    X299 Big Sur Support

    I did. Many times issue comes when you’re installing a new one. It makes modification to the nvram and store data in there and reboot This emulated nvram is okay if you’re only dealing with a single volume. When you have multiple disks and multiple apfs volumes, it’s not. Because the script...

    Yeah, but it requires modifying the root partition with scripts. And that's not always doable.

    anyone got Clover to boot their Big Sur? With nvram not working with OC, I was hoping to test with clover instead.

    Are there any other ways to fix the nvram that doesn't involve using the Emulated nvram stuff that requires some scripts to run on shutdown to save the sdram content to the EFI partition?

    Yeah, it definitely used to work with earlier version of macos with clover And ever since I updated clover that use bits of OC it no longer works there either.

    Native NVRAM Available?

    Is the nvram test where you store something, reboot the only way available to test if native nvram is supported? Following an upgrade to BigSur, I went the OC way, and ever since nvram hasn't worked. Not much of a problem other than not being able to easily choose which partition will boot, and...

    Does nvram works with your ASRock x299?

    X299 Big Sur Support

    A bit puzzled, as after going away for 3 weeks (summer holidays here), booting again today and I find that I get no USB working at all (so no keyboard nor mouse). This happens with either BigSur or Catalina. It boots fine, but once booted, I can no longer log in. Any ideas what could be wrong...

    X299 Big Sur Support

    OK, more confused than ever. I tried to install Big Sur again on a new apfs container, and it's doing exactly the same as it was doing a few months ago: After rebooting to complete the installation, it reboots right after graphics starts and you start seeing the progress bar. It then moves...

    X299 Big Sur Support

    Yeah!!! So couldn't install on the separate SSD, but this will do. 3 months I've been regularly trying.

    X299 Big Sur Support

    That's correct. I install Big Sur on another disk (a spare ssd I have on my machine) I can start the usb installer, select the disk, install and it then reboots. After that I goes to start the macOS installer of the new disk, and it reboots within 2s. I haven't attempted to directly upgrade...

    There's plenty of report of people simply upgrading their existing Catalina system to big sur.

    X299 Big Sur Support

    I managed to take a photo right before it reboots: Doesnt help much at this stage. I also tried the OC folder provided by arkanis above, after only modifying the boot option to make the AMD 5700XT work, I get exactly the same outcome, immediate reboot. It's weird, I had it booting much...

    X299 Big Sur Support

    Hi. So I've made no progress ever since I tried to boot Big Sur Beta 4 back in July. In fact, I've gone backward as it no longer boots. I've updated to OC 0.6.4; upgraded all the kext and efi drivers. I can boot the installer just fine. But when I boot the install partition after the first...
