P: People Masking fails on Mac (Intel)

Also having the same issue - people masking no longer detects people and my workflow is completely broken as. result.  

3.3 GHz 6-core Intel Core I5

AMD Radeon Pro 5300 4 GB

64 GB 2667 MHz DDR4 Memory

Tahoe 26.3

LR Classic 15.3

​@AK_77 regarding the current problem, it's pure speculation. Above all, the change would have had to occur between macOS 26.2 and 26.3, a minor version, which I consider highly unlikely.

More facts:

There are currently five reports in this thread of similar symptoms. All are on LR 15.2, Mac OS 26.3, and Intel Macs with AMD GPUs:

AMD Radeon Pro W5700X (2)

AMD Radeon Pro 5500 XT (2)

AMD Radeon Pro Vega II (1)

Apple never discloses when they release new graphics drivers as part of a Mac OS release, though in the past with Intel Macs, they released them through the version cycle as Nvidia and then AMD made them available. As described in the previously linked thread, that problem started with Mac OS 14.4.1, a patch release, and was fixed for most people in Mac OS 15.0.   

Thus, it's not at all "highly unlikely" that Apple released new AMD drivers in Mac OS 26.3.

LR and the Camera Raw engine don't code for specific GPUs -- they rely on the generic operating system APIs. In the past many years on this forum, when there is a problem that is limited to a particular GPU or set of GPUs from a manufacturer that doesn't appear with other GPUs, more often than not, updating to a newer version of the graphics driver makes the problem go away. 

​@AK_77 This is pure speculation!

Fact.  See this long thread:

Users on Intel Macs with AMD GPUs started reporting significant bugs with Mac OS 14.4.1. Most reported that the problems went away after updating to Mac OS 15.0.

1. Please do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

2. Attach the original file here, and we can see if the problem occurs on other installations or is specific to yours.

LRC removal tools don't work to remove people; they show "no distraction found.” I tried resetting it by using the settings to apply or remove the tools' application.  It is invian. I need help.

​@Stevie L  Metal: AMD Radeon Pro Vega II

Operating system: Mac OS 26

There are an accumulating number of reports about AMD Radeon GPUs having problems with LR 15’s People masking and perhaps other AI commands also (some of the forum content about this from the last few months is no longer available).

For over a year, LR's AI commands have been tripping over bugs in the graphics drivers for Intel Macs' Radeon 500- and 5000-series GPUs.
 
The drivers in Mac OS 15 appeared to have addressed many of the issues, but there continues to be a steady trickle of reports like yours. It looks like neither Apple nor AMD care much about fixing driver bugs for seven-year-old GPUs on a platform Apple wants to go away.

Perhaps as more people add their reports here, Adobe will use its connections and clout to get the attention of Apple and AMD.  Back with the Mac OS 14 AMD drivers, it took about six months for Apple to release new AMD drivers in Mac OS 15 that fixed the previous round of problems:

Since upgrading to LRC15.2 I also am having this issue.  This also does not in a layer opened with camera RAW filter in PS OR in LR cloud on this machine.

I use this feature all the time and it is really wreaking havoc with my work flows! 

I have tried ALL the commonly suggested resets (e.g. deleting pref files, uninstalling and reinstalling LRC15.2, deleting CR modelzoo folder, disabling GPU acceleration: NOTHING MAKES ANY DIFFERENCE).

​@cde1313 It seems like the common issue is the AMD Radeon Pro 5700 XT

...and other AMD Radeon 500 and 5000 series GPUs on Intel Macs:

​@cde1313 I am having this issue now.

Please do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

I am having this issue now. I have not had problems with this function until yesterday.
