For installation on the factory drive `PM981`, please refer to [Issue #43](https://github.com/tylernguyen/x1c6-hackintosh/issues/43). A note however, installation and upgrading on the `PM981` can be problematic and troublesome. For a smoother experience, replace it with an aftermarket NVMe. For that, refer to [dortania/Anti-Hackintosh-Buyers-Guide](https://dortania.github.io/Anti-Hackintosh-Buyers-Guide/Storage.html).
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.**
However, there exists other alternatives with better WiFi and Bluetooth standards, but additional kexts are required. See [`dortania/Wireless-Buyers-Guide`](https://dortania.github.io/Wireless-Buyers-Guide/).

* If you do not use Thunderbolt 3 hotplug in macOS (don't mind shutting down the machine to connect TB3 devices), this will drastically lower power consumption:
### A modded BIOS will allow for more optimizations to be made for macOS and will overall make your hackintosh better. I am a BIOS modding novice myself, but with these instructions, I was able to mod my x1c6 BIOS in less than one hour. I fully recommend doing this for all who think themselves capable. Furthermore, the default `config.plist` for this repository is meant to accommodate a modded BIOS with appropriate settings. If you cannot mod your BIOS or is unwilling to do so, use `config_unmoddedBIOS.plist`.
- Refer to http://paranoid.anal-slavery.com/biosmods/skylake.html
- Use `xx_80_patches-v*.txt`, I commented out WWAN patches since I do not need it.
- [@notthebee](https://github.com/notthebee) also has a useful video to follow: https://www.youtube.com/watch?v=ce7kqUEccUM
- Remember to **dump the vanilla twice and use `diff` to make sure things were dumped properly**, store this backup somewhere safe.
- Confirmed working `BIOS-v1.45`, I cannot be sure about other BIOS versions. Though they will most likely work as well.
- The modded BIOS does not need to be signed by `thinkpad-eufi-sign`. Just **remember to replace 4C 4E 56 42 42 53 45 43 FB with 4C 4E 56 42 42 53 45 43 FF on the patched BIOS.**
- The BIOS chip is located above the CPU, under the sticker shield:
### Finally, make sure to backup your pre-modded BIOS twice and compare the two to make sure that it was dumped properly. Furthermore, attempt this at your own risk, I am not responsible for any damages you may cause.
> ## Modded BIOS Settings:
The following are further optimization settings that can be figured once your BIOS is modded.
> * These settings are universally recommended optimizations for your hackintosh:
| | | >> Power & Performance | >> CPU - Power Management Control | >> CPU Lock Configuration (Last item, scroll up/down until you see it) CFG Lock `Disabled`|
* I also recommend undervolting your machine regarless of your usage, the following are stable settings for my x1c6 with `i7-8650U`, verified by stress testing with `Prime95` and `Heaven Benchmark`, your may be worse or better, please do your own testing. In addition, I suggest you repaste your machine with an aftermarket thermal paste for lower temps and a better undervolt.
* Native macOS Thunderbolt interfacing, at the expense of TB3 hotplugging on other OSes:
If macOS is your only OS on the machine, or if you only need to use Thunderbolt 3 hotplug on macOS. There is a custom modded firmware that can be flashed onto the Thunderbolt 3 controller that allows for native Thunderbolt interfacing in macOS:
* The Thunderbolt chip is located on the top right of the motherboard.
* A note before you do this, however, the modded thunderbolt firmware will still require that you disable Thunderbolt BIOS assist, so again, TB3 hotplug will come at the cost of power consumption.
* Secondly, as far as I can tell, this mod is really to make things look cleaner and more native within macOS, and doesn't have any real improvements versus the TB3 method currently in this repo.
> ## Modding the Thunderbolt 3 Controller:
The `Intel JHL6540 (Alpine Ridge 4C)` TB3 chip is labeled as `Winbond` and `W25Q80DVS` is located on the top right of the motherboard.
