Since the latest versions of Lightroom Classic and MacOS the masking of people always shows “No people found” – even on photos where it was working before.

@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.

Hi @Phil21886838qk88

Thanks for reaching out, and I'm sorry to hear you're running into this issue. I have merged all your threads into one for better visibility and avoud confusion. To help us investigate, could you please provide a few more details?

Does this happen with all photos, or only with specific images?
Are the affected photos stored locally or in cloud storage/external drives?
Could you share a sample image where People masking fails with the "No people found" message?
Is Lightroom Desktop/ web able to detect faces in the same image or does that also fail?
Have you noticed whether this started after updating to Lightroom Classic 15.5?
Could you also share your System Info? (Go to Help > System Info, click Copy, and paste the details here.)

A short screen recording showing the issue from selecting Masking > People to the "No people found" message would also be very helpful.

Looking forward to your reply.

Thanks, Srishti Bali | Community & Engagement Strategist, Digital Imaging | Adobe

Hi

It does it with all photo’s

The images are stored locally, not in the cloud or an external drive.

The selection of people is random as the attached recording will show, look at the recording of the Asian Girl.

It started prior to my 15.5 update.

I have attached recordings as requested, if you need more system info then please let me know - and how to get them

Other masks such as background and object selection work fine.

Clicking select people results in “no people found”

Hi
I am running LrC version 15.5 on a Mac - 3.8 GHz 8-Core Intel Core i7, AMD Radeon Pro 5500 XT 8 GB, MacOS Tahoe 26.6

Until recently I had no issues using the masking tool, however it no longer finds people .. it comes back with "No people found"

Any help or guidance would be most appreciated.

Thanks

Does it happen with every portrait or just this one
If you try another photo with a clear face and good lighting does People masking still say no people found, If it happens on every image then it sounds more like Lightroom isnt detecting people correctly rather than an issue with that specific photo

It does it to every photo containing people

Please do the LR menu command Help > System Info, click the Copy button in the upper right corner, and paste into your reply here, so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set. That will let us provide an exact answer without guessing.
