Had to enable USB3 ports.
I've finished everything - booted into my desktop however the graphics are glitchy af.
I'm trying to multibeast it but it's nearly impossible because at some point it's almost not comprehensible at all...

If you followed the guide, HD4000 should be working.

its impossible - I pretty much have like 5 seconds before everything goes grey and noisy. everything works fine in safemode however...its safe mode and I can't install anything.

I have two videocards I know my nvidia doesnt work with mac, maybe it's that?


I'm slowly trying to get all the files - it literally takes 4-5 restarts to see what I'm doing

As for the last command - I don't know what it's doing I press enter it takes 1 second then nothing happens, I don't know where the output file is

You did not provide kextcache output.
Make sure DVMT-prealloc is set to 64mb in BIOS settings.

The picture was taken with snapchat otherwise I the camera app takes 5mb pics
