⚠️ This repository is not maintained anymore, I don't own a NUC9I7QNX anymore.

I love Mac OS and I use it for years. I could buy a Mac Mini M1, but I wont buy an unrepairable and unupgradable desktop computer. I expect durable computers, as much as I can.

Due to USB error on Big Sur 11.3+ and image of 11.2 hard to find, a clean installation has to be done from Catalina using EFI_INSTALL. Once installed, upgrade to Big Sur 11.3+ and use EFI.

Don't forget to add the serial number etc in both config.plist files.

The idea was to plug the wifi card on a M.2 slot and use built-in wifi card antenna with the new one. Hardware problem for the antenna: built-in cables are MMCX male and BCM94360CS2 are MHF4 (IPEX-4) female. The easiest way to have it running is to get antennas

• Broadcom BCM94360CS2 wifi card
• BCM94360CS2 to M.2 Key-M adapter
• Antennas

To prevent any trouble, you should disable built-in wifi:

• Advanced
  • Onboard Devices > WLAN: uncheck

• Built-in wifi connect on 5Ghz network but does not uses ac protocol:
  
• Speedtest:
  

• i210 ethernet (the bottom one) does not work, SmallTree causes kernel panic on Monterey (issue here)
• Broadcom BCM94360CS2 does not work: wifi card is listed in hardware but cannot be enabled

• No USB after update, to fix it:
  • Enable config.plist > Kernel > Add > USBInjectAll kext
  • Disable config.plist > Kernel > Add > USBMap kext
  • Disable config.plist > Kernel > Quirks > XhciPortLimit
