saving an edited file corrupts it

[roddyt]

I don't edit my files in PSu often, and when I do it is usually only for a quick crop. I recently edited a file, and when I saved it, the file was corrupted. The first time I did it, I selected Save Image to overwrite the file (jpg). The result in PSu when I tried to view the file was a postage stamp size white box with the text "invalid size". I tried opening the file in the Mac Finder and got this message: "The file "filename" could not be opened. It may be damaged or use a file format that Preview doesn't recognize." I had to go to my backup to replace the original .

After that I experimented, this time using "Save As Image". What I found is that the save consistently creates a corrupt jpg file when the option "Keep metadata in the file" option is checked. If I uncheck it, the file is good.

As I said, I don't edit often, and I think this may be the first time I've done so since updating to Mojave, so maybe there is a connection there?

Any thoughts on this? I'll submit it to Mantis otherwise.

Are you using the latest build?

I just tried this as well.
Altered a jpeg, Saved it to replace the original and after that it was corrupted.
Ran exiftool on ut and got this information.

I then exported a fresh jpeg from Nikon NX-D which I added to PSu, opened via Adjust and used the Save As… instead but the jpeg saved still got corrupt.
This is the output:

It appears that the first 50% of the image just is zeros.

This happened with single user:
macOS 4.3.2.1834

Hert, yes I believe I am: 4.3.2.1826, though Username appears to have a later version, I get "no new updates available" when I check.

Username, thanks for verifying that I'm not alone. I just ran exiftool on my file and I'm seeing the same error: "First 1019 kB of file is binary zeros". That is on a 2046 kB file, so it is the first 50%, same as yours.

Build 1838 is released to fix this.

Thanks Hert, it works fine now.
