Enter Single User Mode

[FN-GM]

Hi,

 

I have a MacBook here and i am trying to get into Single User Mode. I am pressing Command + S but its seems to be ignoring this and not going into Single User Mode.

 

Does anyone have any thoughts please?

 

Thanks

Have you enabled a Firmware Password by any chance? If you have follow the steps outlined in this KB Article:

Hi

 

Have you tried Command+v? Simply to see if you can access single user mode at all. It's possible there's a problem with the top case/keyboard? Try the other Command key - the one to the right of the space bar. Just to be sure you are pressing the command key aren't you? This is the key with the half eaten apple logo on it. Some get confused and hold down the ctrl (control) key thinking they are holding down the command key.

 

If you're still having a problem try a PRAM Reset. Command+alt+p+r at reboot. This will reset the unit back to its defaults. You should hear the boot chime. Do this three times then release the keys. Let it boot normally and restart. Try single user again.

 

Alternatively connect a USB Keyboard and try that instead. Does not have to be a mac keyboard as any USB keyboard should work. Depending on the keyboard the Windows key usually doubles for the Command key.
