Had to Installed some updates, and I had to restart for updates to be completed(a kernel update I think)
Hit the restart switch on the pop up, and it went to restart mode.
After the machines splash screen, there came a blue screen saying to:
’hit any key to enter MOK management’
I did that, and got a small menu with some options, one of them being ‘Continue Boot’ which I selected and Leap started.
Is ‘MOK’ part of the machine firmware code, or is it related to Grub?
I think it has something to do with secure boot, but not sure.
