> ## Hardware:

### 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.

- 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"

However, there exists other alternatives with better WiFi and Bluetooth standards, but require additional kexts to work:

- Dell DW1820a 802.11 AC Wireless Network & Bluetooth 4.1 LE NGFF Card! Includes Revisions:

  - CV-OVW3T3
  - CN-096JNT
  - CN-0VW3T3
  - CN-08PKF4, the "CN-08PKF4" model is reported to have the most successes, so make sure to look for that specifically.

- Lenovo 00JT493 802.11 AC Wireless Network & Bluetooth 4.1 LE NGFF Card.
- Foxcon T77H649 802.11 AC Wireless Network & Bluetooth 4.1 LE NGFF Card.

### M.2 Hard Drive Replacements:

- macOS cannot be installed on the factory installed PM981 drive. Replace macOS-incompatible factory Samsung PM981 with preferably another M.2 drive.
- NVMeFix](https://github.com/acidanthera/NVMeFix) is still in its early stage. However, it has dramtically improved NVMe power management. In my personal experience, it is no longer far from SATA power consumption. I now recommend that you go with an NVMe SSD for the faster speed.
- An additional hard drive can be installed in the WAN slot. It can be used for a cleaner dual boot experience, or simply as a backup or storage drive.
