One very cool feature of the
Apple System Profileris that one can see the
density (size) of all
memory modules that are installed.
For example: Slot 0 = 64Mb / Slot 1 = 128Mb / Slot 2 = 32Mb.
For a Mac OS engineer, this saves an enormous amount of time swapping out DIMMs and rebooting to ascertain the size of those modules (memory modules being rarely marked with their density)
The Apple System Profiler was created in 1995 and has no known easter eggs
