The following error message appears while importing or deleting photos from iMazing:
"Operation failed. Photos cannot be modified on your device because it is currently synced with a specific photo library, such as iPhoto or Photos"
iTunes is configured to sync your photos with the iPhoto or Photos Mac application, but needs to be configured to sync to a folder instead.
1. Set iTunes to sync Photos with a folder (not with the Photos app).
2. Sync once with iTunes to change the sync mode from 'Photos' to 'Folder'
