November 2021

Device is now 99% working!

Working:

• Wifi and BT Intel
• Brightness Level from preferencies and menu bar

• I2C Trackpad with Gesture
• Automatic Keyboard backlight (Can't change it like in Linux and Windows with f5)
• Sleep / Wake with Lid detection
• Battery Status (No Service Recommended Notification) & AC Adapter detection

Not working:

• Brightness keys:
  • 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 randomly.
  • Same thing for keyboard backlight, it work but there is no way to change it from keyboard or system.

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.
