I have a MacBook Air M4 running Tahoe 26.7 but this also happens on 27.0. I try to backup my iPhone 17PM to the Mac via Apple Original cables (tried 3 of them) but each and every attempt failed with a disconnection. I have tried all 3 cables on both USB-C ports on the Mac.
Additionally a recently completed successfully Time Machine backup fails to load back, either via TM itself or opening up the backup structure in Finder. Particularly when I try to restore/recover a ~51GB file (a virtual machine).
Of course, this looks a lot like a HW problem but I keep thinking it might be software-related.
So I decided to reach out to the community to ask if someone has observed this behaviour and, if so, what was the solution.
Thanks in advance!
