LoBlanc Posted January 8, 2022 Share Posted January 8, 2022 Ever since then the real iMac (Catalina) boots a while in verbose mode, even when the external disk containing OpenCore is not attached anymore. Booting the EFI partition of the iMac with ESP Mounter Pro does not show any particular OC entries. How can I boot the iMac as usually? Or in a different way: How do I ensure that no parts of the OC are left anywhere (if this can be a cause)? Of course I do not need any other boot loader because it is a real Mac with Catalina installed. Thanks for your help.
