# Hardware and BIOS:

> ## WiFi and Bluetooth:

Replace factory Intel WiFi module with a macOS compatible one. Make sure that the card is of M.2 form factor. I replaced it with the BCM94360CS2 card. This works out of the box without additional kexts and has been stable for me thus far.

**If your laptop did not come with WWAN, you can purchase additional antennas to add to your laptop. This is useful when using WiFi/Bluetooth cards that have 3 antennas.**

- The BCM94360CS2 module comes from the 2013 MacBook Air, supports BT 4.0 and 802.11a/g/n/ac. They run on eBay for <\$15.
- For the BCM94360CS2 to work with the x1c6, you would also need a M.2 NGFF adapter. They run for <\$10 on eBay under "BCM94360CS2 m2 adapter"
- Above is my current setup.    

However, there exists other alternatives with better WiFi and Bluetooth standards, but additional kexts are required. See [`dortania/Wireless-Buyers-Guide`](https://wifi.dortania.ml/).  

> ## BIOS Settings:

At the minimum, these BIOS settings must be made to install and run macOS without any problems:
