I decided to create a MacBookPro8,1 out of the old Lenovo G770 HD3000 Sandy Bridge, i5-2410M with built-in WIFI AR9285, Ethernet AR8152. I’m going to make a tutorial on installing El Capitan 10.11.4 and Yosemite 10.10.5 on this machine, but it can be used for all other PCs or Laptops: HD3000, HD4000, HD4600 (Haswell), anything that’s older than those, it’s not worth it for El Capitan or Yosemite.
To install Yosemite or El Capitan, Clover boot loader is the only logical choice right now. Therefore, you need to understand the Clover boot loader thoroughly. It’s actually very simple when you understand it.
Please read and follow the video closely. If you’re using distros or any other means of installing, please don’t ask here, go to where you downloaded them and ask them. This is pure vanilla installation.
Sandy Bridge = HD3000 = Intel 2nd Generation i3-i7 start with “2” (2410M) = 0x01168086.
Ivy Bridge = HD4000 = Intel 3rd Generation i3-i7 start with “3” (3317u) = 0x01668086.
Haswell = HD4400-HD4600 = Intel 4th Generation i3-i7 start with “4” (4510u) = 0x04128086.
The best is to find out what’s in the PC or Laptops before you buy that is compatible with Yosemite or El Capitan – Don’t buy AMD or laptops that have white list on WIFI components (if you replace the different WIFI module, it won’t run – Lenovo is one of them) – Most laptops will need to have Wifi or bluetooth modules replaced to run native. The best wifi module now is AW-CE123H. – dual band and bluetooth 4.0 combo. Make sure the Ethernet is supported, it’s important for iMessage and Facetime: All Realtek 816x or Atheros 815x are supported. Wifi only Atheros9280 and 9285 are supported or Broadcom 943225 or 94352 (Google for more devices).
Extract DSDT and SSDTs from PC or Laptop with RWEverything. You need DSDT and SSDTs for patching after the OS X is loaded to work perfectly.
