The man page of pmset states:
pmset must be run as root in order to modify any settings.
Yet I cannot find out how to alter the CPU_Speed_Limit variable. I’m not a registered Apple developer, but I have searched some of their archives with no success.
$ pmset -g therm Note: No thermal warning level has been recorded Note: No performance warning level has been recorded 2020-11-24 13:10:40 +0100 CPU Power notify CPU_Scheduler_Limit = 100 CPU_Available_CPUs = 8 CPU_Speed_Limit = 35
BACKGROUND: The reason I wish to know the answer to my question is because my MacBook Pro (15-inch, Early 2011) High Sierra 10.13.6 is throttling my CPU unnecessarily as it’s running very cool (roughly 50˚C via smcFanControl). I am running my MBP on AC power and without a battery as I’m waiting for a replacement battery from a third-party. I’m not sure if my AC adapter is an original Apple power adapter, and I’m not sure if that is affecting the SMC. I’ve cleared NVRAM and done an SMC reset (without battery), but I still have the above issue.
