Can't "Unsync" photos from my iPhone - specifically the "Places" album
Hi community,
My goal:
Remove all the locally stored photos from my iPhone that were previously synced from my iMac. Why? I don't want them on there taking up space before I enable iCloud photos on the phone so i can see my photos that way instead.
The Problem:
On my iPhone, I've managed to get rid of the photo albums that were previously synced from my iMac (around 25,000 photos), but the iPhone is still showing that it has photos on it despite me having Unchecked "Sync photos to your device" in the iMac Finder iPhone Sync interface (see image below) and attempting to complete a Sync (which is an extremely temperamental process)
On my phone:
Settings > About > Photos says 5,532 photos.
Settings > About > Photos says 17GB of photo storage.
Photos app > "People and Places" section shows 8,228 photos against Places.
I have 485 photos in Recents which is all that I would expect to be stored locally on the phone + maybe a few hundred in some Shared albums (assuming they even store locally)
This doesn't really make any sense. For one thing there's misalignment between the count in the Settings app vs the Photos app Places album so that's weird. But generally It's like the phone is hanging onto a subsection of the old photos that were on the device previously but giving me no way to remove them.
I feel like the problem might be related to the syncing between iMac and iPhone via Finder which is always so hard to achieve smoothly. Every time I try to sync it gets stuck at Step 2 Preparing To Sync until I force quite the MDCrashReportTool in Activity Monitor as described here https://macreports.com/how-to-fix-finder-stuck-in-preparing-to-sync/ but then after than it will very often just go on to hang forever on Step 4 Waiting for changes to be applied
Devices:
iMac 2023 M3 chip, Sonoma 14.2.1
iPhone 15 Pro, iOS 17.2.1
I did very recently upgrade from an older iMac and an older iPhone but don't think that should be related
Many thanks for any help!
