Lol wtf work flow is that?
Man Mac iOS and osx are cooked af in workflows. Had a client recently run out of space on phone due to photos. Lol turns out apples sync is all or nothing. She couldn't free up space by telling iPhoto to not sync ancient ass shit, also extra iCloud storage. Can't use it while syncs on as your old phone only has 10gigs of space. Lol complete joke, told her to go rant at the local apple shop about it.
Predatory af and shite from apple. She can't even just plug phone in and strip the photos to a usb or external cus lol iPhoto/iTunes/apparently you should only do stuff how apple wants you to do stuff. Apple products are cooked af.
On and trying to find or free up space on the phone? Ahahhaha good luck, apple happily grouped 30% of the devices storage to "other apple apps" to with zero descriptors or indicators to what they were or how to delete them. Products a joke.
