macOS Monterey external TimeMachine disk is read only.
macOS Monterey external TimeMachine disk is read only.
I have 5 TB external Seagate disk I want to use as a TimeMachine backup as well as secondary storage. Once the disks is setup as TimeMachine Disk, the disk is READ ONLY with no dropdown options to change the rights. The weird thing is IF I USE a backup drive from my OLD MacBook Pro, Time Machine on the new MacBook will use that drive as well as providing storage for iTunes, etc.
