Yeah, so I am running macOS Big Sur on an Optiplex 7020 sff (i5-4690T) using the onboard graphics (HD4600). I followed the Dortania post install guide for iGPU patching but when I boot for the first 15-25 seconds the mouse and keyboard are extremely laggy. After that time period everything is normal. I am using a DP to HDMI cable and I have no dGPU installed. Any help is appreciated.
