I will never understand why "Show all filename extensions" is unchecked by default in Finder.

It's also unchecked in Windows by default - I suspect that in reality the concept of extensions probably confuses some users, who end up changing the extension and then struggle to work out how to open their saved files.

( I always prefer to see the extensions too though :) )

I'm assuming you don't use the package manager like Homebrew or MacPorts? this is where the gatekeeper will annoy the hell out of me. Apps installed via Homebrew often will encounter Gatekeeper alerts. Half of them will give the option to open it and the other half, the gatekeeper --demands-- gently ask me to put it in the Trash without the option to open it.

I use Homebrew daily. In System Preferences, I have Security & Privacy > General > Allow apps downloaded from: App Store and identified developers, and I don't remember the last time I got a Gatekeeper alert.

I have that option enabled since the first booting of my Macbook Air M1 and gatekeeper alert is still showing. And I am sure we are not using the same apps that ran into those alerts. I have Vivaldi, Alfred, AppCleaner, EasyFind, iTerm2, KeepassXC, MacPass, Keka, MediaInfo, NoMachine, Numi, OBS, odrive, Signal, Slack, TexStudio and VLC ran into those alert.

I am genuinely curious why people are singing that "I don't have that such problems in my computer!" slogan repeatedly? Some of us have that problem and just because we have the same OS and possible the same hardware didn't mean it is impossible. I wish people change that particular mindset and be aware that those problems does exist.

Windows gives you a big warning when you change the extension, which seems to me both sufficient and better than hiding the extension altogether (which, like URL hiding, is a fairly dangerous and largely unnecessary convenience)

Is there any way to turn this off only for applications? Or even just in the applications directory? I find it irrationally annoying that everything in the applications folder shows the ".app" extension.

Genuine question, does MacOS actually care about file extensions? I would guess not, though there are probably some compatibility features that will do things if they are there.

Because if they can’t reproduce, then much more likely than not, the problem is not inherent to the platform. In this case, there’s probably a deviation in config settings.

Additionally if they can’t reproduce, they can’t offer any advice or help.

It’s highly unlikely that MacOS behaves specially for your existence.

I was under the impression that unless a file contains some other metadata (most don't), that the extension is the way the OS chooses which app to use to open it.

I've learned to never underestimate users' ability to shoot themselves in the foot. People will click through any popup dialogue which might suggest that their decision to perform an action was wrong.

Yes it cares. If you rename a folder to folder.app then it will change to look and "behave" like an app. Or if you change the extension of a video file to mp3 you'll loose the icon preview.

Finder does try to help with renaming and when you try to rename a file only the filename is selected and not the extension.
