I was given a mid 2010 macpro, this thing is maxed out with two solid state drive, 72gigs of ram, a bluray burner, plus a regular DVD burner. Also added are USB 3 and one HDMI output, it also has two DVI outputs. So I turn it on to install the OS, but I'm not getting any video I used the HDMI, I tried two different cables and neither works. Today I'm gonna try a DVI cable. So my question is this, do I need a driver for the HDMI cable to work? And if so will the DVI work, because they are on the same card from what I can tell. The USB 3 ports work cause the mouse I plug in is lit up. do I have to do something entirely different being the hard drives are blank. When I turned on the tower, I held down the control key to boot it. Maybe I'm over looking something, thanks in advance for everyone's help!

It sounds like you have a video card that doesn't have the Mac EFI firmware on it. I've never tried to do a clean install of OS X on a Mac Pro with this type of video card before...

Yeah I was thinking the same thing, my only hope is the DVI port works, but again I think it's on the same card

In theory, if the GPU is supported by OS X, you should see something on the screen once the OS X installer is finished loading and you can proceed with installing OS X.

If you open up the side panel and look or take out the video card, you should be able to make out what kind of GPU it is. It will also definitively tell you if all the video outputs are on the same card.

Okay I'll do that as well. I'll buy the DVI cord too. And the guy said 'all you need to do is install the OS' yeah right , I thought it's never that easy.

You need another card or another Mac for remote installation (target disk mode).
5450 can work in OS X but not with the installer. It needs patching the driver otherwise it won't work.

That's an awfully nice computer to be given for free, especially the 72GB of RAM. But it's also really strange to have included a non-mac video card, especially an HD5450, in a 2010 Mac Pro. I don't really know what to think about all that.

In any case, what you need to install the OS is a Mac video card, or at least a PC video card flashed with a Mac EFI.
