    I've had the same issue on every single beta of Big Sur (well I gave up after like beta 7 lol!) on my setup. Never any issues with Catalina. So yeah hopefully the smart folks who make OpenCore etc will come up with a fix.
  2. Synaesthesia
    Try method outlined in this post. You need working Catalina install. https://www.insanelymac.com/forum/topic/345685-big-sur-the-impossible-installaion/?do=findComment&comment=2744546

    Follow this guide But this step hdiutil create -size 12G -fs hfs+ -volname install -type SPARSEBUNDLE ~/Desktop/install You should not use 12G but 16G Been having the same problems with every version of Big Sur beta on my setup. Installation always crashes. It works through VMware method only.

    Well I’ve had the same problem on beta 1, 2,3,4, and 5 - the installer doesn’t finish and crashes. Tried a lot of things, I can install Big Sur from VMware method or restore method but not native from USB. But my system does have a quirk in that NVRAM doesn’t work in OC properly.

    You have to have the beta profile installed for the update to show up.

    You can use OCBuilder or grab a prebuilt opencore at Opencore factory, newly compiled kexts here. https://onedrive.live.com/?authkey=!APjCyRpzoAKp4xs&id=FE4038DA929BFB23!455036&cid=FE4038DA929BFB23

    Hi friend yes in the first command which reads hdiutil create -size 12G -fs hfs+ -volname install -type SPARSEBUNDLE ~/Desktop/install 12gb is not enough, for beta 3 so I used 16gb instead. Works! hdiutil create -size 16G -fs hfs+ -volname install -type SPARSEBUNDLE ~/Desktop/install Notice the difference. It's 16gb instead of 12gb. Also in the clean up commands where he says do this: hdiutil detach `diskutil list |grep 'Install macOS Beta' |awk '{print $8}'` -force I rather use command "diskutil list" to list all your disks. The one which is 12gb/16gb is the one you should detach. For me it was disk6 as you can tell here. (see attached screenshot) hdiutil detach disk6 -force I'm sure you notices your installer is probably called "Install Big Sur Beta" or something. I also use drag n drop to simplyfy matters. You can reveal the "createinstallmedia" file in finder and drag it into Terminal to avoid typing this whole command. Maybe you knew that. Good luck.

    How did you do that my friend? Do you think we could do the same for my Asus Z97-k?

    Hello I have an Asus Z97k and similar issue. NVRAM doesn’t work, eg Opencore doesn’t remember what partition it booted from last and Mac OS can’t pick a partition to reboot from in system preferences.

    Yes. Alternatively you can also download the daily build from here. https://github.com/williambj1/OpenCore-Factory/releases and new kext builds from here https://1drv.ms/f/s!AiP7m5LaOED-m-J8-MLJGnOgAqnjGw

    I assume you have a developer account with Apple.

    What error does it hang on? (Boot with -v)
  15. Synaesthesia
    No, you have to use a PCI-E graphics card for now.
