I don't need SSDT nor DSDT. So, no.Are you using SSDTs or DSDT? Those can populate System Information > PCI.
What system definition are you using?
I don't know if 9-series motherboard SATA is natively supported.
Do you have any kexts for SATA?
A lot of this depends on how you have your EFI folder configured.
Hello again,Yes. The only X factor is the RX 5700 XT... I don't have any experience with that and it seems to be finicky for lots of people.
If you don't have problems installing Mojave, you can just upgrade to Catalina.
After spending a few days with the latest BIOS for my Gigabyte Z390 M Gaming and the new NVRAM fix from acidanthera, I think I finally have stability even with my RAM at 3600MHz!!
Please boot in verbose mode and show me where it gets stuck.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) and there have been no issues for almost a year.
My boot drive is a Nvme on the mobo (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 mobo) 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.
