I bought iMac 2017 (Radeon Pro 580) few days ago and tried run Oculus Rift CV1 on Boot Camp (Windows 10 Home).

But disturbed video displayed on headset and "Your computer doesn't meet Rift's recommended specifications" message on Oculus Home.

Radeon Pro 580 is should be a "VR Ready" GPU. 
Would you tell us how to solve this issue?

Same issue here:  2017 iMac; AMD Radeon Pro 580 GPU; Intel Core i7 CPU; 16 GB RAM; 4 USB-3 Type-A ports; 2 USB-3 Type-C / Thunderbolt-3 ports.  Windows 10 via Boot Camp.  The Oculus app warns: "Your computer doesn't meet Rift's minimum specifications, which can lead to poor experience in VR."  Poor performance verified in various demos.

We went to the AMD website to look for a driver update.  Surprisingly, we can't find a driver specific to this GPU.  The only match appears to be a generic "MAC [misspelled with all caps] Graphics > Apple Boot Camp > iMac > Windows 10 - 64 Bit".  The driver release date is 4/5/2016.

Is AMD hiding a newer driver someplace?  Or is there some other non-obvious match in their download search tool?



ignore the incompatibility message - I've read a few posts where people have it running very smoothly. from what i've read of others posts, the issue seems to be generally the dongle or the cable. some people swear by one dongle over another. 

I've tried:
Moshi USBc - HDMI 4k dongle
Anker USB-C to HDMI Adapter, Supports 4K/60Hz

these both work for 5-10mins before gradually cutting out. 

And I tried the bootcampdrivers instead of the standard drivers too. no difference there. 

Oculus support has been zero help, but there is a handful of us playing on the new iMac. surely someone has the solution!!!

Try the USB-C to HDMI adaptor sold by APPLE (and manufactured by them) it works perfectly, no glitch, no flicking... stable video image. I tried 3 adaptors before getting a working one.

Have same 2017 Imac, I7 RX 580, 40 gigs of ram, went to apple store, bought apple cable USBC to HDMi, also has additional usbc, and usb port on it.
Oculas runs great, you just need to add second display, on AMD radeon tool in windows 10.
Everything plays great so far, robo recall is pretty cool, played some steam VR as well, it works great too.

I get the same message...Not sure why occulas is displaying, your computer does not meet minimum specifications, as it seems to work very well, no problems with picture droping out, flashes or anything like that.

Not sure when apple is going to do their native support, as they did the Darth Vader demo in the mac product release apple event this year.

Hi,

Did you run SteamVR Performance Test?

If that tool said "VR Ready", it might not be so much issue.

Hi! 
Just got my Anker USB-C converter to try with my iMac 2017 today with high expecations but no luck.
(Second converter so far)

In the settings screens all options are green and checked. No compatibility issues, no alert messages, everything seems fine. After the setup I'm getting the sound from headphones, light on the headset is white and stable but no visuals inside. Sometimes split second glitches happen inside the screen but nothing more. All black.

What should I do? Is Apple original converter a solution for that???
Can anyone help? Thanks.

I can confirm that the discontinued version of Apple’s USB C to HDMI adapter works flawlessly. The new model will not work.

Hi, I am writing here because it looks like there are many iMac users. I have iMac 2017 (3,4 GHz Intel i5, Radeon Pro 570 4GB, 40GB) and according to karlz28 it's working with Radeon 580 so I guess it probably should working with my iMac too, right? I just need to bought correct USB-C to HDMI adaptor. Can someone link here why is correctly working with iMac and still selling? Has anyone tried HL Alyx with iMac?

I have the same imac as you and it is impossible. Rift audio works but there is no image. Under bootcamp windows it does not detect the oculus rift as a second screen, it only lets the audio pass but not the video. I think it is not possible with our computer.

Do not spend the money on the apple adapter because it will not work, it is a hardware problem. It has to be a dedicated non-integrated graphics card.
