So I just installed some new memory in my 2011 Mac Mini and I want to run memtest on it.  The memtest instructions recommend running it in single user mode.  You're supposed to be able to get into single user mode by holding Command+S during boot up.  However when I do this the Mini just boots normally.  I've tried multiple times and have not been able to get it to work.

 

Is single user mode somehow disabled in Lion and/or with this new hardware?

Mac mini, Mac OS X (10.7.3)
