<string>force HT enabled for High Sierra or earlier (untested)</string>

I gave this patch a try in High Sierra to see if it worked, even though it is untested. Unfortunately, it doesn't seem to (or at least, it is not reflected in System Profiler or iStat menus):

Is there anything helpful I can provide to assist?
Thanks!

@dremin Could you tell me what sysctl hw.cputhreadtype command returns?

And can you try this patch to work? (Don't use with previous ht patch)

@dremin I tested patches with High Sierra and found it is expected behavior.
Simply, "Hyper-Threading Technology" entry in System Profiler app is introduced from Mojave.

sysctl hw.cputhreadtype says hw.cputhreadtype: 1 ( means HT enabled ) with my patches , so both patches are seemed working.

Ah, I am also getting hw.cputhreadtype: 1 so it looks good here too then. Thanks!
