Hi, first, a big special thanks for your guide
Well, i have installed on my 3721 but with differences, i have begun with niresh distro, that it installs a "base" system and over mavericks, 10.9.0.
I have installed nearvy full working, sill a few issues (in To-Do list)
-Audio: changed your version to 2.8.5, without edit any, install and works.
-Graphics card: i'm using chimera (chameleon, stolen and rebranded), adding on boot "IGPEnabler=y" and works, nothing else.
-Ethernet: I download a kext (found on insanelymac, driver for realtek's rtl810x fast ethernet series). Simply works fine.
-WiFi, i replaced the wireless card, now using ar5b195, to use wifi, only did and id inyector on kext. Bluethoot, i used the firmware that u attached on your first post.
ToDo:
-Update to 10.9.5 (no real time atm)
-Have to change a bit boot flags, to can log in on icloud, Seems that is needed a Built-in ethernet, using en0. 2nd part is done (works over en0), but for first part i have to add a pair of lines on chameleon plist, or at least is what i read...
-Search and search about if our trackpad can work with Elan Touchpad.
-Add brightness control with Fn keys... (i think that for that i'll have to learn how to edit dsdt >_<)
I hope that this info can help people
