Just registered here to download this software,
Having some trouble getting the prebuilt binary to work. On an i5-540 with OSx 10.11.4 I did manage to make it read the registers, but writing anything (even the same value) results always in a freeze + reboot. Just interested in changing 0x1FC to disable thermal throttling.
Tried it on a couple of other computers (T9300 / OSx 10.10.5) and (i5-2557M / OSx 10.12.1) but couldn't get it to read anything, it just blurbs out "Can't get registry-entry path"
I installed the supplied kext (to both locations, just to be sure), also tried running the binary in superuser mode (although on the i5-540 it worked without any priviledges..)
Am I missing some support package on those two machines? Xcode?
Under Windows (with ThrottleStop) I managed to disable BD_PROCHOT on the i5-540, and under Ubuntu I guess it's disabled by default, but installing msr-tools and running read/write commands on 0x1FC worked without crashing.
