Looking for advice with duplicate apps in Finder Applications

Hi jeff_apple,

If those duplicate applications seen are ones that are built into macOS, you won't be able to manually delete them as you would non-built-in apps. We would suggest reinstalling macOS to remove the duplicates. Here's how: How to reinstall macOS.

It would be up to the user if you'd want to just try upgrading to an entirely new macOS first: Upgrade to macOS Monterey. That should also remove the duplicate applications as you are essentially placing an entirely new upgraded copy of macOS on the machine.

If you have more questions and need more support on this, feel free to reach out to Apple Support directly: Get Support

Best regards.

Your screenshot for the Facetime.app located in Macintosh HD/Applications has a Friday July 17, 2020 date. I notice that most or all of the "duplicates" in your Finder screenshot are also dated Friday July 17, 2020. They also appear to be the apps that are bundled with macOS which means they should only be in /System/Applications. Do you have any info about what may have been done with the Mac on that date? Was there an update, upgrade or reinstallation of macOS around that time?

Note, you should not mess around with either of those folders (even if you can get to them). Catalina & subsequent versions of macOS are very different from previous versions of macOS. There is a lot of new structure behind the scenes that is not actually the way it seems to appear in the Finder and elsewhere. System/Applications is in the read-only system volume; /Applications is in the writeable data volume. They are firmlinked together so in the Finder they appear as one.

See if you can do some further diagnosis but I suspect the only real "cure" will turn out to be wiping the hard drive and reinstalling macOS from scratch.

The apps that have the circle through them are undoubtedly incompatible with Monterey and you can remove them.

iTunes was replaced by Music & TV apps in Catalina.

iPhoto was discontinued when Catalina was released.

iWeb & iDVD were EOL'd 10 years ago. They are basically not compatible after Snow Leopard.

All the others with the circle through them are also probably 32-bit apps, incompatible w/Catalina & later.
