[Solved] Nvida GTX 550Ti in El Capitan 10.11.2

[jsl]

I found that My MSI Nvidia GTX 550 Ti can work at 10.9.5 and 10.10.5, but not working at 10.11 or 10.11.1.

The key issues are :

1. Need set GraphicsEnabler=Yes and nvda_drv=1

2. Must use smbios=iMac 14, 2 version from Chameleon Wizard

3. Booting with nv_disable=1 to login Desktop, then install Web Nvidia Driver :

Nvidia Web Driver - 346.03.04b01 --> build 15C (see this post)  New!
