Everytime you open Logos, the "sign in" screen appears you are required to enter an email and password.
The Mac User Account does not have correct permissions on key configuration files.
- Quit Logos if it is already open.
- Open Finder to the Applications folder.
- Navigate to Utilities.
- Open Terminal.
- Enter the following commands, one at a time, exactly as they appear below:
chmod 755 ~/.config
chmod 755 ~/.config/.mono
chmod 700 ~/.config/.mono/keypairs
If they are entered correctly, they likely will not return any message or response. Open Logos and sign in. It shouldn't prompt you again next time.
