REKTIMU2 Posted June 23, 2020 Share Posted June 23, 2020 it appears for the moment SampleFull.plist is required for 11.0 Big Sur however, updated EFI firmware/SMC keys are required which I can not find yet. Otherwise, the installer complains 1 Link to comment Share on other sites More sharing options...
PippoX0 Posted June 24, 2020 Share Posted June 24, 2020 From what I see , macOS Big Sur can be installed on old HFS+ volume...That’s niceI always prefer to get old HFS+ on my rig Cheers Link to comment Share on other sites More sharing options...
REKTIMU2 Posted June 24, 2020 Share Posted June 24, 2020 I was off the mark, it doesn't need full or new smc keys. Link to comment Share on other sites More sharing options...

Tony Arnold Posted June 24, 2020 Share Posted June 24, 2020 Hah. Well, I'm headed down a rabbit hole. I wonder if I could use VMware Fusion with raw disk support to do similar. Link to comment Share on other sites More sharing options...
L0rdLogan Posted June 29, 2020 Share Posted June 29, 2020 I couldn't get this to work - even with OC 0.6.0 pre-release, fails with Pre-linking the Kernel Link to comment Share on other sites More sharing options...
polkaholga Posted July 11, 2020 Share Posted July 11, 2020 (edited) I can install doing the following 1. compile latest OpenCore and nightly builds from Lilu & WEG 2. download Beta from Apple Developer 3. make USB installer with createinstallmedia 4. add vsmcgen=1 boot-args in config.plist 5. boot from USB installer 6. make vanilla install, don't install over Catalina ! 7. after 2nd stage is finished and before installer switches to boot to install destination I add to NVRAM 7C436110-AB2A-4BBB-A880-FE41995C9F82 <key>booter-fileset-basesystem</key> <data> AA== </data> <key>booter-fileset-kernel</key> <data> AA== </data> 8. second stage of installation and voila ! 9. vsmcgen=1 can be removed (in my case) have to keep the NVRAM vars, otherwise Big Sur won't boot Hope that helps Edit: atm downloading 2nd Beta (20A4300b) Edited July 12, 2020 by polkaholga 2 Link to comment Share on other sites More sharing options...

It started loading but after some seconds stopped and telling me to check my network cionnections. I then donloaded Beta 2 from developers site, that and the update itself went through without any problems. Link to comment Share on other sites More sharing options...
Professor Posted July 24, 2020 Share Posted July 24, 2020 Hey :-) I was able to install Big Sur Beta 2 with latest OpenCore 0.6.0. Create Install Media, Boot Installer, Install Big Sur everything worked very smoothly. But Big Sur Beta 3 broke this, update stops at Apple Logo, boot into installer is also not possible anymore.

If you haven't already you need to put vsmcgen=1 in boot-args. Spoiler Link to comment Share on other sites More sharing options...
Professor Posted July 24, 2020 Share Posted July 24, 2020 Thank you for the hint, eSaF. That worked, I was able to install Beta 3 from Installer. 2 Link to comment Share on other sites More sharing options...
