 The idea is to let you quickly set some useful nvram values which would normally require booting all the way into macOS recovery.
 
 Features:
 
- - You can very quickly do the equivalent of `csrutil enable/disable` (Big Sur or Catalina settings).

- - You can quickly set `nvram boot-args="-no_compat_check"` (may be the only setting you need, after [installation](...), to run Big Sur on an only slightly incompatible mac).

- - You can quickly set/clear `StartupMute` (which doesn't require Recovery mode to set normally; I just found it useful to add it here).

 ### Advanced
 
-To use as an OpenCore tool, copy `EFI\BOOT\BootHelper.efi` into the `EFI\OC\Tools` of an existing Open Core boot disk, and then configure this as a tool in the `Tools` section of `EFI\OC\config.plist` (following the pattern of any existing tools in there).

 `BootHelper.efi` can also be run from OpenCore Open Shell or any other UEFI Shell, if you already have one configured.
