spctl "command not found" on Recovery start (mac OS Big Sierra) I've just updated to macOS Big Sur.
The firewall I use, Little Snitch doesn't work with Big Sur natively, and you have to do some stuff (they explain the thing here https://obdev.at/support/littlesnitch/245913651253917):

Start up your computer from macOS Recovery: Restart your computer and hold Command-R during startup.
Open the Terminal application from the Utilities menu in the menu bar.
Enter the following command and press Return:
spctl kext-consent add MLZF7K7B5R

My mac starts on Internet Recovery Mode and everytime I run the command I get the result &quot;command not found&quot;
I tried to look for the command in the route /usr/sbin/ but neither found there.

Any idea of what can i do to run it?
Thanks in advance and regards :)
You seem to have booted into an older version of macOS Recovery (there's an item called &quot;Install OS X Yosemite.app&quot; visible in your screenshot). This is something that can happen with Internet Recovery, depending on the Mac model and OS version.
If you use the regular local Recovery (⌘ R), the spctl command should be available.
If you HAVE to use Internet Recovery, try ⌥ ⌘ R. This should load the latest version of macOS compatible with your Mac.
