Unable to update apps on app store
I was using different Apple ID in the beginning.
That was live.com
I decided to use iCloud mail address as my Apple ID
Whenever I try to update anything from my MacBook Air, only the old id is auto filled.
I remove that every time and type the new Apple ID
But after entering the password of new Apple ID, the app is not installed and again login is asked with old id auto filled.
Now I just went to recovery and reinstalled Catalina.
Nothing changed.
I want to install fresh copy of Mac by deleting everything
Is that possible?
Or can we fix it without deleting the Mac itself?
I want to update Xcode. But it is not happening
MacBook Air 13″, macOS 10.15
