Time Machine backup not functioning properly.
Automatic time machine backups on 2015 MacBook Air (running Monterey 12.6.8) not functioning properly. They won't allow selection of the HD disk; only offer external hard drive or other Airport capsule backup. looked into updating to Ventura but that is not offered. Need to get it internally backed up before a Genius Bar appointment Saturday, August 26.2023.
