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:
- NOTE: If you do have a modded BIOS firmware, please reset all settings relating to Thunderbolt 3 to default, all that's needed are settings detailed below or in [1_README-HARDWAREandBIOS.md](https://github.com/tylernguyen/x1c6-hackintosh/blob/master/docs/1_README-HARDWAREandBIOS.md)
### 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.
