Issues/Workarounds

• Intel Wi-Fi : Run Tools/HeliPort app at login, please check [FAQs] https://openintelwireless.github.io/itlwm/FAQ.html
• LAN-Fix-Realtek® 2.5GbE LAN : Not Connected
  • System Preferences → Network → Select your Ethernet controller. Normally it says (not connected) → Advanced → Hardware:
    • Switch from Automatically to Manually
    • Speed : 1000baseT (if doesn’t work 100baseTX
    • Duplex : full-duplex, flow-control, energy-efficient-ethernet
    • MTU : Standard (1500)
  • Command Line option : “sudo ifconfig en0 media 1000baseT mediaopt full-duplex”
• “Memory Modules Misconfigurured” when OSX has booted : change SMBIOS from iMacPro 7,1 to iMacPro 1,1
• Low FPS on gaming:
  • Changing from “uXcCAAC4BgEHALoGAQcADx9AAA==” to “uXcCAAC4BgYGBroGBgYGDzAPCQ==” in “algrey – mtrr_update_action – fix PAT” section gives pretty much better performances, but sound crackling appears when using HDMI/DP audio… https://github.com/AMD-OSX/bugtracker/issues/5. So, enable only one of these Kernel patches:
    • Shaneee – mtrr_update_action – fix PAT [my default] : Full FPS on gaming but issues using HDMI/DP audio.
    • algrey – mtrr_update_action – fix PAT : Audio works fine but you’ll get low FPS on gaming.
• Don’t have volume control when using HDMI/DP : Use MonitorControl app

How to use

1. Make your USB installer with this guide sudo /Applications/Install\ macOS\ YOUR\ VERSION.app/Contents/Resources/createinstallmedia –volume /Volumes/USB –nointeraction
2. Clone the repository and paste “BOOT” and “OC” directories into your’s pendrive “EFI” folder
3. Download GenSMBIOS to generate unique SMBIOS information. Run it and follow all steps, as the model select iMacPro1,1 5.
4. Boot it!

You CAN NOT use SMBIOS from this repository, it MUST be unique for every macOS installation
