jotaperez Posted October 29, 2021 Share Posted October 29, 2021 Hi. I ask them a question to see if they can guide me. I have a disk with Monterey and the EFI (with OpenCore 0.7.4) is configured with a smbios imac 20.1 which is the closest to my hardware. I have another separate disk with Catalina and this disk does not appear in OC boot boot. I am aware that this happens because the SecureBootModel parameter is set to "default". How do you recommend configuring SecureBootModel so that Opencore can boot both Monterey and Catalina? Thanks! Quote Link to comment Share on other sites More sharing options...

jotaperez Posted October 29, 2021 Author Share Posted October 29, 2021 Thanks for your answer. What do these parameters do? I ask you to learn a little more about OC. Thanks! Quote Link to comment Share on other sites More sharing options...
