cannot import photos from an iPhone
I recently bought a 2019 MacBookPro to replace a failing 2010 iMac. I copied all the data files from the 4TB iMac to a 3TB drive. The new drive was formatted as MacOS Extended (Journaled) with a GUID partition map, and is now connected to a 5th generation Airport Extreme so that both I and my wife can access all the files. The Photos library is about 168 GB with about 25K photos and videos.
I cannot import photos from the iPhone to the MacBook. It recognizes the phone when it is connected, although it does not always detect that it is unlocked. I can select photos to copy, select import, and the photos appear to be imported, but never appear in the Imports album or in the designated destination folder. I can import using Image Capture, but I would rather do this the normal way.
If I connect the phone to the iMac, I can still import photos to the photos library that is still on the iMac.
Any ideas on how I can fix this?
