Hi

I found topic in ifixit how to replace GPU card in iMacs 2011 ,my old card was Radeon now I have Nvidia GTX 880M ,I think is not working properly :/
I'm using now High Sierra 10.13.6 with nvidia drivers plus CUDA

My question is do I need to do this command to make my card working normally or not ?

To make clear I don't have clue how to overwrite Info.plist


"Start the computer in safe mode by holding shift.

Get your BoardID by running this command in terminal

echo "<result>$(ioreg -rd1 -c IOPlatformExpertDevice | awk -F'["|"]' '/board-id/{print $4}')</result>"

Open the AppleGraphicsControl Kext using this command

sudo nano /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/Info.plist

Use the arrow keys to go down until you see <key>ConfigMap</key> followed by a bunch of keys and strings.

LOOK FOR YOUR BOARD ID…

IF IT IS LISTED: Change the string to <string>none</string>

IF IT IS NOT LISTED: Add it in the same format as the ones listed.

Save the file by pressing Ctrl+O, then enter.

Exit by pressing Ctrl+X

Rebuild the kernel cache using the following two commands:

sudo kextcache -system-prelinked-kernel

AND

sudo kextcache -system-caches

Have Fun!"
