Months ago, I created a disk image on a large external drive to house my Time Machine backups.
Yesterday…something went sideways with the permissions of my entire installation.
Included in this permissionpocalypse, is somehow my Time Machine dmg.
I am, now, unable to backup to Time Machine because the disk image is considered read only by 'system' and Finder informs me that I do not have permission to change the permissions of the image.
When I attempt to Verify the image in DiskUtility, I am told that: 'The image does not have a checksum so cannot be verified.'
So…before I investigate ways to super user sidestep my lack of permission to change TM dmg permissions, I figure I should probably know what those desired permissions are supposed to be.
EDIT: I'm using Mojave 10.14.6 (18G2022)
