Developing a program that needs maximum cores. My previous Intel Mac mini used all 6 cores, according to Activity Monitor. It showed 600% cpu usage. I assumed the M2 would use twelve, but only shows 400% cpu usage in Activity Monitor, ergo, two less!

I don't recall setting a core usage parameter in Xcode.

Any ideas?

Ventura 13.3 and Xcode 14.3 up to date as of this post.

Sorry, my error. I had engineered my DispatchQueue's over two years ago. Re-engineering them uses all cores!

The OS will determine if all 12 are needed. What is happening - in your case, all 12 cores are being used proportionately at 33.3% each. http_s://eclecticlight.co/2022/02/24/cpu-percentage-is-misleading-on-m1-macs/
