HWMonitorSMC2 VS IORegistryClone

With HWMonitorSMC2 (no reboot needed) https://github.com/CloverHackyColor/HWMonitorSMC2 I could get CPU temps and fans speed CPU frequency is not working, I guess Intel Power Gadget is needed

Try this HWMonitor2 and compare the values between them.

-HWMonitorSMC2 fan monitoring tool. It sees all fans on my system correctly. No control.

HWMonitorSMC2HWMonitorSMC2 displays all fans in my Intel hack, even in Big Sur.

First of all make sure you have a backup of your current EFI then try some patching. Then grab a copy of IOReg and open it. Search for iGPU entry and locate entry (eg. AppleIntelFramebuffer@0 in my case) with a child “display0” it controls the physical display. Select that entry (eg. AppleIntelFramebuffer@0) and on the right panel locate connector type. Then check if it’s set to “00 08 00 00” or not. (This is the connector type for HDMI). If not then. Leave it as it is (in case of laptops it is mostly 02000000). Then open your config.plist in propertree and head to DeviceProperties -> Add -> PciRoot(0x0)/Pci(0x2,0x0). Then add these entries here (Don’t touch anything already present there just add these) “framebuffer-patch-enable = 01000000”, “framebuffer-conX-enable = 01000000” and “framebuffer-conX-type = 00080000” [IMPORTANT: make sure X in conX is the number you’ll find in the ending of AppleIntelFramebuffer@ which you located previously and make sure it has a child “display0” this is important (in my case=0)] and save the config.plist and reboot. Your HDMI port should be working now. Not 100% sure about it but it works most of the time.

IORegistryClone - https://github.com/khronokernel/IORegistryClone

IORegistryClone - Utility to browse IO registry with a GUI interface, it can be useful for patching features such as CPU power management, USB mapping, etc

Do you have IORegistryExplorer ?
