I decided to just revert back to Mojave, months of updates hasn’t really convinced me Catalina is a good release. But my biggest gripe is how clearly Apple pulled a Vista sort of issue with me in terms of their lockdown security of Catalina. Its like Vista User Account Control system only worse. Trying to install anything that needs core OS access involves multiple approvals with permissions. Can we just get an off switch for some of this nanny stuff? It just keeps getting worse on Mac OS.
Getting as bad as Windows with all the updates. My Mac Mini took like 10 minutes to install this update. Not sure I believe it was just security updates?
Seems like my MacBook Air 2020 froze at the update.
