Make BootPicker set 'Boot0080' in '/nvram.plist' #1043

Closed kommtzeitkonrad closed 6 months ago

kommtzeitkonrad commented 3 years ago

Booting a system without hardware NVRAM with the help of OpenDuetPkg while having AllowSetDefault, LegacyEnable, LegacyOverwrite and WriteFlash set to YES.

When using Startup Disk preference pane, boot entries are set via efi-boot-device, efi-boot-device-data and Boot0080 variables in EFI_GLOBAL_VARIABLE_GUID. These are then stored in /nvram.plist with the help of LogoutHook and boot entries are correctly auto-selected after reboot.

Pressing CTRL+Enter in Open Core boot picker only sets Boot0080 variable, which is enough, but this will only work across reboots when booting macOS equipped with installed LogoutHook. The information is obviously lost when booting any other OS.

It would be nice to have Open Core boot picker immediately updating Boot0080 in /nvram.plist when selecting any entry while pressing CTRL+Enter.

I will add the removal of nvram.plist via Reset MVRAM here as well. We will unlikely work on the feature, however.

Hi @vit9696,

I'm using Emulated NVRAM. I having issue Boot Picker screen does not select default disk. I have two disks: CatalinaHD and preboot (This is Big Sur), I'm using Startup Disk preference pane. I select disk "CatalinaHD" and Restart. But Boot Picker always select preboot. Could you please support me fix this.

Thanks, Huy

Hi @kommtzeitkonrad, I have enabled emulated nvram follow the guide. Then I saw Boot0080 exists in nvram.plist. But it still has issue. Thanks,
