Helpful article. It recommends getting rid of unused apps to make sure you have enough room to install. But there is nothing there that gives a clue on how much room is needed! Regarding making an archived backup: I’m too cheap to pay for iCloud storage so for at least a year now I’ve been making backup’s to my Mac. Certainly not as convenient but I’m not paying a monthly fee for the privilege. The article mentions “if you want to encrypt the backup” is bad advice. Only last month I learned to my astonishment that my unencrypted backup’s were not backing up keychain’s, pw file, and health data. The article should say “be sure to encrypt the backup” if you want these items backed up.
