BIOS settings - xenophon61/Lenovo-ThinkCentre-M700-OSX-Sonoma-on-Skylake GitHub Wiki
The ones to watch for are the following:
- disabling the Serial port (as with all OSX86 machines, this is crucial)
 - IGPU should be set as the primary display, with perhaps 256Mb/Max memory
 - CSM should be ENABLED
 - WOL: does not make a difference (it does not work with my setup to provide stable sleep/wake behavior)
 - Intel Management: ENABLED
 
The rest of BIOS setup should be obvious, with the default values (e.g. AHCI storage, etc).
