[pre-release] EFI setup for macOS Sequoia on Lenovo M73 Tiny

To resolve the issue you're facing with your EFI setup for macOS Sequoia on your Lenovo M73 Tiny, specifically with Wi-Fi not working, here's a step-by-step guide:

1. Check Wi-Fi Compatibility

• Wi-Fi Hardware: The first thing to verify is whether the Wi-Fi card in your Lenovo M73 Tiny is supported by macOS. Intel Wi-Fi cards, commonly found in PCs, often require extra drivers (kexts) like AirportItlwm.kext to work. If you're using a Broadcom card, you might need BrcmPatchRAM and AirportBrcmFixup kexts.

• Solution:

  • If you're using an Intel card, ensure that you include AirportItlwm.kext in your EFI folder and enable it in the config.plist.
  • If your card is unsupported, you might consider upgrading to a compatible Broadcom card like the BCM94360CS2, which works out of the box with macOS.

2. EFI Configuration

• Ensure that your config.plist has the correct patches and drivers for your CPU and GPU. You should check if the SMBIOS setting in your config.plist is properly configured for your hardware. For your Lenovo M73 Tiny, use a compatible SMBIOS like iMac14,4 or another one suited for Haswell-based processors.
• Check that you have the appropriate USB map or kext for your system. Issues with USB mapping can sometimes cause problems with Wi-Fi cards or other external peripherals.

3. OpenCore Troubleshooting

• Use OpenCore’s verbose mode (enabled by setting -v in boot arguments) to get more detailed information about what’s causing the boot issues.
• You can check the OpenCore logs after booting from a USB to help pinpoint what’s wrong with the current EFI configuration.

4. Patching and Kexts:

• Make sure your EFI folder contains the essential kexts, including:
  • Lilu.kext (core for many macOS functionalities)
  • WhateverGreen.kext (GPU support for AMD and Intel)
  • AppleALC.kext (audio support)
  • VirtualSMC.kext (essential for system management)

5. Lenovo M73 Specific Issues

• Since the Lenovo M73 Tiny is a less common system for Hackintosh builds, finding the right configuration may require trial and error. If you’re still facing issues with Wi-Fi or other peripherals after the initial setup, it might be helpful to consult communities like InsanelyMac or Hackintosh Zone, where others may have already tackled similar setups.

6. EFI Download:

• I noticed you provided an EFI.zip. Ensure you have the latest version of OpenCore and that your kexts and config.plist are up to date. You can check this by comparing your current files with the ones recommended in the Dortania guide.

Conclusion:

By ensuring that you have the correct kexts, appropriate patches, and verified hardware compatibility, you can resolve the issue of Wi-Fi not working on your Lenovo M73 Tiny. Additionally, troubleshooting with verbose mode and checking the logs can give more insight into what might be going wrong during boot or Wi-Fi initialization.
