camera raw mask_select subject doesn't work properly

GOOD NEWS!!!
The wait is finally over!

Yesterday I just installed Bridge 13, and yes, it is finally Apple silicon native, and yes, Adobe Camera Raw masking on objects/persons finally works as it should in native mode now.
Bonus - sweet new persons AI masking options...

Adobe - thank you, it took two years, but thank you finally 🙂

This bug is a known behaviour of "Select subject tool" in Camera Raw module under Rosetta-started-application for couple of months already, now up to version 14.4. 
You will ALWAYS get corrupted "Select subject" mask WHEN your hosting application (Bridge, Photoshop. Lightroom) will be launched in Rosetta mode.
If you are launching Camera Raw from Bridge, you are out of luck, Bridge IS STILL NOT Apple silicon native.

When you are starting Camera Raw from Photoshop or Lightroom, make sure you are NOT starting under Rosetta, and everything will be fine.

You might want to start Photoshop in Rosetta mode in case you still want to use legacy Filter/Plugins, which are not Apple silicon optimised, like for example in my case Anthropics Portrait Studio Pro, or Flaming Pear Software Flexify 2.
If you start host application natively, you will not see this legacy plugins anymore in the menus, they will not load. Then - If you start Camera Raw module, your "Select subject mask" will be corrupted.

Photoshop runs natively since March 2021, dear Adobe, could you please finally deliver Apple Silicon native Bridge as well?

Or - at least - fix this "Select subject" bug in Camera Raw called from Rosetta started applications. 

Many of us batch process files with Bridge, without need to import and catalogue everything, and all the edits will be saved in .XMP sidecar files. 

And no, opening files in Photoshop is not a solution, because you have to save copy of your edits in a another heavy separate Photoshop file, if you want to keep non destructive edits like in RAW+XMP tandem.

If using an M1 Mac, see https://community.adobe.com/t5/camera-raw-discussions/acr-select-subject-not-working-properly/td-p/12728546

I don't see anything unexpected in the mask in the 2nd screen capture. So the first is on the other machine and you've got all the same settings and preferences in sync (they match)?

It could be a GPU issue, you might try disabling or modifying those settings on the 'problem' machine (preferences>performance) and getting the spec's of the two machines would be useful too.

Hi haerank,

First off, I moved this thread over to Camera Raw because this has nothing to do with Bridge.

As far as your issue, my guess is that your MacBook is not as powerful as your desktop machine. Either the Video Card, or processor, or amount of RAM. Either way, I'm guessing and am not sure.

Meanwhile, I would suggest you right-click on your thumbnail region and set your thumbnails over to the left side to display vertically as that will significantly increase your screenspace for your images. But this suggestion has nothing to do with your issue, just a suggestion on workspace.

There is absolutely no reason to reinstall your OS or even Bridge. That is NOT a good troubleshooting step.

How does Select Subject work in Photoshop? Some images just can't easily be selected this way, unfortunately.
