I had some stability issues before installing nvidia drivers, but after that, system is really stable. The only problems I have to solve now are:
- I modified DSDT and usb 2.0 ports now work. I have to try to inject usb 3 fresco logic port, but for this I have to study the post linked by rehabman.
- I installed in /EFI/CLOVER/KEXTS/10.11 just those kexts which won't be updated with a system update. keep in mind that I changed my wifi half mini pci express wifi/BT card with another (BCM94352 HMB), so maybe you'll need something different for your system wifi / BT
- I didn't install all other kexts I used in Yosemite until now, because I'll try to make some patches to modify them on the fly. I have a perfectly working applehda.kext, for example, but I want to create a patch, so I won't need to install kexts each time. So at the moment I have no sound.
- I have an issue in shutting down. I have no idea if installing all the kexts still missing would solve the problem, or if it is somewhere else. Anyway when restarting system it restarts. When shutting down, display goes black, but keyboard stays with backlight on and system won't shut. In Yosemite I hadn't this issue.
regarding kexts, apart FakeSMC, which is last released with MultiBeast, keep in mind that I think they are way too many, and some of them are in double copy, so install at your own risk. of course avoid nvidia kexts in these packages, because they are for 10.10.1.
Have to say that, apart discovering clover, which is quite fascinating and with great potential, I have some doubts about upgrading to El Capitan, because system in Yosemite was really, really stable and enjoyable. I am curious about metal, and I certainly was able to score a little bit better in novabench for GPU. But USB 3 port not working sucks, really. So if won't be possible to solve this, I will consider just to stop at Yosemite. It is a laptop 5 years old. It still scores high in benchmarks, but in the end it served me well till now, and maybe I'll change it soon. My work has changed, my need changed as well, and I need something more portable, and more than that, with a stylus and pressure levels. So, curiosity apart, which is indeed a strong motivation, I don't see the point to need to upgrade to El Capitan right now.
Off topic, I am really curious about surface book, but I am very afraid it won't be hackintoshable, especially the GPU powered one.
I'll keep you updated in any step forward!
