Hey,
I have a uncommon case: the cpu core frequency is limited to 1.4 GHz instead of the possible 2.7 GHz on my "broken" MacBook Pro.
Long story:
The backlight of my 2015 MacBook Pro was broken. I ordered a broken display to exclude the cabling. Then I disassembled the MacBook because the backlight circuitry is on the back of the board. The fuse is Okay, the MosFet transistors are not visibly burned. I damaged the flex cable form the keyboard and I'm now stuck to a system running only at 1.4 GHz.
I use this old MacBook as a media server to my TV. Is there a way to override the "max cpu frequency" due to case intrusion/diagnosis failure?
Is there a utility or kernel extension to load with specific parameters to override this "security" setting (downgrade of max cpu frequency)? If the fan is not properly connected the max cpu frequency is limited to 0.9 GHz (that is unacceptable)
