Added a short section (4.) on spoofing the device ID with Clover.

Ive picked up a ATI Radeon 6870 from eBay. Can't wait for it to come. This card works in OSX from what I've seen online. Ill report back once I've had a play

Can confirm that the PowerColor ATI Radeon 6870 works perfectly fine. The 2 Mini Display, 2 DVIs & HDMI work; all 5 ports works fine in 10.11.1. Only thing I have noticed is that the fan stays throttled. I think that'ss something to do with Powermanagement in 10.11.1. I'll try more than one monitor soon and report back, but the card works fine.

Cool

I guess it won't wake after sleep like the other Radeons?

 

[VioletDragon]

Sleep doesn't work in 10.11 but I'm going to try in 10.10 also 10.9.5. I've thought about what if you roll back the drivers in 10.11? I've got a Radeon 5450 which sleep works fine with that card.

Right! So here's the problem with more than 1 monitor. 2 Monitors work fine in which either the 2 Mini Display ports or HDMI and DVI ,but anymore than 2 monitors. No signal on 3rd monitor. Guess it's a problem with the Frame Buffer in 10.11.1.

Are you using active adapters/native DP displays?

If I do everything correctly, will all the ports on a r9 390 work? I've been doing some research and I've seen a couple people say only the dvi port worked on their 390. I would like either HDMI or DP to work.

Are you using active adapters/native DP displays?

I'm using mDP Adaptors to DVI which I got from Apple awhile ago. I'll give it some time and test in 10.10.5

They are passive, you can't use them with more than 2 screens, that has nothing to do with OSX/framebuffers.
