Hi,

I'm not in a hackintosh anymore (I was a hackintosh user a few years ago), I'm using an imac (Ati Radeon HD4850) and I'm in the video editing sector (low-budget) and I wondered if someone around the community knows if there's a way of doing this:

1) Enable 10bit display support on mac os x (apple doesn't seems to care about that, even if in windows it's already available), and i.e in my case with a 10-bit monitor connected via displayport  connection, it's a shame not being able to do it natively on mac. The card, on specs should be able to support 10-bit (http://www.amd.com/u...4870-specs.aspx), as it's "Full 30-bit display processed"

2) Enable a secondary monitor (a computer display connected via DVI/HDMI/Displayport) to be "seen" as a video monitor without an I/O card/box, just attached via displayport from the imac graphic card. It'll be useful for applications that can only use a full accurate full screen preview on a video broadcast monitor, like Apple Color, FCP... Premiere CS6 can do that, but others can't, they expect a video monitor.

Thanks.

I realize that enabling 10-bit shold be almost impossible because afaik it should be done by Apple on a wide system basis. This sucks, because on windows 7 you can already do this.

The second one, having the ability of changing the "display type" to video/tv instead of a desktop monitor, anyone has any ideas?

UPDATE: I've enabled 10-bit display support on windows 7 (64 bits), under bootcamp. I've had to softmod the card and install the drivers for the Firepro V8700, and the Catalyst Control Center. Then I can enable 10-bit display, and I've checked in photoshop (I've also enable 10-bit display in the application) with a ramp 10-bit test grey psd, and boom, smooth gradient. It's available!

If anyone is interested in getting 10-bit output from the imac (late 2009) video card on windows 7 (64 bits), this is how you do it:

So, it's a driver thing. I have 10-bit support on the imac card, but only working under windows. If I can softmod (actually, trick the installer to use 9456 ID (Firepro v8700) drivers in the 944A (HD 8450) and it works, can I do something like that in Mac os X? Is there a way to trick the system and use firegl kext on the internal pcie card? I could reflash the card and change the device ID, but I don't want to if softmod is available somehow.

PLEASE?
