Black screen after 10.12.1 -> 10.12.2 Update

[CheeseheadDave]

GA-Z170X-UD3
GTX 950

Everything was working correctly under 10.12.1. After doing the update and rebooting, I updated the Nvidia web drivers and rebooted again. Now I get the monitor going to sleep before the boot finishes.

Looking at all the guides, I seem to have my config.plist edited correctly, so I'm not sure where to go next.

This is in there:

<key>SystemParameters</key>
    <dict>
        <key>InjectKexts</key>
        <string>Yes</string>
        <key>InjectSystemID</key>
        <true/>
        <key>NvidiaWeb</key>
        <true/>

nvda_drv=1 is not set.

I'm using 17,1.
Yes, I can boot with nv_disable=1. That puts me back to flickering graphics.
I've tried running AGDPfix, but I get an error about SIP being enabled.

 

[CheeseheadDave]

Odd, because when I first set this system up, it didn't work with 14,2 but did after changing to 17,1.

Fixed. I figured out how to boot with SIP disabled and reapplied the AGDPfix. Thanks!

Hi CheeseheadDave.

Can you please explain in more detail how you fixed? I have the exact same board and an eVGA GTX 950 and abandoned installation last week after spending hours trying to get it to return from sleep (without a blank screen). Would you mind sharing your MultiBeast settings from initial install too? I bought parts from the November recommended guide.

I followed the instructions to disable SIP by modifying the Rtvariables (Using Clover configurator) then ran the AGDP fix for nVidia script.

Hi. Took another crack at this tonight. After installing the NVidia web drivers and rebooting, I'm getting the black screen. I try to use Clover's option (via spacebar) to set nv_disable (vesa mode), but it doesn't make a difference. It booted fine with that option prior to installing the web drivers.

I'm still on 10.12.1

Also, when you use MultiBeast, are you installing any kexts other than audio and network?

Also also, does it matter when you change from 14,2 to 17,1?

Thanks for any suggestions.

I am not sure how I missed this in my searching before, but I found a guide for the Z170X-UD3 board, and will start over following that:

If I understand your problem an easy way to fix this may simply be to boot with the nv_diable flag and manually delete the Nvidia drivers. Reboot with the same flag and install the correct Nvidia drivers. Reboot and all should be well.
