Can no longer enhance, saying I now have unsupported hardware?!!

Question

I have a iMAC 2023, 24GB of memory. I just denoised about 10 images back to back. And now i went to denoise and I get an error that says: UNSUPPORTED HARDWARE: Enhance requires a graphic card with Metal Support. WHAT DOES THAT MEAN!? I have the right software? And I have been denoising images for the last 12 months since upgrading to this computer?

Have you tried restarting your computer? If that does not solve it, then try resetting the preferences: https://www.lightroomqueen.com/how-do-i-reset-lightrooms-preferences/
