    AMD Radeon Vii in macOS Mojave

    @PPC If you use Whatevergreen they are indeed not necessary but you don't need Whatevergreen for your Radeon VII. @foskvs They are not useless but necessary to get hardware acceleration for video on AMD cards. In general I prefer to add all graphics renames (HECI / MEI to IMEI, GFX0 to IGPU and PEGP to GFX0 in exactly this order) regardless if IGPU is active or not. Doesn't hurt and makes things a little easier if for whatever reason I have to enable IGPU one day. In addition, I already did see boards where GFX0 isn't removed from DSDT if IGPU is disabled. This could potentially cause issues if you only rename PEGP to GFX0 since you then have two GFX0 devices.

    PEGP to GFX0 is important as well

    @ITzTravelInTime No, this iMac uses the 9900K with IGPU. The SMBIOS is totally optimized for IGPU rendering which is a shame because IGPU is slower than RX580 encoders. Thus for Hackintoshes it is the best to turn IGPU off and use iMacPro1,1 for best performance. Otherwise encoding will be done by IGPU. @Picasso Something is wrong with your configuration then. Otherwise it would work. Please make sure you have renamed your ACPI devices properly.

    @Chanks 1st: Have you even read my post? Of course your scores are different from mine, I guess you don't know how to overclock the card on macOS. And even if your scores are low: so what?! It doesn't matter! It's just a Geekbench thing, nothing real-life related. No other benchmarks cofirm any slowdowns nor does rendering or gaming performance. @ITzTravelInTime All 2019 iMacs feature IGPUs and use them for video acceleration. The claim some models use Intel processors without IGPUs is false. The following chips are used: I3-8100, I5-8500, I7-8700, I5-8500, I5-8600, I5-9600K, I9-9900K. Correct choice for all Hackintoshes with Polaris, Vega and Radeon VII cards as of 10.14.5 is IGPU disabled + iMacPro1,1 SMBIOS.

    Geekbench is broken, scores are {censored}. Don't give a {censored} about them until Geekbench was updated. Use Luxmark, scores same or even better than Windows. Also gaming performance on macOS is great. Those crappy Geekbench scores aren't represented anywhere in real life so they really don't matter. JFYI: Vega 56 and Vega 64 suffer from the same issue on Geekbench, yet there has not been any performance loss in real-life use. Actually the opposite is the case with the new drivers. 10.14.6 B1 drivers improved performance even more. With 1100MHz HBM clock Luxmark score now is closer to 54k, Geekbench went up to almost 190k. Dirt 4 runs at a steady 60fps on max settings with 1440p or 93fps on average without Vsync.

    That's not true. Its status is deprecated but still included.

    These glitches are normal and affect most AMD cards with the beta drivers. Just a cosmetic issue, nothing to worry about. Your benchmark scores are slightly lower than mine for some reason. I ran my benchmarks at stock settings, same applies to the Vega 64 benchmarks. Geekbench currently is inaccurate, don't give a {censored} about it. I also believe that the Windows version of Geekbench has issues too. It scores 200,000 in Windows, which is the same as a Vega 64. This just can't be right since all other benchmarks scale very well. That being said, the macOS drivers for the Radeon VII are great already and better than the Vega 64 / 56 drivers. In general, Vega 56 / 64 cards run slower on macOS when it comes to OpenCL performance. The Radeon VII however scores exactly the same as on Windows here on my machine which is good to see.

    Radeon VII arrived and working well. No AGDP patch or Whatevergreen needed. PowerPlayTable modding is working as well. Did a 970mV UV and with that Dirt 4 runs at 1440p with max settings at stable 60fps (Vsync) with barely audible fans. Edit: Gaming Performance (recorded with Quick Time) Benchmarks

    Radeon VII Undervolting

    I am working on an Excel based PowerPlayTable generator for the VII as I did for the Vega 64. Still work in progress though since PPT is much more complex for Radeon VII and right now I don't have a card so have to rely on others for testing. Will get a VII soon tho.

    Intel Framebuffer patching using WhateverGreen

    Currently trying to get macOS running on a Cenava I7T All in One PC from China. Got it fully working except for graphics. Processor is an Intel Core i7-7600U. Acceleration with stable HDMI output only works with HD Graphics 520 Spoof. Using the proper HD Graphics 620 device-id and platform IDs results in the output crashing (flickering) after a couple seconds. Replugging the HDMI port fixes is for a few seconds, then starts flickering again. The biggest issue however is that the internal screen stops working once acceleration is active. I only get a picture with fake ID 0x12345678. With acceleration it goes blank and isn't even recognized by the system. Backlight turns off as well. Internal screen is attached via eDP. Tried tons of different IDs and framebuffer patches with no luck. Any idea how to get the internal eDP screen working?

    Public Beta isn't out yet, only Developer Beta. Edit: Now it is LOL

    Yup, GVA now is working again. And RX4xx / RX5xx cards work as well without any patches.

    I know this but if WEG would take care about this without adjustements it would be more convenient.

    @MaLd0n Strange what's going on there. Over at the German hackintosh-forum, nobody got acceleration working on the 10.14.5 Beta 1. Could you run a test with disabled IGPU? Apple added native support for video acceleration to the Polaris drivers, no dummy kext needed anymore. If you don't run on the iMacPro1,1 SMBIOS you need to add Whatevergreen and boot-args shikigva=32 as well as shiki-id=Mac-7BA5B2D9E42DDD94 so the correct AppleGVA parameters are used.

    And for tons of other users including me it doesn't work anymore... Actually the majority. Strange! Edit: Could you please check RX550 hardware encoders? They are now natively supported in 10.14.5. Disable your IGPU for that. If you use iMac18,2 SMBIOS you need to add Whatevergreen and those boot args: shikigva=32 und shiki-id=Mac-7BA5B2D9E42DDD94
