[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

[CaseySJ]

MacOS is already installed yes, on a Samsung 970 1Tb

Okay, so you should be able to disable the Thunderbolt Hotplug SSDT from the Clover Boot Menu -- before macOS boot begins!

At the Clover Boot Menu, select Options. Under that will be an ACPI menu (if I recall correctly, but go through the various options). One of the submenus will list all SSDTs. Uncheck the Thunderbolt hot plug SSDT and then boot macOS.

Perhaps I missed it somewhere, but is there a newer method to get H.264 working? "shikigva=60" is causing a kernel panic for me on boot.

In addition, i made the bootable backup, (tested it works and is sitting unplugged inside my case).

The 2x10GBE and USB 3.2 certainly interests me.

I'd like to build a successor to the Z390 Designare that trounces the new 2019 Mac Pro in terms of price/performance. This motherboard seems like an ideal starting point, but I want to wait for Intel's 10th-gen Ice Lake processors...

For now, replace that with this:

shikigva=32
shiki-id=Mac-7BA5B2D9E42DDD94

Thanks will try that later tonight. Appreciate the help. This machine is a beast already!

Has anyone noticed a long startup time for "Activity Monitor" app? When I'm running on iMac19,1, the app takes about 5 bounces before it opens. When I switch to iMacPro1,1, the app opens immediately. Granted I'm on a different board (Z390 Aorus Pro), but curious if this is also happening on other systems and what could be causing it.

It takes exactly 5 bounces for me too when my system is lightly loaded. I'm using the reference hardware for this thread, with the exception being an i9-9900k. This is on 10.15.2 with an iMac 19,1 SMBIOS.

I generally notice more beach balls too in Catalina as opposed to Mojave (10.14.6), which I still have installed and boot into too for some use cases...

Netflix and Prime video are not working for me. Can anyone summarize what's happening with DRM? Is this an issue for everyone or just a few specific video cards?

Same issue for me

Thank you for testing that, so it seems to be across the board when using iMac19,1. I checked a couple of my real mac laptops here at home and that app opens instantly on all of them. Wonder what happens on a real iMac19,1.

I've been following the DRM thing on a few different threads and sites. It looks like those running Vega and newer are not having the issue. Those that are running Polaris RX 4xx-5xx cards seem to be most affected. DRM works in most places (sometimes requiring weg boot arguments) but you can get TV app, iTunes working. The problem is with DRM in Safari with sites like Netflix/Prime, and it looks like the WEG team is aware of it and working on it.

If I'm on iMacPro1,1 SMBIOS, the machine will completely lock up when trying to visit these sites in safari. On iMac19,1 headless, the site will give an error but not lock up the machine.

I already tried with no SSDT at all and I have the same lines.
