I got iCloud Photo turned off on my mac, and i just wanted to import my photos from my iPhone and then delete them from that device.
I got all my apps and iOS up to date.
The question is , if iCloud photo library is enabled on your iPhone, not if you are using it on your Mac.
If iCloud Photo Library is enabled on your iPhone, you cannot use the Mac to erase the photo after importing them, because the photos are stored in iCloud and only mirrored on your iPhone. Disable iCloud Photo Library on the iPhone, if you want your Mac to be able to erase the photos on import.
