P: (Mac) People masks selections are not as expected (Entire Screen or Square Area)

Agreed, telling someone to upgrade to a newer item because the manufacturer is purposely doing this is INSANE. 

@stunamii Yeah, thanks... I never bought an old Intel Mac - I dropped $5,200 on a brand new iMac in 2020. We came here looking for ACTUAL advice. 

Okay congratulations Some of us have computers that are only one year old that we can't use anymore so I'm not going to drop 1K plus on a computer when I just bought a new one two years ago

I caved in and bought an Apple Silicon Mac. Now the AI selection works like butter. AMD GPU's on Mac are pathetic. Neither company cares to keep drivers updated. Avoid buying an old Intel mac if you are a professional from this day forward.

YUP! it's gotten to the point I don't even upgrade without checking this forum.

@SweetPeaPhotog The level of anxiety it causes me is off the charts. I totally get bugs when new features are added - I really do... but it has been non-stop MAJOR issues since last April. Like, I don't need all the stupid AI features that will create a false reality - I just want to be able to apply local adjustments via masking to RAW files and open jpegs that I can actually see the image and not just a gray screen. Seems reasonable, right?! 

I love that they have things working and then suddenly they decide "let's take this away again" and we are just screwed

@johnrellis I use ACR exclusively... I only test issues in LRC before coming to this forum to post to make sure they replicate there... I've done both things you mentioned (which worked wonderfully last time) and they are not working. It's maddening because I was able to remove the disable GPU file for over a month with no issues. It's just one thing after another. 

Thank you for your responses always. 

@michelegranja, my only suggestion is to triple check that you've set Preferences > Performance > Use Grqphics Processor to Off and you've disabled LR's use of the GPU for AI masking:

I haven't seen any other reliable workarounds posted, unfortunately.

@johnrellis The issue is back AGAIN... and the workaround isnt working anymore. No people can be identified and masking in general just closes the whole program. You have been FAR more helpful than any Adobe employee has so I figured I would check with your first... any advice. 

I have tried reverting to previous versions and nothing is working. This all comes after have issues editing jpegs in PhotoShop a few days back where the images literally were not even showing up at all. That issue was fixed by dialing my version of PhotoShop back 1 version... I finished the gallery I was working on in PS and now I am back in ACR working on the next batch of RAW files and having this masking issue. (Tested it in LRC also and same issue as in ACR)
