Hello everyone,

I can't seem to disable CSM. It always displays a message with the following but I got no clue what to do with that.

Warning!!!
Device does not support UEFI Graphics output protocol.

I wanted to disable CSM in order to install OpenCore / and make my PC a Hackintosh.

Hope someone can help me out. Do I need a seperate GPU that does support this feature or is this just caused through another setting.
