I accidentally installed 10.9.4 somehow instead of 10.9.3.. it seems like most everything works, but there are a few lingering problems:
Wifi doesn't work (no option to connect, no wifi icon on top right, etc)
White noise/static through headphone jack (I think this is known)
ALPS trackpad mildly twitchy (I think this is also known)
Graphical glitches - Everything seems to be in 16 bit color instead of full 32. Also artifacting when scrolling. I noticed when I was installing 10.9, during the setup process, as soon as it booted to the menu that included "install os x, disk utility, etc" it would be impossible to read due to smeared text across the center of the screen, although if I closed the notebook and it shut the screen off and I opened it back up, everything was cleared up and it worked fine. If I click on launchpad, the animation is like 2 frames. It seems like there is no graphic acceleration enabled. I have installed the 4400 vid driver and I have the i5 (I think 4300U). I believe I followed every step to the letter.
Everything else seems to work thus far (haven't tested LAN). Excellent guide.
NOTE: Running bios ver. A08
