Stop asking for tutorials. We're nowhere close to being done yet.
Update:
Atheros WiFi driver added from 10.13, and fixed (iMacs)
USB 1.1 driver on Core 2 duo fixed (the OHCI driver was just gone) (maybe the source of kernel panic? not 100% sure)
Sound fixed on all computers
Started:
loading Nvidia gpu drivers (it's possible!)
AMD OpenGL (big breakthrough- Nvidia Fermi cards work natively without Metal already, so that is a big clue)
new LegacyUSBInjector (almost done)
Not done:
Nvidia OpenGL
instructions/installer/etc...
software update patch
Testing for bugs on all unsupported computers
Not yet:
Support for any computer which can't run High Sierra natively (i.e. that need High Sierra Patcher), including no AMD gpu patch for macpro3,1/etc, no backlight/sound/etc fixes, ...
However the following computers probably work OK because they didn't need patches in 10.13
MacBook5,1 = MacBook (13-inch, Aluminum, Late 2008)
MacBookPro5,1 = MacBook Pro (15-inch, Late 2008)
MacBookPro5,2 = MacBook Pro (17-inch, Early 2009)
MacBookPro5,3 = MacBook Pro (15-inch, Mid 2009)
MacBookPro5,4 = MacBook Pro (15-inch, 2.53GHz, Mid 2009)
MacBookPro5,5 = MacBook Pro (13-inch, Mid 2009)
MacPro4,1 [don't even need legacyusb]
Xserve3,1 [except network activity lights, but Apple broke that in 10.8]
