Modify macOS CPU Performance

English | 中文

Instruction

The script is only for most 5th-10th generation CPU yet. I will try to add support for more models if needed.

The script can modify low frequency mode and energy performance preference, and use ResourceConverter.sh to generate customized CPUFriendDataProvider.kext.

By using this script, no file under the System folder will be edited. If you are not happy with the modification, just remove CPUFriend*.kext from /CLOVER/kexts/Other/ and restart.

Before install

• Read CPUFriend WARNING
• Good network
• If you have FakeCPUID argument in config.plist, this script may cause issue
• Make sure IOPlatformPluginFamily.kext untouched
• Make sure Lilu is working
• Make sure you are using correct SMBIOS model
• plugin-type=1, often injected by SSDT-PLUG or SSDT-XCPM

How to install

• Run the following command in Terminal:

bash -c "$(curl -fsSL https://raw.githubusercontent.com/stevezhengshiqi/one-key-cpufriend/master/one-key-cpufriend.sh)"

• For Clover users:

  • Copy CPUFriend.kext and CPUFriendDataProvider.kext from desktop to /CLOVER/kexts/Other/ and restart.

• For OC users:

  • Copy CPUFriend.kext and CPUFriendDataProvider.kext from desktop to /OC/Kexts/.
  • Open /OC/config.plist and add the following code into Kernel - Add:
