Mail does not open due to permissions issue. Also apps in store will not download unknown error.
I received a popup when saying not authorization exists for this action when trying to modify passwords in keychain. I followed a forum that suggested I change admin to read and write and click apply to enclosed items. After this was done my keychain login disappeared and i had to follow a different forum to recover it. Now I am getting a Firefox is open only one copy at a time can be open error and mail prompt that says mail can't be opened because you don't have the necessary permissions. Also, I cannot download in App store it gives me we cannot complete your purchase unknown error for everything in store.
