macOS Big Sur - I have an external hard drive with Time Machine backups from my prior Mac. I am simply trying to copy a few files from my old Mac (located inside the backups.backupdb folder) to my current Mac. I have tried this by simple copy/paste via Finder from the external hard drive, as well as browsing the external hard drive from Time Machine on my current Mac, and doing a restore. In both cases, I get an error 36 in Finder - specifically "The Finder can’t complete the operation because some data in “file.mp3” can’t be read or written.."
So then, after some research, I was actually able to get the copy/paste function to work by using terminal and the
cp -R command. So now the needed files are on my current mac, but if I try and open any of them, I get an error message about the file not being compatible.
Now I'm attempting to see if this is a permissions issue. Whereas most files on my mac list me as Read/Write permissions in Get Info, these copied files do not. Here is what the Get Info Permissions looks like on these files:
If I try and add myself to the Permissions list via the plus button of this window, I get another error 36 - the operation can't be completed. How can I get myself on this permissions list? I have already tried First Aid in Disk Utility on the external drive, and while it said it ran successfully, it did not update the permissions.
UPDATE #1: I was able to add myself to the Permissions of the files on the external hard drive. The errors still persist, however.
