On a sheet of Mac keyboard shortcuts for booting, one of them says, "hold down shift while booting and the computer will not load login items or extensions".
Am I wrong, or are Mac OS "extensions" something that were phased out a long time ago? (In other words, with OS X Lion, the shift key simply cancels loading the login items, period?)
Note that, of course, I know that "extensions" has meaning in other apps -- Firefox, Safari, Thunderbird, etc. But please confirm my Mac OS X suspicion as I describe it above.
(Yep, I know this is related to my other question. Getting this answer clear will allow me to resolve both questions clearly and designate their correct answers.)
