Originally, I thought the problem was with the shell file. By viewing the contents of the file, I can verify the shell had executed. Also, I can have the shell execute a script where the output is redirect to a file. I know the shell is executing, because I can enter the exit command to terminate the shell. The problem is, when the shell is involved, no output is displayed. I intended to involve the shell by using the built-in VMware Fusion Player Boot Manager by either adding a boot option or directly booting from the shell file.
I have been coping the shell file to the EFI volume created during the Big Sur install. If this ISO file is placed in the virtual optical drive of the client virtual machine, then the UEFI Shell (v2.2) file named shell圆4.efi can be copied from the virtual optical drive. This shell does contain the setvar command.įor example, archlinux-2021.03.01-x86_64.iso file can be downloaded from Arch Linux to the host Mac. Currently, an UEFI Shell (v2.2) is available as a standalone download or as part of a package.
This command would be useful for my testing. This version of VMware Fusion Player has a built-in EFI Shell (v1.0), which does not include the setvar command. I have created a Big Sur virtual machine to do some testing, which involves modifying NVRAM variables. I am using the current free version of VMware Fusion Player (Version 12.1.0).
