I kinda like "venerable" better. It brought to mind legions of geezers executing malware willy-nilly... gazing at their monitors through magnifying glasses.
However, even if a user on a Mac launched a malicious program, it still could not access the core system files. 99.99% of Mac users operate their computers in a mode (Administrator or lower) that does not have sufficient access to modify system files (which requires Root access) while 99.9 percent of Windows users are natively running in PC Administrator mode which is the equivalent to Root.
