    ​@sirthrosturv, ​@Hot Tubs Oxfordshire, there are many reports that People masking fails on Intel Macs with Mac OS 26.3, and the evidence strongly points at a buggy AMD graphics driver released in 26.3:

    While waiting for Apple and AMD to release a fixed driver, try this workaround:

     

    ​@Hot Tubs Oxfordshire I intalled Mac OS Sequoia on an external drive (since it appears impossible to downgrade Tahoe) and people detection is no an issue when runnig Lightroom under that OS on the iMac.

    That’s further evidence it’s a bug in the Mac OS 26.3 AMD graphics driver.

    @iMac, OS version 26.6.2, with Intel 8-Core 3.8 GHz processor.

     

    Apple and AMD released a buggy graphics driver for the AMD 500- and 5000-series GPUs on Intel Macs in Mac OS 26.3, and many people have reported similar symptoms with People masks and other AI commands:

    The only known workaround is to roll back to Mac OS 26.2, which is tedious:

    Given that Mac OS 27 doesn’t support Intel Macs and that AMD stopped selling GPUs to Apple in 2020, I think it’s unlikely that Apple and AMD will release a fixed driver.

    Were you ever able to find a fix for the Ai mask? My LR Classic still will not find people,  I have the newest updates & I deleted the LR Classic and reinstalled. I found something on the Adobe website that says to go to preferences and general and enable people view under privacy but I don’t have a privacy option or anything that looks like enable people view in the preferences.

    die Personenerkennung und Maskierung innerhalb Camera RAW 18.5.0.2673 funktioniert seit einigen Updates von Photoshop nicht mehr auf meinem Mac Pro 2019 mit einer AMD Radeon Pro Vega II 32 GB Grafikkarte und Mac OS 26.6.2 sowie Photoshop Version 27.9.1, auf einem MacBook Pro M1 jedoch mit der selben MacOS und Camera Raw Version  jedoch einwandfrei. Jahrelang hat das einwandfrei funktioniert und ist ein wichtiger Teil meines Arbeitsprozesses. Momentan muss ich nur für die Maskierung auf den Apple Silikon ausweichen, was ich als ärgerlich empfinde. Ist das Absicht, den immer noch völlig ausreichend leistungsstarken Mac Pro 2019 nicht mehr zu unterstützen?

    So I haven't checked on these issue threads for a few months - I have just been letting my insanely expensive 2020 Intel Radeon iMac collect dust and editing on my Silicon MacBook… and I don’t love how users have just been able to comment “merge this thread” and it has been done, making a lot of my posting seemingly disappear and making all the replies A MESS. But what I am REALLY confused by, is how on earth is this marked ANSWERED?! 

    Personally, my Intel is still Unable to find people. I am up to Tahoe 26.6.2 and CameraRaw 18.5.0.2673. Has anyone else seen a resolution to this issue? I am just not interested in using a workaround that involves dropping that disable GPU file into some folder that we had to use a few years back when we suffered through masking issues for almost a year. I just wanted to check in and see if there was a fix I missed that is accomplished by some other method than just having up to date software and what should be a very qualified computer. (Sorry is there is another thread out there somewhere… with all the merging of threads, I wasn’t interested in wasting time trying to search.) 

    Also, I just checked in Lightroom Classic since that updated today also and same thing - no people found. I have also since scanned this thread a little bit more and just keep finding a bunch of comments that refer someone to a different thread but when you click it, it just comes back to this one.
