Since installing Sonoma, Preview says "The document ... could not be saved" after editing.

I scan my receipts. I then open the scanned jpg file with Preview to crop the image and save it. Since installing Sonoma on my 2020 MacBook Pro (Intel), after I crop the image, I am unable to save it. Preview gives no explanation. It just pops up a dialog saying

The document “myreceipt.jpg” could not be saved. 

This seems to happen in any directory. I don't think this is a permissions problem. The permissions for myreceipt.jpg were -rw-r--r--@. I even changed them to -rw-rw-rw-@ to no effect. (I even made the directory readable/writable to group and other -- no help.) And I applied the suggested (dubious) procedure in (The file couldn’t be saved because you do… - Apple Community) with no effect.


Suggestions?

MacBook Pro 13″, macOS 10.15

For some reason, I'm unable to edit my post. I have significant additional info:


I have confirmed that this is not a permissions issue. It may be a bug in Preview 11.0, though: When I imported the jpg file with Photos and exported it again, the exported file can then be cropped in Preview and saved.

I have always configured my scanner to take a grayscale image of receipts, and the Preview inspector says that my original scanned preview jpg file is set up for Color model: Gray, and ColorSync profile: Generic Gray Gamma 2.2 Profile.

After import/export from Photos, the resulting jpg is Color model: RGB, ColorSync profile: sRGB IEC61966-2.1.


So, perhaps Preview Version 11.0 (1056) has a bug with respect to certain JPEG color model configurations? And this has nothing to do with Sonoma, as it's quite possible I haven't used Preview since it got updated on my system on September 16, 2023.

Cerastez, are you saying that Apple responded to your feedback, and they offered that explanation? If so, it's slightly problematic: It appears that when you select "true grayscale" from the Brother iPrint&Scan, it yields sRGB IEC61966-2.1, which is indeed 8 bit, but that profile is apparently not exclusively grayscale -- though I suspect that's its primary usage.


More importantly, dropping support for a color profile, without any warning or explanation, is most certainly not a "feature". This is an extremely useful color profile, allowing you to save a lot of storage when archiving documents.


Perhaps you didn't really mean that it was a feature. It was a (presumably) intentional deprecation, which is something else entirely.
