problems with photos in update to Catalin 10.15.1

Hi RaganS,

It sounds like you're having trouble with Photos, and I want to help.

Try following the steps here to repair the Photos library:

How to use the Photos library repair tool - Apple Support

Let me know if that helps.

Thanks for using the Apple Support Communities.

I can't help with your issue but I don't get the error in Photos on Catalina running on 5 different Macs nor did I on Mojave. I have photos going back to 2011, including photos from 2015. I've not lost any originals.

You can send Apple feedback here: Feedback - Photos - Apple

Same problem. Photos first slows down when processing NEF files (Nikon's RAW format), then refuses to process the images after about 10-15 images. I "repaired" the library - but no effect whatsoever. Same problem persist. Frustrating ...

Meanwhile, this issue has been taken up in different discussions on this site. Apple has still not acknowledged the issue and keeps recommending to Repair the library, (cf. the first answer by Joseph_S. on Nov 17, 2019 7:27 AM), which is bogus and which tacitly admits that they have no solution, and there may be irrepairable damage due to a serious bug by Apple.

I have analyzed this error, which is characterized by the following behaviors: (1) photo is shown in lower quality than the original, (2) editing is impossible and produces the well-known error "Photos cannot load adjustments for this image", (3) it is not possible to reset the adjustments, (4) editing in any other application produces an error, and (5) exporting the unmodified original is not possible as it produces an "Unknown error (4)". Repairing the library reports success but does in fact NOT solve the problem. I have also examined the place where Photos keeps originals and the files for the affected pictures are NOT THERE ANYMORE. From these behaviors it seems that Photos has lost the original and the library is left with a low-resolution preview. Not sure why and when this bug started manifesting itself, but I noticed it first in Mojave and it persists in Catalina. It seems to affect some photos from 2015. I have not found any working solution and it is unlike that a fix can ever be found, since indeed the originals of the affected pictures cannot be found in the photoslibrary. They have simply vanished. It's time to hold Apple accountable.

I have had enough of the software that comes for free with Mac OS.

I have switched to smugmug.com as a repository for all my photos.

Now, it doesn't make movies out of my photos, it doesn't do facial recognition, But it does store everything securely. And it isn't free.

Not all but so many of my photos appear to be out of focus and I cannot believe that so many photos taken with various models of iPhone were photographed out of focus.

I think all my photos were also stored on Dropbox. Until I have the same photo in hand that is super sharp,, I cannot be certain that Apple has done anything to my originals. Maybe it is in fact me!.

Some photos are in sharp focus, and I don't think I am such a bad photographer as to shoot 80% of my subjects out of focus.

We'll see....

Not a solution at all. After successful repair, problem persists.

A restart also does not resolve the issue.

Same problem. Tried repairing the library twice and restarting the computer with no avail.

I have done this with no luck
