I wonder how the "seamlessly drag and drop files, photos, and videos between your iPhone and Mac" will work. Right now, if you just want to grab the raw files of your photos and videos and not deal with the Photos app, your best bet is Image Capture, a 20+ year old seemingly unmaintained program that seems to glitch out disturbingly frequently. I really hope they can introduce something that seamlessly lets you drag…
I frequently just airdrop stuff between my iphone and mac, that's the best thing coming from android, that and pasting text between devices, eg iban, passwords, etc.
Well worth checking out.
