Hardware and BIOS:

PM981:

For installation on the factory drive PM981, please refer to Issue #43.

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.
