Hello.  I have a 2008 Mac Pro that's been updated to 10.13.6. It has an AMD Radeon 7950 GPU which per Apple, is fully OpenGL and Metal compliant. This is confirmed by checking Apple's About this Mac and looking at the Display section under System Report.

 

Lightroom however doesn't even see the GPU as the option to turn on acceleration is grayed out. The system info profiler within LR shows the following, with GPU information conspicuously absent:

"2008 Mac Pro that's been updated to 10.13.6. It has an AMD Radeon 7950 GPU which per Apple, is fully OpenGL and Metal compliant."

 

This Apple article indicates that Mac Pros prior to mid-2010 don't support Metal:

https://support.apple.com/en-us/HT205073 

 

This Apple article seems to indicate that 2008 Mac Pro supports OpenGL 3.3:

https://support.apple.com/en-us/HT202823

 

You say that the Mac has a Radeon 7950, but the 7000 series wasn't released until 2012 -- did you upgrade your Mac Pro with an after-market card? (I didn't know that was possible.)

https://en.wikipedia.org/wiki/Radeon_HD_7000_series

 

This Adobe article indicates that if your Mac supports OpenGL 3.3 or later, it should meet the minimum system requirements for using the GPU:

https://helpx.adobe.com/lightroom-classic/kb/lightroom-gpu-faq.html 

 

However, given the age of the computer (12 years), the graphics card (8 years at least), and that you're running 10.13, your computer is ancient in "Apple years".  So it's not all that surprising that LR refuses to use the GPU.

Here's a quick snapshot of my system profiler showing support for Metal.

You can try sollution 3 in :https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html

 

But that old? hmm

 

As for that file in that direction, if you try that solution, might be better to rename or relocate it, as to get it back if that solution makes things worse.

I tried those.  No help.  The GPU option is completely grayed out:

MAC PRO,  not iMAC Pro, or MAC Book Pro, correct? 

 

I suspect a MAC PRO prior to mid 2010 will not support Metal, despite what GPU you install, I can find the following link, but not a similar one for prior to mid 2010

Hello and thanks to all who responded.

 

Yes, it is an older Mac Pro.  As mentioned, it's using an AMD 7950.  Metal is fully supported as verified by Apple's system profiler.  OpenGL 3+ is also fully supported.

 

After thinking about this issue a little more, I'm wondering if the problem lies in the fact that this computer was never compatible with 10.13.6 (High Sierra) to begin with.  The only way I was able to get this OS installed was via a software hack created by DosDude which allows the installation of newer operating systems on older hardware.  Despite the fact that this is an Intel-based system and is still very capable, this is a shining example of Apple's planned obsolescense in full effect.

 

Additionally, Adobe's requirements state that full GPU compatibility is best with OS 10.14 and higher which I cannot do unless I change the GPU in my system to an Nvidia 680 GPU.  Perhaps that's something I'll try at a later date, but was hoping to see if anyone in a similar situation to me has found a workaround.

Even if the OS provides access to a GPU via Metal or OpenGL, it still may not be compatible with LR.  LR uses GPUs in ways that are much different than video and games and frequently encounters bugs and missing functionality in the drivers. 

 

I recall reading in the feedback forum a Camera Raw engineer saying that when Camera Raw (which is built-in to LR) starts, it runs some quick tests on the GPU to test for compatibility. (I can't find that post right now.)  Given the age of your GPU and its drivers, it's very possible that it is failing those compatibility tests.
