| # run the following commands from a Terminal window on an M5, M5 Pro, or M5 Max: | |
| % sysctl -a | grep "machdep.cpu.brand_string" | |
| % sysctl -a | grep "hw.perflevel" | |
| % ioreg -l -b -p "IODeviceTree" -r -n "cpus" | grep "cluster-type" | |
| % ioreg -l -b -p "IODeviceTree" -r -n "cpus" | grep "logical-cpu-id" | |
| # paste the results below - thank you! |
From my M5 Pro, hope this helps!
