Tried to log into macapp store today to purchase an app. States there was an unknown error and my password was wrong. Have not changed my password and use 1password. However typed it in manually - still no joy. Went through password change process with apple ID - which I could log in to! Changed password and then tried to re log in manually - no joy. Restarted mac, tried again, no joy. Anyone else having this issue, or had this issue and have a solution? I would like to give Apple some more of my money, but I am suspecting that they feel they have enough and hence don't want it anymore?
Thanks in advance.
Can you sign in to the itunes store? If so, sign in and check to make sure your credit card data is correct (including expiration date).
You could try deleting the app store plist from your user library and then restarting, though I don't know how much success will come from that: (Library/Cookies/com.apple.appstore.plist)
You could try creating a new user account in system preferences and attempting to sign in to the App store with your credentials while logged into the new account.
You could try signing in while in safe mode (restart the computer, hold SHIFT before the blue screen appears. Everything will be slow so don't worry about that).
The app store has been a mess in general for the last year so these are troubleshooting suggestions.
