Hi all, I was doing a general perge of superfluous information on my Mac yesterday, which included deleting lots of photos and videos from Photos for Mac. Unfortunately, I just realised that many of the photos I deleted on my Mac are still on my iPhone, as well as many addition photos and video. I don't want to have a situation where I to have to delete them from my Mac, incase it starts syncing with my phone, when it's plugged in. Either way, what I'd really like to do, is ensure that the same content is on both my Mac and my Phone, without having to re-delete all the pics that I already deleted. Can anyone suggest the best course of action to do this? Thanks.
