pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD 6600 XT

The system hangs when the MacOS background wallpaper is already loaded and after I have entered my password. Taking a screenshot of this will probably not help. Sometimes the system still manages to bring the icons to the desktop, but most of the time not even that. In any case, neither the keyboard nor the mouse works.
In about one of ten cases it boots normally and I can work with the system.

Maybe faulty SSD?
 
I don't think it's a hardware issue. But I can't exclude it. Unfortunately I currently have no replacement for my 1TB NVMe SSD.
I actually wanted to rule out the possibility that the problem might be related to my boot configuration. Apparently I'm the only one with this particular problem.
I will reinstall MacOS and see if the problem persists or disappears.

When problems are sporadic like the way yours is, I tend to think it's hardware related.
 
@pastrychef I have been running this build (Asus ROG Strix Z370-G, 6-core i7, Sapphire Radeon RX 580) rock solid under OSX Mojave 10.14.3 and have not even bothered to upgrade to Catalina.

A problem has developed though -- A few times daily I will get a momentary screen of (black -- or grey static) on my Dell U2413 HDMI display. The screen (lost sync?) lasts for a second or two and then is back to normal. Seems an odd spontaneous behavior. I have to wonder what's going wrong? (OS? EFI? Motherboard? Video card? Bad cable? Monitor?) Since everything seems to work fine when this momentary glitch is not happening, I am tempted to think it's not specifically a hardware failure but a wonky setting.

One thing I might try to fix it is just move to a fresh Catalina install and boot from that SSD for awhile and see if that resolves it. So -- any ideas? And #2 I was wondering if the Catalina / install EFI you have linked at the start of this thread is updated and the best one to use with Catalina on this hardware? -- Thanks!

It sounds like a sync issue... Maybe try using DisplayPort or DVI cable.

Yes, Clover r5120 is current. When switching, copy/paste your Serial, Board Serial, and UUID from your old config.plist to the new one.
 
Greetings @pastrychef I've come across a kernel panic and am hoping you could offer some insight. I've been running 10.14.6 for quite a while, and the build is very stable. With Catalina maturing, I'm attempting to install 10.15.6. However, the macOS Installer is panicking. This is with an ITX board configured to use iGPU of a Coffee Lake CPU. Attached is the config.plist and panic log. Any suggestions would be greatly appreciated.

That kernel panic is caused by graphics problem. In your config.plist don't use 3E9B0007 for ig-platform-id. Use 3E9B0000 instead.

The problem seems to be resolved. After de- and reassembling all components the system boots now as expected.

Thank you! This information and some framebuffer tweaking allowed me to install 10.15.6 on my i3-8100 (iGPU) based hack.
