Not working:

  • No idea in how i can fix. Someone has an hint? Standard patching method are not working
  • If you long press f6 and f7 they will work laggy
• Ambient Light Sensor Device
  • Even if we found the Device in DSDT table, on my unit doesn't work in vanilla Windows 11 setup. Maybe sensor isn't installed in this model. [Need confirm]

Issue:

• Airdrop:
  • Hope this will be added in AppleIntelWireless Road Map. Actually not an issue for me..
• Battery Status:
  • Percentage report is missaligned
    • Nothing critical it takes a little more to reach full capability after the system report it as 100% (WIP)
    • Just check it with the led you have beside the plug.
