I have a new Macbook Pro with Retina display and trying to get 4 monitors to work. I can get 3 to work with 2 MiniDisplayPorts and 1 HDMI. I've tried using the Plugable UGA-165 USB 2.0 and the latest drivers from displaylink 2.2 with no avail. Displaylink says the devices isn't supported on Maverick.

So I thought about rolling back to Mountain Lion and when I reboot, hold down the option key and select the USB Mac Install drive is shows as EFI Boot. I know the USB drive is setup correctly, because when I boot with a 2011 Macbook Pro, is shows up as Mac Install drive. Not EFI Boot.

Any suggestions how to get 4 monitors working with Maverick or rollback to ML.

Thank you,
