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

He's baaaaaack! :)


I'm having trouble upgrading to Catalina.

I realize that my hardware can be problematic. However, I have Mojave running on it just fine. (Thanks, PastryChef.) TYhere have been no issues for almost a year.

My boot drive is a NVMe on the motherboard (named "OSX"). I have several removable SSDs that I clone to, that go in a rack, attached via SATA.

I can successfully boot from clones of Mojave in that configuration.

In order to not corrupt my onboard NVMe, I've been using one of those SSDs (named "bu_osx") to try to install Catalina.
I finally figured out that my NVRAM file (emulated required with this motherboard) had to specify the clone as the boot device, in order to avoid the drop-dead "prohibited" sign. (Black screen, white circle w line thru it.)

Because of that drop-dead "prohibited" during my first attempted upgrades, I took the SSD clone ("bu_osx") of my working Mojave boot, and attached it to my MacBook Pro. I used that to upgrade to Catalina. When the process finished, the MacBook successfully booted from the clone drive, so it appears that Catalina was properly installed on it.

I disconnected "bu_osx" from the laptop, and inserted it back in my main machine. I made sure that the NVRAM file on it indicated that the boot drive was "bu_osx".

I booted from it, and on the white apple screen got the "thermometer" (progress bar) which, by the time it got 2/3 way full, had slowed to a crawl. It completed, but even after 6 hours, the Catalina desktop never showed.

All my drivers and kexts are the very latest version. My Clover is 5103.

Obviously something in my working EFI for Mojave that Catalina seriously doesn't like.

I do notice that the progress bar begins seriously slowing at the point where, during a working Mojave boot, the Vega64 card tosses up a single purple line artifact. In Mojave, at that point the screen blinks black for a moment, and then returns with the logo/progress bar briefly before the desktop appears.

Trying from the Catalina drive, that blink (and the purple artifact) never happen. So perhaps Catalina's settings for the Vega are different?

Obviously, I'm fishing here, and would greatly appreciate help from someone who has a similar setup or has encountered a similar problem.

Thanks!

Please boot in verbose mode and show me where it gets stuck.

Also, have you tried the new NVRAM fix for Z390???

Please post your EFI folder.
 
Hello again. Thank you.
EFI folder attached.
OOOHHH... new NVRAM fix? Know nothing about it. Can you point me in the right direction?
verbose mode... coming soon.

Thanks.

Please see post #8734 of this thread...

Try using the Clover EFI in post #8734. Plug in your current system definition, serial, board serial, and UUID.
 
I downloaded Clover version. Thanks. (What's your opinion of OpenCore? Is it worth the switch?)

I've been using OpenCore pretty much exclusively for a few months now. It's solid. I don't know which is better between Clover and OpenCore but it seems like OpenCore is set to supplant Clover as the de facto standard so I wanted to get ahead of the game...
 
yep... working on it now.

I forgot to mention that you should delete the /EFI/CLOVER/ACPI/patched/SSDT-6-A M I (with power injection).aml file.
Also, delete the SSDT-Z390-RP05-SLOT4-TB3HP.aml file.

Use your own USB fix instead.
