Reply to How to get the number of high-performance cores on Apple Silicon?
If you still seek the answer, then you can get the Performance cores via sysctl along with: hw.perflevel0.physicalcpu OR hw.perflevel0.physicalcpu_max OR hw.perflevel0.logicalcpu OR hw.perflevel0.logicalcpu_max and for Efficiency cores: hw.perflevel1.physicalcpu OR hw.perflevel1.physicalcpu_max OR hw.perflevel1.logicalcpu OR hw.perflevel1.logicalcpu_max .logicalcpu and .logicalcpu_max are probably max threads (which is 1:1 for M1 Macs) Regards
