Big Sur Changes Time Machine External Hard Drive to APFS and Read Only
Can't find info on this anywhere, wondering what I could be doing wrong.
I have two external hard drives (one brand new) that I use for redundant back-ups via Time Machine, and also to store other files. Both Seagate 10TB drives.
With the upgrade to Big Sur, the older external drive formatted for Mac OS Extended (Journaled) is a-ok, and I can manually drop other files there.
I formatted the new drive to be the same, dropped files in, no problem.
BUT, when I set it as a backup for Time Machine, it changes it to APFS, and then after the back-up, becomes "read only" and I can't drop files in.
