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.
* 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.
