CobraKai Posted August 12, 2020 Share Posted August 12, 2020 hi ! I can't upgrade from Catalina to Big Sur Beta because BigSur Installer told me I must upgrade firmware my Mac and only option is install on hpf+ volume. Any idea how fixit ? BTW I use Big Sur Beta 4 on separate small ssd disk but if I start installer from this disk I can't install on my Catalina volume too. I don't know how figure it - how upgrade firmware on Hackintosh ??? Link to comment Share on other sites More sharing options...
Cyberdevs Posted August 12, 2020 Share Posted August 12, 2020 @CobraKai You need to update the SMBIOS section of your config.plist and also add run-efi-updater=No to your config under the nvram settings that might solve your problem. 1 Link to comment Share on other sites More sharing options...
