Montery 12.4 issues on iMac?
I have a 2017 27-inch iMac running 12.3.1 Montery. I have the little red circle over my System Prefs icon on the dock with a '1' in it indicating their is a software update available for 12.4.
I was about to update it, but I typically check online first to see if there are issues with updates before doing them and with 12.4 there seems to be quite a lot, especially installation issues. But, these reports are a few months back and I wondered:
A. Is it now safe to do this update?
B. If it goes wrong can I go back to previous OS version without having to do clean install and mess about for a day re-installing software and codes etc?
C. Is there any way to get rid of the annoying red circle with a '1' in it on my System Prefs icon on the doc so I'm not constantly reminded of it in case I don't want to upgrade anytime soon?
Thanks.
