P: File name and extension highlight when saving on macOS 10.15 Catalina

I actually found my solution to this by accident in Photoshop's own preferences. It's in file handling > append file extension. You should select never. Hope this works out for all of you going through this annoyance.

I've also experienced the same issue. I can confirm that this isn't solely an Adobe issue. I've updated to Catalina on my home setup, but not at work (Other company software we use is not compatible with Catalina). With that being said, I am only experiencing this issue along with other Save For Web issues on my iMac with Catalina installed. 

Agree that Catalina launch was when it started but other apps have found a fix in fact even other Adobe apps. Indesign does not show the extension on the file name during saves and or exports to PDF/JPG/PNG etc. so should be as simple as Ps team walking over to Id team and saying how did you do that. But the silo nature over there between products makes that an unlikely conversation.

I agree with you Ted in that it's certainly an issue that originated with the launch of Catalina. And there's certainly an argument that can be made about all the things that Catalina has screwed up. However to be fair, it's no longer an issue with any of my Microsoft products on Catalina - they not only apparently found a solution to the problem, but dedicated resources to fixing it. So, yes it originated with Catalina, but it's not something that couldn't be addressed if Adobe really wanted to address it.

Friendly reminder this is a problem with Mac OS, not Photoshop!  I have the same file name selection problem with non-Adobe programs since the Catalina update.

This just goes to show how once a company becomes so big with such proliferation into the design community, just how little they actually care about their user base. As a developer myself, the amount of actual coding time required to fix an issue like this is minimal. But like so many other software companies these days, more time is spent trying to "WOW" us with new features instead of fixing the core functionality that doesn't work. Shame on you Adobe. I've been using you since you were a 6 inch stack of 3.5 floppy discs. You have truly lost your footing with the people that made you who you are today. Perhaps we need another 2020 movement - "Photoshop Users Matter" ... maybe with enough press something would actually get done about it.

Why can't this be fixed?!

It looks like macOS Catalina 10.15.5 and Photoshop 21.2.0 did not resolve this.
The workarounds that I have been using are to either change the Format pop-up to something else and then changing it back (like Photoshop to Large Photoshop Document then back to Photoshop) or to move the text prompt with right arrow once, then left arrow four times, then shift up arrow.   Both get you to where you have just the filename selected without the ".psd".  Neither is ideal, of course. 

On my iMac that's still running macOS 10.13.6 High Sierra, it still works as expected.

I finally called Adobe yesterday about this, since the latest release (7 months into CC 2020) did nothing to address this problem.

They actually ARE aware of the issue, it's a known MacOS Catalina incompatibility, that I was told will be addressed in a future release. They then patted me on the head, gave me a cookie and said, "now run along and let us laugh behind your backs at the money we rake in while frustrating you to no end". (actually, the transcript will show that the tech simply hung up, but... Iknow what i heard.)

Only one of your Macs? That is kind of baffling. First I've heard of it not being on all Macs so I wish I could get hands on the one that works to try and figure out what makes it not a problem. Obviously people come to this thread since they are having the issue but if its not on 100% of the Macs that should make finding a fix easier for Adobe.
