Hi, i am new to the Hackintosh scene. I want to get a working install on my dell D620 with intel 945 video card and intel 3945 wifi. Please tell me which install will work for me with the least problems.

What install?

Well, I can only assume you mean which version of OS X to purchase. I recommend Snow Leopard because it's the best, and also the cheapest, option. Then get yourself an EmpireEFI disc and get ready to do some homework.

Right off the bat, you'll have to get another WiFi card.

If you're looking for a one-click solution that does all the work for you, I suggest you stay with Windows.
