It seems to me that you are either a bit lazy or just wanting to get a cheap replacement for a real macbook for playing with it. The goal of this platform is to do some educational work in computing and especially with OSX.
If you are not able to find a fully finished an totally working solution for your Vaio, then you have to do some research by yourself. To learn, how to edid kexts and plists and how to get, edid and patch a DSDT.aml and so on is at your own.
The starting point for my Lenovo Edge E320 had been only the hardware specs. At this time I could not find a working solution for it. I had to spent much time for looking for with my given hardware working elements, reading many pages, patching kexts and dsdt.aml and so on. There had been many tries and errors til I got a my Edge up and working.
A good starting point for you to learn something about gfx is the following link: http://rampagedev.wo...er-personality/
Other aspects you can find with the forums-search or you have simply to google for them.
Until now it looks like, that you are not interested in learning something by yourself. This could be the reason for your getting very rare support.
My intention is not at all mobbing you. If it looks for you like that, I beg your pardon!
Please do not forget to share your improvments with others and give credits to people for sharing their by themselves done work!
Have fun and no harm meant!
