Apple Silicon - can't disable CPU cores and use only GPU cores

If I disable CPU only tasks in the project settings, and select only to use my Apple M4 GPU cores, the CPU cores are still running tasks.

 

Hope this can be fixed, so I can use my CPU cores for other things, and only the the iGPU for doing tasks.

You can try lowering your percentage of used cores to free up cores until you figure it out.

I thought I was wrong once, but I was mistaken.

Thanks for the response. I

Thanks for the response.

I have set processor usage to 0%, it's the same as 100%. The lowest I can go is 1%, which in reality equals 10%, cause 1 of the cores is still being fully utilized, as well as half a core for the GPU tasks, that half core is fine of course.

But if I uncheck CPU tasks in the project settings menu, that feature should work, also for other people, who don't have the time of technical skills to experiment around so much like I do.

Since only 3 BOINC projects work on Apple Silicon Macs, of course I want these to work perfectly, also since no other project has Apple Silicon GPU core support, not even Folding at home, cause Apple Silicon lacks FP64 support, sadly.
