When I try to use the "select people" option, it's selecting random areas instead of the people.

Can anyone help me understand why/figure out how to fix this issue?

I'm a portrait photographer and use the "select people" mask option for all of my shoots for skin. When I've been trying to use it today it's been selecting random parts of the photo and not the people at all. I've attached a photo for reference.

Has anyone else had this issue? This is a new one for me.

This is most likely a GPU issue. Go to Preferences-Performance and turn off the use of the Graphics processor to see if that solves it. What Mac hardware (and in particular what GPU do you use?

That unfortunately did not fix it. I'm currently using macOS Sonoma and a Intel Iris Pro 1536 MB graphics processer. I will also mention that I am using a 2015 Macbook Pro, I don't know if that changes anything.

I don't know if this helps. I'm not as well versed with graphics processing (I know I probably should be)

Your graphics processor does not fit the minimum requirements. https://helpx.adobe.com/lightroom-classic/system-requirements.html

Weird! It must be because I just updated my lightroom, it worked on the last version. Well, thank you at least I know why it's not working.

[JohanElzenga]

Yes, each update increases the minimum requirements. It used to be 1.5 GB for the GPU memory, now it is 2 GB.

So is there a way for me to install the previous version of lightroom? Everything I'm seeing says that there should be a "other versions" option, but I'm not seeing it where it's supposed to be.

[JohanElzenga]

First uninstall Lightroom Classic, then click on the three dots next to the Install button. Do realise that your upgraded catalog is not downwards compatible. You will have to use the backup of the old catalog.

Thanks, looks like the option is still not there for older versions. I've tried both from adobe creative cloud and online on both safari and google chrome.

[JohanElzenga]

It should be available in the Creative Cloud app. I can see the option even without uninstalling.

Your screenshot of LrC System Info did not show your GPU Info. But another way to see that is in preferences.

Can you share a screenshot of LrC /Preferences/Performance/ ??

Also, Intel Iris Pro 1536 MB graphics processor, are you sure that the Intel is your only graphics processor in this MAC, is their also a NVIDIA GeForce GPU that the MACOS switches between?

Mind you, that NVIDIA GPU would also be very very old and under spec for LrC AI.
