CleanMyMac 3 messed up my photos library

I am really frustrated by what has happened here, and hope somebody can help me clean up this mess.

I bought a copy of CleanMyMac 3, hoping it could help me free up some space on my HDD. I ran a scan, and told it to clean up my Photos library. This is what CMM says it does:

Optimise photo library data: Clean out all the inside stuff that does not affect your actual photos

Remove local iCloud cache: Free your mac media you can always retrieve from iCloud

I ran that, and cleaned out a bunch of stuff, including:

- Photo cache files

- Faces cache

It seemed innocent enough, but it wasn't. Now, i'm experiencing the following symptoms (specifically regarding photos taken on my camera, and imported to the Photos library before the cleanup):

- photos taken with my camera (RAW images) do not show on screensaver

- photos taken with my camera (RAW images) do not transfer via iTunes to my IOS devices

Any photos imported after the cleanup show fine on the screensaver, and transfer to my IOS devices successfully.

Further, all photos taken with my iPhone, before or after the scan, show on the screensaver and transfer successfully.

So it's clear CMM messed up my library. I'm guessing it's one of the following:

1. It nuked the JPG versions of all the RAW images in the photos library (assuming that is what the Screensaver uses, and what iTunes transfers to IOS devices)

2. It nuked some kind of cache that is required to run the screensaver, and transfer to IOS

Their support team aren't being very helpful. They're pretending to have never heard of such an issue (surely this is not an anomaly), and suggested I restart my computer. LOL. That came after a couple of weeks of being in touch with them... love it!

Anyway, if anyone out there knows how i can force Photos to regenerate the cache or jpegs that it needs to operate correctly, that would make me super duper happy. I don't want to export and reimport all the RAW images, as i've done edits to them and don't want to lose all of that data.

I'm not storing photos in iCloud, so that's not an option either.

Thanks heaps 🙂
