This is required to install (and later update as/when required) Big Sur on a supported Mac model. Press [ESC] twice to return to Clover main menu. at the Clover main menu, select the "Install macOS Big Sur" partition and press [ENTER] at Big Sur main installation screen, select Disk Utility to create & format APFS the target Big Sur disk/partition/volume. Note that installation won't work if target disk/partition/volume is formatted HFS+ exit DU and return to Big Sur main installation screen, then proceed with installation the installation process will reboot a temporary macOS installer partition to complete the installation. repeat this until the temporary partition is replaced by a final <Big Sur partition name> on Preboot entry. Each time, reboot via your USB installer and make sure to select the "config_MBP11,1" config file. when the partition <Big Sur partition name> on Preboot is displayed at Clover main menu, no need to call on the "config_MBP11,1" config file, the default one will do (MBP10,2 SMBIOS + -no_compat_check boot arg). 3) Post-installation tuning Once the finalised Big Sur installation has booted, complete the 1st boot configuration tuning Once at the desktop, mount the EFI partition of your Big Sur disk Copy the EFI folder of the E6230 Big Sur Clover pack to the mounted EFI partition You may then modify your SMBIOS info using Clover Configurator app and ensure you have unique numbers or unique combination of numbers (MLB, ROM, SystemSerialNumber and SystemUUID). Please note that, with MBP10,2 SMBIOS, Big Sur will not offer any updates because it'll be running on an unsupported platform. You'll only get updated offered if you boot with the MBP11,1 config file, MacBookPro11,1 being a supported model.
