Professor 6 Posted October 18, 2020 Posted October 18, 2020 Hello, I successfully installed all Betas up to Big Sur Beta 9 running OpenCore 0.6.3. Now with Big Sur Beta 10 I can't install. The Installer boots until a grey screen and then hangs. Anybody with the same problem? Is there a solution? Best regards, Professor Share this post Link to post Share on other sites

Crashed_Airplane 3 Posted October 20, 2020 Posted October 20, 2020 I found it Did you make the necessary changes in the config.plist e.g Security/SecureBootModel/ change this from Default to Disabled This solved it for me.

Professor 6 Posted October 20, 2020 Posted October 20, 2020 (edited) Hello, Thanks for the hint. I applied your hint. When Big Sur Beta 10 came out last week, it forced me to download a full installer and to install from scratch. This didn't work, I was not able to boot into the installer. Today something changed. Suddenly I was allowed to just update Big Sur Beta 9 through Softwareupdate. This worked. I am running (20A5395g) now. Thank you for answering to my post, Crashed_Airplane Edited October 20, 2020 by Professor Share this post Link to post Share on other sites
