I installed Windows 7 on my mid-2008 20" iMac the other day, and everything works fine except for two things... For one, the WiFi is crap. It's incredibly slow, and often disconnects for no reason. My bigger, more pressing issue, however, is the fact that my headphone jack doesn't work. I use this on a regular basis, and it's a huge inconvenience that it's just completely nonfunctional. I've been Googling both of these for days now to no avail. I can't seem to get them working right. If anybody could help me out, I'd be very appreciative.
