Apple Releases macOS 15.3.1 with security fixes

Word of warning:
The 18.3.1 update worked fine on my Wife’s 14+
But on my relatively new 15 it corrupted the logging for shared calendar and contacts.
Was stuck in an endless verification loop:
Adding password, which failed, then it asks for it again. Yes I put in correct password!!
Went to Verizon who instantly said it’s an Apple problem-go to them!
Of course there is no Apple Store for over a 100 miles away.
Went to GEEK Squad at Best Buy, and explained itt acted up during update.
Fine fellow realized login was corrupted for shared calendar and contacts (linked with wife’s iPhone).
Strange: Email. The same email address was fine, but same email for calendar & contacts was corrupted.

He blasted the login, then re-entered it… Verification loop then went away, but then he re-linked the calendar & contacts to wife’s iPhone. Worked!!!
I grabbed for my wallet: He brushed me away! “No Charge!”
Yes I have his business card!

sounds like a nightmare !

Nice of him to help you, especially for no charge.
