[macOS] cpu_freq() fails on arm64 about psutil HOT 6 OPEN

I will check further! Will also look into #2354 at the same time.

I think this is a relic of the VM used by GitHub (and other CI providers) that don't include the pmgr info that on-metal hardware provides.

Yeah what Daniel has pointed out in #2222 (comment) is spot on as to why this is failing.

I just booted a VM to test this and when I tried to use powermetrics it reports the exact same error. I opened the IORegistryExplorer just for fun and indeed the pmgr property is not exposed:

Any way you can explore around and see if the "voltage-states5-sram" or "voltage-states1-sram" or any "voltage-states*-sram" value exists in any key?

ioreg -k 'voltage-states5-sram' -r is empty, so it's not looking very promising.

any "voltage-states" at all?

I'm not sure "CPU Frequency" has any meaning for a VM, anyway. And in most cases, CPU Frequency has changed by the time you read the results. I think the appropriate response here is to ignore the error and return either 0 or some sane default.
