Re: I cannot login to App Storein response to tappingseekerSolved
I discovered a solution in one of Apple's support communities. Sadly I do not remember which one it was or who wrote it, as I serached so many hints. I hope he or she will excuse me.
Here is the solution for my problem:
Please note that it will delete your Apple ID account information for the current user and you will need to log in again.
- If the App Store is opened and stuck in the login process, force close it.
- Open the Terminal
- Issue the following commands:
sudo pkill -9 -f Account sudo rm $HOME/Library/Accounts/*
Open the App Store and log in
I hope, it will help others too! Good luck!
