Setup 1.35 also does this check before loading your dsdt-modified.aml and wont load it f it doesnt pass. So I noticed that the nvidia optimus has to be disabled before booting, and there were only 2 ways: DSDT or BIOS. This c:dsdtdsdt-modified.aml must be smaller than your memory dumped dsdt.dat Check by doing a file size comparison like shown here. And because youre not entirely rebuilding a PC, this isnt a terribly complicated task. Removing the nvidia (and ati) kexts didn't help much, the OS freezes when it's requested to do an action (randomly) and windows get stuck in plain animations with transparency (still funtional, but screwed up). Installing a new, more powerful graphics card can make a world of difference when it comes to gaming on a PC. Smaller machines are lighter and easier to travel with, but bigger, heavier boxes offer the dedicated graphics cards necessary for high-end gaming. Then, I tried to use different Intel kexts, but that wouldn't have helped much, cause the bootloader would detect the nvidia card at boot and create further conflicts in the OS. Laptops, especially gaming laptops, are a study in compromises. Our buyer's guides and build guides are regularly updated to help you find the best eGPU solutions for your needs. So, the first thing that I tried was to request a bios unlock on a few forums so I could get access to the advanced options and disable the optimus. Welcome to eGPU.io, home of external graphics card community. On further research I found out that there is no way to run both at the same time or just the nvidia one on OSX. The problem is the video arhitecture ( Intel HD3000 (on CPU) and nvidia optimus 540m). Some onboard or add-in sound cards, in addition to providing analog audio output, also feature a digital S/PDIF audio output.

I own a Toshiba Satellite (Model P755-12F) and I've been trying to get Mac OS X working for quite a while with no success. 2)S/PDIF audio pass-through from your onboard or external sound card to an S/PDIF input on your graphics card which is sent along the HDMI cable.
