Apple login issue with Monterey
A bizarre login issue has come up. I assume it is related to my recent OS update to Monterey. When I go to an Apple site to log in, such as this community forum just now, I am given a small login window with an icon of a lock at the top. My user name is already filled in, but it is the user name for this computer, not my Apple user name, which is my email address. My Apple password does not work. Instead, my computer login password works. Thatʻs right. Somehow, Apple has confused my Mac and my apple.com user names and redefined my Mac system login as my Apple login. If I select the option "login under a different user name," I then get a different login window that allows me to enter my Apple user name and accepts my usual Apple password. I called Apple support yesterday on this issue on on one other issue and the person had no clue what was going on. Not helpful at all. No suggestions, no fixes. What gives?
