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

I can confirm it has worked on Intel Macs for months now!

@GoCohoe, "LRCC v12.4 on Windows 10"

(This thread is about Mac-specific issues with People masks.) Most problems with LR's AI commands are caused by older, buggy graphics drivers. Try updating your graphics driver by going directly to the manufacturer's web site:

If that doesn't help, please start a new thread and copy/paste there the entire contents of the LR menu command Help > System Info -- that will let us see exactly which versions of hardware and software LR thinks you're running.

Yeah, it works on everything but macs

LRCC v12.4 on Windows 10

1.1) deleted the mask

2) create mask based off of subject detection

result:

Expected result from the following;

Lightroom Mobile v8.4.1 on Xperia 1ii, Android 12.

steps taken:

1) create mask based off of subject detection

This is the same file and same photo, why is the mobile app doing such a better job?

I am expecting to have a starting point to add minimal refinements on a subject to streamline editing, not to make more work.

Hit reply under the comment, but the website is trash

How do you reply to a specific comment? I thought I did but it put it under the whole thread.

I couldn't agree more with this statement! This has cost me sooo much time and tears!

Fwiw, if you can migrate the photos to a PC the masks will stay and actually work

To aide in the solution I am posting my system info:

2020 iMac

3.6 GHz 10-core intel i9

AMD Radeon Pro 5700 8 GB

os 13.4.1

Experiencing the same issue and I also have a 2020 Mac. I have spent countless hours and many tears have been shed. I have so many sessions already partically edited that are now experiencing massive masking issues to the point that I will have to redo all of my batch edits and look at every image to see where mask failed or masked things incorrectly. I literally will have to cancel my trip this week to dig myself out of the hole his has put me in. I am only thankful I found this thread so I understand what the issue actually is now.
