1. Use `xx_80_patches-v*.txt`, feel free to comment out the WWAN patches if unnecessary.
3. Remember to **dump the vanilla twice and use `diff` to make sure things were dumped properly**, store this backup somewhere safe.
4. Confirmed working `BIOS-v1.45`, I cannot be sure about other BIOS versions. Though they will most likely work as well.
5. The modded BIOS does not need to be signed by `thinkpad-eufi-sign`. 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.
6. Your BIOS chip may not be made by Winbond, but by Macronix instead. In that case, add the argument `-c MX25L12835F/MX25L12845E/MX25L12865E` to `flashrom`. See [Issue #116](https://github.com/tylernguyen/x1c6-hackintosh/issues/116#issuecomment-778654320)``

## Vanilla BIOS Settings
These BIOS settings must be made to install and run macOS without any problems:

id1[Main Menu]-->Security;
id1-->Config;
id1-->Startup;
Security-->TPM[Security Chip];
Security-->Fingerprint;
Security-->SBC[Secure Boot Configuration];
Config-->Network;

Startup-.->|CSM Support|No;

You can also disable hardware/features you do not need to save power, some examples are:

USB-->|Always on USB|Disabled;
```
### Thunderbolt 3 Settings
/// setting | Thunderbolt 3 Coldplug
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:
///
``` mermaid
graph LR
id1[Main Menu]-->Config;
Config-->id2[Thunderbolt 3];
id2-.->|Thunderbolt BIOS Assist Mode|Enabled;
id2-.->|Thunderbolt Device|Enabled;
```
/// setting | Thunderbolt 3 Hotplug
If you **DO use Thunderbolt 3 hotplug in macOS** (at the expense of idle power consumption):
///
``` mermaid
graph LR
id1[Main Menu]-->Config;
Config-->id2[Thunderbolt 3];
id2-.->|Thunderbolt BIOS Assist Mode|Disabled;
id2-.->|Security Level|id3[No Security];
id2-.->|Support in Pre Boot Environment: Thunderbolt Device|Disabled;
