How do I delete someone else's ID account in my App's on my Mac?
I was looking for a cursor locator, so a friend of mine sent me a link to buy PinPoint via my App's store, but when I clicked on his link, it wanted the password to his email address. Whatever I tried, I couldn't get rid of it. So I purchased PinPoint on my second computer, but my main computer (Mac Pro), there's a PinPoint update, so when I click on Update, it wants my friends password.
How do I get rid of his email address and see mine? I logged out and back into my account, but that didn't help.
Any suggestions?
Thanks!
