MacBook keeps requesting a sign in to my brother's Apple ID every time I log in
This issue has been happening for a while but I just keep ignoring it but it's driving me insane. Every time I restart or log in to my computer I get a pop-up that requests I sign in to my Apple ID/iCloud account, but the account's email that pops up is my brother's, not mine. My computer is set up with my Apple ID and works perfectly fine and when I click "cancel" on the pop-up it does go away (until I log in/restart again). When I try to see who is all logged in on my computer I am the only one that pops up. I have had my brother log out of his Apple ID on my computer in the past but that did not stop this issue. How do I stop this prompt for good?
MacBook Pro 13″, macOS 15.0
