Not able to update any app on my late 2018 Mac Mini
On my late 2018 Mac Mini I have a problem that will not allow me to update or upgrade any apps. Error message “ Installation cannot proceed because installer is damaged” Redownload the installer and try again. I downloaded several times and the same error. I shutdown and powered up in Safe Mode but the same error when I tried to install upgrade. I used Disk Utility and ran first aid on MacIntosh HD and it did not find anything and said that it was “ successful. Shutdown again and each time used each of the 3 Recovery Utility versions with no solution. I was able to restore from Time Machine backup and was able to login but when I tried to install is or apps the same problem exists.
