HOW-TO OEM unlock the Galaxy Nexus

I installed the SDK properly, as well as installed all the dev packs.... However my computer cannot locate/install the "Android 1.0" USB driver. Anyone have this issue?
 
This is the message I get when I plug in my USB while in the bootloader. I followed directions exactly. Any ideas?
 
Regarding unlocking with a Mac, I have a follow up question:

If I unlock the bootloader using a PC, will I still be able to do things on the phone (install ROMs, etc.) on my Mac? I have a PC for work and a Mac at home, so I use both at different times. Right now, I'm at work but I just got my Nexus and I want to unlock the bootloader, but I don't want to do it on a PC if it will prevent me from using my home Mac to do other things.

Please pardon my ignorance with this. The GN is my first android phone, so I'm a noob when it comes to unlocking bootloaders and all that stuff.
 
install ed ADB drivers from this location C:\Program Files (x86)\Android\android-sdk\extras\google\usb_driver (windows 7) if you dont have that location then you need to download them with SDK manager (USB Tools)

You may have to run the SDK Manager as Administrator
 
Anyone else getting "waiting for device"? Frustrated!!!

I have the dll, adb, and fastboot.exe all in the same folder and usb debugging checked...
