Install Help? Alienware Aurora R8 with RX 5700 XT - Apple Logo on USB Boot, then blank screen

[ProZak512]

Long time lurker, first time poster. Hi everybody! [waves]

I'm following this guide. I have successfully:

• Downloaded the Mac OS installer on my old MacBook Pro
• Generated a bootable USB stick
• Booted the Alienware
• Selected the Boot macOS Install from Install macOS Catalina
• Seen the black screen with Apple logo and progress bar
• Then my display goes to sleep.

I've tried a bunch of different checkboxes (rebuilding the bootable USB each time) to inject Radeon drivers, generic video, etc, nothing works.

This is my first attempt, and diligent Google searching for other Aurora R8 installs hasn't brought anything up yet.

Thanks in advance for your advice, I'd love to get this up and running.

The AMD RX5000 series of discrete GPU's require this boot argument to be added to the config.plist - agdpmod=pikera otherwise you end up with a black screen.

I guess not, just tried it that way and got the same behavior. Is there a "verbose" boot mode or a log somewhere that I can use to see what's happening?

no, should be:

<key>Arguments</key>
<string>dart=0 nv_disable=1 agdpmod=pikera</string>

no, should be:

<string>dart=0 nv_disable=1 agdpmod=pikera</string>

Hooray! That did it! Thanks, y’all, I really appreciate it.
