AMD/Nvidia Primary Display with AirPlay Mirroring

[susudio]

No not at all.

My 1 gig. ethernet network backbone is flat, with all my iMacs and NAS's running exclusively on ethernet with WiFi not configured on these network devices at all. ( Yes, I consider my iMacs to be network devices as well.) Even my Apple TV 4's are only connected or rather only configured for ethernet.

My Network also comprises of a number of "unmanaged" ethernet switches. Three of these switches are dual configured for ethernet as well as WiFi - in the 5 gig frequency spectrum as 2.4 gig is too interference prone. These dual configured switches are strategically placed throughout my residence in order to ensure that my iOS devices will receive a strong WiFi signal wherever I want to use any of these devices in my fairly spread out environment.

How does airplay now work ?

From the iMacs exclusively via ethernet to any one of my 2 Apple TV 4 boxes and 1 apple TV 3 box, on my network.

From any one of my iOS devices via WiFi to the nearest dual configured switch, providing the strongest WiFi signal. From there the signal continues via ethernet to the respective apple TV that should receive the airplay stream as originally designated by the iOS device.

Even handoff between my iOS devices and my iMacs work with this kind of setup.

One can also consider the three dual configured switches as locally functioning hotspots although one of these switches is also configured to function as an ADSL access point to the internet via my service provider.

Enjoy.

Sorry @toleda that I chipped in, but I thought I could assist in this instance as my scenario matches exactly what @susudio enquired about, or so I believe

Dear Henties,

Thanks, I figured out that since I don't have (and I have no plan to acquire) Apple TV, I don't deserve Airplay. ; )

But, I take delight by using Chromecast 2, which serve my purpose of mirroring even better. ; )

In case I do not misunderstand your message, once I buy Apple TV 4, I still do not have to get a Broadcom wifi card for my Hackintosh build in order to perform Airplay mirroring to that ATV, just make sure ATV and Hackintosh both stay in the same network, Correct?

My mistake; typo, fixed. HD630: 59120003

Yes.

Dear toleda

Thank you for clarifications ; ) . Will remove ssdt in EFI.

Yes from your iHack you can Airplay to your Apple TV provided both are on ethenet lan. Should you later wish to airplay from an iOS device you would have to have a WiFi to ethernet lan access point, also called hotspot.

Previously, I thought not only ATV, but iMac (acting by Hackintosh) can be a Airplay receiver...the trick is easy in PC.

By the way, I try this post mainly hope to get hardware iGPU accelerated encoding ability, so far no success for me.

Works great thank you Toleda for the great guides

Couple of questions though.

1. MacBook Pro that has iGPU and dGPU has both GPU's listed in System Profilier>Graphics/Displays because those have automatic graphics switching. On iMac there is no automatic graphics switching because there is no need to save battery so there is only dGPU on System Profilier>Graphics/Displays. My question is that is iGPU used at all on iMac with HD630 and Radeon Pro 570+?

2. With the two display guide my RX560 shows up as Radeon Pro 560, with this guide it shows up as Radeon RX 560, why is it different on the two guides?

Not relevant. The real reason is the iGPU does not support the iMac 27 5K display or external 5K displays. Intel HD graphics support 3x DP 1.2 while Thunderbolt 2 and 3 support DP 1.2 only. Result, the iMac27 (5K) uses 2x DP 1.2 display outputs to drive the internal display and another 2x DP 1.2 to support an external 5K display or 2x 4K displays.

In the case of the MacBook Pro there is a custom chip to switch graphics for performance and the iMac has a different custom chip to drive the 5K display with 2x DP 1.2 connections.

Intel designed themselves out of consideration for the iMac and MacBook Pro graphics. As of this date, Intel has not specified when Intel HD Graphics and/or Thunderbolt support DP 1.3. AMD graphics support 6x DP 1.2 displays (Eyefinity) while Nvidia supports 4x DP 1.4 displays delivering 4x DP 1.2. It is easy to why AMD is the only graphics choice for Apple's Pro requirement of 3x 5K displays.

My question is that is iGPU used at all on iMac with HD630 and Radeon Pro 570+?

AirPlay mirroring only (Intel Quick Sync), all iMac 27 (5K)

why is it different on the two guides?

Not the guides, difference is BIOS/primary display; one case, iGPU and dGPU in the other. Apple will apply it's model name, Radeon Pro, in dGPU case and present the VBIOS name, Radeon RX, in the iGPU case.

Thank you

One more. Hardware encoding doesn't work in macOS if iGPU is disabled in BIOS. How's iGPU related to hardware encoding?

Example, only the iGPU supports Quick Sync.
