe mode and then restart normally and test the issue again.



Use safe mode to isolate issues with your Mac

Graphics performance limited in macOS Recovery, safe mode, or Guest User mode



Cheers!

Tried all of the above, with a couple stumbles. Everything check out oK, but update from 11.0 to 11.1 still failed. What finally worked was to first move Xcode app to separate safe drive (takes a long time), then download a fresh copy (now 11.1) from iCloud. That that worked (again long process). Install successful, runs fine. Deleted apparently corrupted 11.0 copy.


Thanks for your suggestions. I learned something even though ultimately it didn't work for me.
