On Mac OS 10.15–Go For Mac OS 11
I know a lot of you are on Mac OS 10.15. You have a “late model” Mac and you have held off on upgrading to Mac OS 11 pending my recommendation. I have had the chance to do some of these installations and while they can take SEVERAL HOURS if you are on an older version of the Mac OS — they are pretty painless if you are already on Mac OS 10.15.
If you have a backup of your Mac already, you can probably do the upgrade yourself by going to the Apple Menu, System Preferences, and Software Update. Depending on your internet connection the process will take 60 to 90 minutes.
You’ll want to have Mac OS 11 by September, in my opinion. During the fall, the next Mac OS will come out and I will have you wait a few months again before it is installed. New OS’es never have to be installed on day 1, but eventually you want them because they provide CRUCIAL security fixes.
