Change to iMac14,2
I removed all of these and changed it with iMac14,2 Board-ID but still shown NVIDIA Chip Model 7 MB.

Note: Even HD530 shown Display 7MB.

Before the playing AppleGraphicControl.kext I backup to original one. But when I install again this getting this error.

Edit: I fixed it.

I manually deleted AppleGraphicControl.kext and installed original one with KextBeast restart and its worked.

Probably I break it this kext somehow.

Hi there all;

This is my 1st post so hopefully its in the right thread - apologies if not. I need some help and it seems that this is a good place to ask!
I am trying to setup an eGPU (purchased from Bizon) on my iMac. I contacted Bizon and am awaiting their reply. But any help would be appreciated.

I have an Nvidia 980ti in the eGPU. The Bizon prefpane 'install wizard' came up with an error when it looked for a 'web driver'. So being impatient, rather than wait for Bizon to get back to me I looked for the correct Nvidia web driver for my
that it was OK to install a driver for a non-existent card... as the eGPU unit was not yet hooked up.

However on restart after install the iMac hangs about a quarter of theway into the startup progress bar. I assume this is because of driver incompatibility? I tried resetting pram (cmd-opt-p-r) but it still hangs. The only thing I can launch is OS X recovery which has only system restore options. And single-user command line. And of course I can see the drive in target disk mode from another mac. Safe mode won't boot.

Please advise what I should do - I need my computer back! Basically I'm guessing I need to uninstall the Nvidia driver - either via command line in single user mode - if any tips on that please provide a step by step as I'm not confident in messing with command line) OR by hunting down the files in target disk mode and deleting them.

My system:
iMac 27" late 2013 / 3.2 ghz / native card is NVIDIA GeForce GT 755M
Yosemite 10.10.5

Many thanks in advance for any tips,

Rory

Just 3 Step and No needs Change to any Mac type..iMac,etc
1. sudo nano /System/Library/Extensions/NVDAStartupWeb.kext/Contents/info.plist
2. Then change NVDARequiredOS to this (assuming you're indeed on 16B2333e)
<key>NVDARequiredOS</key>
<string>16BXXXX</string>(Macos build)
3. Patch with AGDPfix....Restart

Tried editing config.plist file to have web graphics.

Unable to install current nVidia drivers. Says Mac OS X version is not comparable.

Computer was working great with El Capitan.

Apple silently pushed a new build of 10.12.1 and there haven't been any new drivers for it.

So I'm out of luck until drivers are released?

With some modifications to the distribution file and to the NVDAStartupWeb.kext you can use the current one.
