P: People Masking fails on Mac (Intel)

I just got off the phone with Adobe, they tried to help remotely but failed, they said that its one of the highest priority items to work on and that it should be fixed by mid to late march

Had this issue start two days ago. Never chose to update anything because this SAME EXACT THING happened last year and the year before. Somehow without me updating anything it occurred overnight. last time I couldnt use LR for MONTHS.

It’s not a Mac problem.  I just imported three of the SAME images to Lightroom Classic on a PC to see if the problem persisted, and it absolutely did.  It’s a Lightroom problem that I did not have before now.

Ryzen AI 9 HX 370

Lightroom 15.2

I switched to my laptop in hopes that it would work there.  It does not.  People are found on about 1/3 of the images, so it does not fail every time but enough that it is breaking my editing work flow.  These photos are a set of portraits that are clearly lit with eyes pointing at the camera in each image.

​@AK_77 what happens now? Five people have gone to the trouble of registering here and reporting the error; there are surely hundreds out there who don't have the time and (like me, usually) are hoping that someone will fix it. The least Adobe could do would be to acknowledge and investigate the problem. 

Adobe is significantly more transparent about its ongoing bugs than many large companies (e.g. Apple or Nikon), but not as much as most of us would prefer.  In the Mac OS 14.4.1 issue, an Adobe employee replied to that thread after four weeks and a dozen people posting, announcing that Adobe had investigated the issue and determined it was an Apple/AMD problem:

In this thread, Adobe Community Manager ​@nikunj.m did some initial troubleshooting with you, so he/she is at least aware of this thread. Based on past history, we may not hear much more substance until/if Adobe definitively identifies this as an Adobe or Apple/AMD bug.

Again, based on past history. the more people who report a problem, the more likely Adobe will prioritize an investigation. They recognize that only a small fraction of people experiencing a problem or requesting a feature will post in this forum.

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

​@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.
