"Sign into the iTunes Store" failure
So I have a problem logging into the app store.
When I go to update apps, I get a "Sign into the iTunes Store" pop up that is already populated with an old Apple ID used on this Mac.
After I enter my own and type the password, it stutters for a minute as if the updates will begin, but then I get another pop up.
Hitting download brings it right back up, which happens 4 or 5 times before it stops and brings me right back to square 1.
My connection is strong, clock is correct, airdrop works fine with my phone which is on the same AppleID, iMessage doesn't work either. There's a mixup somewhere with my Apple ID but i can't figure out what it is.
Thanks in advance for any help.
