Resolving Wi-Fi Issues on Lenovo X230 with macOS Catalina

Wi-Fi issues on a Hackintosh, particularly on a Lenovo X230 with macOS Catalina, are often due to incompatible Wi-Fi hardware. Many Lenovo laptops, including the X230, come with Wi-Fi cards that are not supported by macOS. Here is a guide to address the Wi-Fi issue:

GUIDE STEP BY STEP:

1. Identify Wi-Fi Hardware:

   • Determine the make and model of your Wi-Fi card. Use a system information tool in Windows or Linux, or check the device physically if comfortable doing so.

2. Check Compatibility:

   • Verify if the Wi-Fi card is compatible with macOS. Most Intel Wi-Fi cards, commonly found in Lenovo laptops, are not supported natively.

3. Look for Existing Solutions:

   • Search for community-made kexts or patches that may enable support for your Wi-Fi card. Tools like itlwm for Intel Wi-Fi cards might be available.

4. Replace the Wi-Fi Card (Recommended):

   • If no solutions are available, the most reliable fix is to replace the Wi-Fi card with a model that is known to be compatible with macOS.
   • Recommended models include Broadcom BCM94352Z, BCM94360CS2, or other cards used in real Macs.

5. Use an External Wi-Fi Adapter:

   • As a temporary solution, you can use a macOS-compatible USB Wi-Fi adapter.

6. Update Your Kexts:

   • Ensure all your kexts are up to date, including any Wi-Fi kexts you may be trying to use.

7. Modify Config.plist:

   • Make any necessary changes to your config.plist file to ensure it's set up correctly for networking.

8. Clear NVRAM:

   • Sometimes, clearing NVRAM can resolve hardware detection issues. Do this by rebooting and using your bootloader's built-in NVRAM reset option.

9. Post-Installation Tools:

   • Use tools like Hackintool to diagnose issues with your hardware and kexts.

10. Seek Help from the Community:

    • If you're still having trouble, seek help from Hackintosh communities like tonymacx86, Reddit's r/hackintosh, or InsanelyMac where others may have solved similar issues.

Note: Replacing the Wi-Fi card will require you to open the laptop, which can void warranties and is done at your own risk. Always ensure you are compliant with local laws and guidelines when modifying hardware. Additionally, creating a Hackintosh is against Apple's EULA and is not supported by Apple.
