Thanks for the project. I installed BigSur but Intel iGPU only take 7MB of Ram, where I installed Catalina it takes 2GB of Ram. Is there anything I need to tweak. IMG_20201230_151640

What’s your NUC model? It appears you're using a NUC7.

Your picture shows an Iris 640 instead of 655 and the memory speed is also displayed incorrectly if you are using a NUC8 but correct if you're using a NUC7. Same for the processor, it should display an i5 quad core not dual core. I think you're using a NUC7 which isn't supported by this config.

Funny it worked sort of ok in Catalina, given all the NUC8 specific ACPI patches and such. The NUC7 will run both fine though, but please don't use this config cuz it's not optimised and might cause issues in the long run.

Just did a clean install of Big Sur 11.1 on my test NUC and everything looks good.

It's because I removed the 2gb VRAM settings as the documentation states its best to not use it. So now macSO decides how much to allocate, which is 1.5gb on most systems. I think it gets reduced if you have 4gb ram and maybe increased if you got 32gb or more, not sure though.

If you want the 2gb VRAM back you will need to add a framebuffer-unifiedmem entry with as data field 00000080 to the frame buffer config.

From the WhateverGreen FAQ:

framebuffer-unifiedmem (VRAM, it is not recommended to use this patch)

I still have it in my other repo though, which reminds me to remove it there too lol.
