P: Saving copy not saving over jpg file

The frustrating part, at least for me, is that Photoshop will correctly overwrite files in very specific circumstances. If the file is already flattened (no layers, no alpha) or the filename contains " copy" at the end, or if you use the (very slow) "Export As..." option (which only supports certain formats.)

So even on Catalina and Big Sur, we know this "works" it just doesn't work in general.

Agree. All other Adobe applications work fine on Mac except Photoshop. I think it was that "Uh oh" moment for Photoshop programmers when Catalina and Big Sur are paving the way for M1 Macs. Something must gone very wrong on the root level of Photoshop programming language. Perhaps Adobe may need to rewrite Photoshop from scratch for however long it takes to fix this issue.

While it occurs on Catalina and Big Sur lets be careful about how we word this. This is not a MacOS issue that Apple needs to address. This is an Adobe issue that Adobe needs to address. They have figured out how to have this same issue work just fine on their other products we just can't seem to get it resolved in Photoshop.

This issue is related to Mac OS Catalina and Big Sur.  I am on Mac OS Mojave and have zero issue on this.

I switched over to Windows a few months back and the "Save As" --> "Replace" does exactly what one would expect it to.... for the last 25+years of computing.

Sorry to hear this is STILL happening on Mac. 😞

Agreed, I don't understand their reasoning for adding this "feature". Because, it seems like this is the way Adobe wants it to be... No way save/replace would go undetected for multiple years if it weren't on purpose. No way.

Unbelievable that we're still discussing this.

*Aidan Clarke this idiotic bug has been around since late 2019. What’s maddening: it’s a fundamental computer function ie save/replace we’re complaining about. Simply mind boggling Adobe acts like the current function is the new normal. 🤦🏻‍♂🤦🏻‍♂🤦🏻‍♂🤦🏻‍♂

We are latest version of Photoshop, MacOs Big Sur, its been happening for at least the last 3-4 minor updates of Adobe Photoshop's releases in recent months. Its so annoying. Have to go into root of files of directories every time and delete the old, take off the word copy, then update links manually in both Illustrator and InDesign.

To whom and what are you talking about?
