All my previous OS updates have been smooth with no consequences with the exception of plug-ins. Thinking the new OS has been out long enough that all might be working. Do you have anything giving you problems at this time?
Just finish upgrading laptop and desktop to the new OS No mayor disasters. A couple of the programs are not working but I'm happy with the update. All PS plug ins are doing fine. Now I need to dig in and find out what is new !!!
all is fine on my end. Only issue I had was a few weeks ago during ilife update. it froze midway and would not boot. had to get apple support and so a safe boot; but the update eventually finished and no problems since.
