Advice

  • [Prevent intermittent hackintosh disconnections Thanks @Unstoppablesss] Modify System Preferences/Eneragy Saver/Power Adapter/Put hard disk to sleep when possible(modify to off)
  • Because current hibernate cannot wake up normally, in order to avoid affecting sleep, use the terminal to turn off hibernate sudo pmset -a hibernatemode 0

VoltageShift Highly dangerous

  • Advantage：Undervolt the CPU to gain more efficiency and make the machine cooler
  • Method：
    • 1.Follow BIOS_UnlockOCPM‘s readme to unlock Overclocking Performance Menu Extremely dangerous, please backup your BIOS
    • 2.Switch Advanced → Overclocking Performance Menu → Overclocking Feature → Enabled
    • 3.Undervolt in macOS with VoltageShift

YogaSMC： Experimental

  • Normal: Fan three modes switch, microphone mute, flight mode, F10 switch screen, touchpad switch hint, keyboard backlight, Fn function key switch.
  • Abnormal: the camera has a hint, but it can't be turned off, the lock function can't be used, FN + Q can't work, the keyboard backlight will be displayed incorrectly when the power is plugged in, the battery temperature can't be read out, and you can't switch the charging speed in the system.

Change DVMT and CFG Lock

You must unlock CFG Lock , otherwise, you can't use both OpenCore and Clover.
We recommend to change DVMT into 64M, there's no damage to your computer.

  • Recommend: get into hidden BIOS
    • The way to enter hidden BIOS
      • Switch off the OneKeyBattery
      • Press following buttons with your computer closed.
        • F4 → 4 → R → F → V
        • F5 → 5 → T → G → B
        • F6 → 6 → Y → H → N
        • Power on → Press F2, speed up if failed.
  • Change the following settings.
    • Advanced → Power & Performance → CPU - Power Management Control → CPU Lock Configuration → CFG Lock → Disabled
    • Advanced → System Agent (SA) Configuration → Graphics Configuration → DVMT Pre-Allocated → 64M

MacForge

  • Advantage: Add functions which are Apple Silicon only
  • Installation: run /macforge/install.command

How to make it better?

  • PrintScreen can't be used under mac. I map it to F13 and you can change the shortcut key of screenshot to F13
  • Turn on HiDPI (see HiDPI part)
