Hi all,

I am using an Intel iMac and I have recently installed Big Sur. I am trying to boot in recovery mode in order to "allow user management of kernel extensions" but regardless of what combination of keys I press (Command+R, Option+Command+R, Shift+Option+Command+R) I always end in Internet recovery mode which doesn't provide the options I want.

Is there any other way to enable these extensions or is there any other way to boot in non-Internet-Recovery-Mode? For instance in this video:


at 01:07 it goes into macOS Recovery where the user can manage the kernel extensions manually.

Please help, thanks.

Hi! there's a little workaround that helped me before : try turning on the mac with "Option" key to access the startup manager. When you reach the "choose a startup disk" screen, press "Command + R" and see if it help.
If it still doesn't work, your internal mac recovery may be corrupted by something and to get it back you'll need to reinstall macOS and then try Recovery mode one more time.
You can find other tips in this article

Thank you for the answer but unfortunately "option" + reboot didn't help.

I tried to reboot in Internet recovery mode again and ran the following:

kmutil trigger-panic-medic --volume-root /Volumes/MacintoshHD

but the command "kmutil" is not being recognized in the bash shell 3.2. It seems that some kernel extensions are in the user's library and these don't get loaded automatically unless they are explicitly allowed to do so. Here's a screenshot of mine:

I've also entered the following command in a Terminal window:

sudo kmutil load -p /Library/Extensions/FirefaceAudioDriver.kext

and that didn't work either.☹️

Just to let know everyone that the problem has been solved. I just downloaded the Samsung Portable SSD for Big Sur installer which updated the kernel extensions for the SSD disk and it seems that for all other extensions as well.;)
