Original Question:
From what I can tell everything such as cpu (Intel Core i5-4300U, power management works), gpu (Intel HD Graphics 4400 Metal supported), WiFI and bluetooth (Intel AC7260), audio (ALC292 , used voodooHDA and it works great), battery is a work in progress, brightness works but using a tool you can use your keyboard shortcut of choice mine is brightness up = ctrl + PgUp, and brightness down = ctrl PgDn. The app I used is in the App Store Brightness Slider. Trackpad (regular using voodooPS2 acidethera's version and modding info.plist for mode 0 (disable force touch) multitouch works, camera works, iservices works though Find My has issues playing sound, and fan works through BIOS. Big Sur is not a good OS for this system unless you are very talented.
