How do I get rid of pop ups: iCloud, Facetime and others
I've been setting up my three Late 2013 iMacs with Mojave and Catalina. Almost every time I boot into one of these machines, Apple starts annoying me with various message about iCloud, Facetime, etc. I enter my password, add the code they send me, do various things asked of me, and then next time I boot up (on any or all of the machines), similar messages appear.
I don't use iCloud, Facetime or anything like that. So it's rather annoying that during setup, I've had to enter these details 20 or 30 times.
Ques
How do I tell my three machines (and each has Mavericks, Mojave and Catalina installed) that I never ever want anything to do with iCloud and it's associates.
