I recently just upgraded my iPhone 7 to the Xr using the trade in program thru apple. but before I upgrade any of my iPhones I always back them up to my computer. I don't have enough iCloud storage nor do I want to pay for the upgraded storage. I brought my new iPhone back home and plugged it into my MacBook. upon trying to restore my new iPhone to my most recent backup, I was unable to. I was greeted with the message saying "this iPhone cannot be backed up because your old iPhone was not on the lastest iOS update." so I was forced to set up my xr as a new phone. the only thing that matters to me is the 1000+ photos and videos I had on my iPhone 7. is there any way I can view the backed up photos I have saved on my Mac?
