Installing and Configuring Orace VM on Mac

OK, after installing VM on my MAC Air, It was running slow and USB does not work at all.

This is how I configured it to run faster:

(don't forget to install "Additional Guess CD" to allow VM to run full-screen. 
1. enable 3 CPU cores or more to run VM smoothly (on i5)
2. enable 2D and 3D graphic rendering so the video will not get choppy when watching online
3. optional to enable drag and drop Or Copy to clipboard from VM to Host

And This is how I enable USB on my VM:
1. install extension pack for my VM to enable USB
2. Install the USB controller for the VM OS (if on window) to allow mounting the USB devices
*note: for my window 7 Pro, I download the 
Intel Download-Center for USB-3-0-Driver-Intel-USB-3-0-eXtensible-Host-Controller-Driver-for-Intel-7-Series-C216-Chipset-Family

Then, Restart computer would be a good idea after changing all that setting. Now my window 7 running as it should on my Macbook Air.
