Change file sharing permissions on MAC HD using OS Ventura
I can't copy (write) any files from my desktop to my seagate external hard drives that are Mac OS Extended (Journaled).
I've reformatted both drives, but no luck. I was able to copy folders to the drives until I upgraded to Ventura, I think. The drives work on a separate computer, so it's not the drive or cable or a power issue.
I tried changing the permissions in my MAC HD. After Command I on the HD, I unlock the permissions. When I click on +/- icon under sharing and permissions to change the name or the permission, I get this message The operation can’t be completed because you don’t have the necessary permission.
The name is "system" in the sharing & permissions section. It should be something else, but when I click on the + icon to change the name, I get the same message in bold above. How do I change permissions? Anf if I do change permissions, will I be able to copy(write) folders ro my external hard drives?
