Moderators Jake Lo Posted May 7, 2021 Moderators Share Posted May 7, 2021 What SMBIOS are you using? Try adding -no_compat_check to boot arg or else change SMBIOS to MBP11,1 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 7, 2021 Administrators Share Posted May 7, 2021 Updates are not offered when running macOS with the -no_compat_check boot arg. There are 2 x pre-requisites for obtaining Big Sur update offers: the SMBIOS of a Mac model compatible/supported by Big Sur (MBP11,x minimum). a SIP value that does not enable Apple Internal; it's disabled by default and must be kept disabled (bit #5 of SIP value, see here for details). 1 Link to comment Share on other sites More sharing options...
