BIOS Configuration

Recommend you should Load Optimized Default first. Then save and restart and go to BIOS again.

Tweaker:

• Extreme Memory Profile: Profile 1
• Advanced CPU Settings:
  • Hyper-Threading Technology: Enabled
  • Intel Turbo Boost Technology: Auto (not the 3.0 one)

• Advanced Memory Setting:

  • Memory Enhancement Setting: Enhanced Performance

• Advanced Voltage Settings > CPU/VRM Settings:

  • CPU Vcore Loadline Calibration: Low

Settings:

• Platform Power:

  • ErP: Disable
  • Power Loading: Enabled

• IO Ports:

  • Initial Display Output: PCIe 1 Slot

  • Above 4G Decoding: Enabled

  • Above 4G MMIO BIOS assignment: Disabled (Will cause the issue with 2nd sleep)

  • Super IO Configuration → Serial Port: Disabled (Will cause the issue with Apple Watch unlock)

  • USB Configuration:

    • XHCI Hand-off → Enabled
    • Legacy USB Support → Enabled
    • USB Mass Storage Driver Support → Enabled

• Secure Boot: Disabled (Secure Boot will be disabled by default, but good to check)

USB Mapping

• USB Map is done by SSDT-USBP.aml. Can be used for AX motherboard with Intel wireless card.

CPU Power Management

• CPU power management is handled with CPUFriend and CPUFriendDataProvider for SMBIOS MacPro7,1. If you have CPU Geekbench score is lower than me, please check your BIOS configuration. If BIOS is correct, the single score and multi score almost should be liked the result picture.

iService

• To use iMessage and other Apple services, you need to generate your own serial numbers. This can be done using CorpNewt's GenSMBIOS. Make sure model is MacPro7,1. Then, go Apple Check Coverage page to check your generated serial numbers. If the website tells you that the serial number is not valid, that is fine. Otherwise, you have to generate a new set.

• Next you will have to copy the following values to your config.plist:

  • Serial Number -> PlatformInfo/Generic/SystemSerialNumber.
  • Board Number -> PlatformInfo/Generic/MLB.
  • SmUUID -> /PlatformInfo/Generic/SystemUUID. Reboot and Apple services should work.

• If they don't, follow this in-depth guide. It goes deeper into ROM, clearing NVRAM, clearing Keychain (missing this step might cause major issues), and much more.

macOS Sonoma and Sequoia Wireless

Note: This guide is for Apple wifi card only. For Intel wifi card, please check OpenIntelWireless repo for more information.

• Preparation:

  • OpenCore is the latest version.
  • Download these kexts here: https://cdn.discordapp.com/attachments/496510149658279939/1271822412865998999/IO80211Legacy.zip?ex=66b8bc6c&is=66b76aec&hm=7a575c7d31f6aa5c0fc68fb5304fa1db1ca8e1d385a7c02d4b0d41371d10f183&
  • Extract .zip file and put 2 kexts to OC/Kexts folder.
  • Open config.plist and snapshot one time.
    • System Integrity Protection is set to 0x803
      • csr-active-config | Data | 03080000
    • AMFI is disabled
      • Using AMFIPass.kext
    • SecureBootModel is set to Disabled.
    • Kernel > Block:
      • Identifier: com.apple.iokit.IOSkywalkFamily
      • Comment: Allow IOSkywalkFamily Downgrade
      • Enabled: True
      • Strategy: Exclude
      • MinKernel: 23.0.0 (Important, apply from Sonoma)
    • Make sure IOSkywalk.kext and IO80211FamilyLegacy.kext and its child AirPortBrcmNIC.kext are injected. Also, set all MinKernel to 23.0.0 (apply from Sonoma).
  • Restart the machine.

• Installation:

  • Download the latest version of OpenCore Legacy Patcher.
  • Copy OCLP to Application folder and run it.
  • If everything is correct, you can click the Post-Install Root Patch button to start patching.

• Finish
  • Then restart the machine. The wifi should be worked. If not, try to reset NVRAM and reset network settings. You can follow here for the network reset guide.

CPU Topology Rebuild

• -ctrsmt boot arg makes E-Cores to be recognized as the 3-way SMT logical threads of the P-Cores. That means with my i7-12700F, I will have 8 cores and 20 threads on macOS. This boot-arg can fix Xcode app building.
