Chapter 8: Post-MultiBeast tasks (Video)
As you’ve noticed, using an NVIDIA GPU means that you still have a few more steps to get it working. Here’s what I found to be successful:
1. Install the NVIDIA Web drivers that you stored in your “Other” folder. A reboot is required after install. Note that, until we do a few more tweaks, you’ll need to use nv_disable=1 @ reboot until everything is complete.
2. Download latest Clover installer – run this to update to latest version of Clover. In the process, we need to add/select
EmuVariableUefi-64.efi. Without this, the Web driver setting won’t “stick” and will always revert back to macOS driver setting.
3. Open your
config.plist in Clover Configurator. Under
System Parameters, make sure that
Inject kexts = Detect and check the box/select:
NvidiaWeb. Also click
Boot and select:
npci=0x2000. SAVE.
4. Open your
config.plist file on your new boot drive EFI, and do a text search for
CsrActiveConfig – change the variable to:
0x67 --without this, we cannot complete the next step (this disables security so you can make one final patch for NVIDIA). See this post for more info (it’s the same for Sierra):
https://www.tonymacx86.com/threads/solved-cant-disable-sip-el-capitan.176151/ (revert back to the default when you're done).
5. Because we are using iMac17,1 definition, you will get “black screen” about half-way through boot.
See Problem 4 at this link. You will
now Use Shilohh's AGDPfix - Please download the version for iMac17,1 –
AGDPfix.v1.3.zip and run.
At this point, you should now be able to boot your new system without having to use nv_disable=1. You should be able to boot completely to the desktop with out the “black screen” issue, and the NVIDIA Driver option should be selected in the NVIDIA menu in the upper-right. Ladies & gentlemen, I think we are now good to go!
