Do you mean an APC? They I know have advertised in Mac catalogs long before Apple's latest growth spurt.
One word of caution about UPSes, they are no substitute for unplugging the computer during a lightning storm. Nothing can resist lightning completely, although it can be redirected most of the time by a lightning rod. Still even with a lightning rod, there is a chance of lightning deciding to jump the circuit, and fry the UPS and even part of the computer if it is plugged in to municipal power. While UPSes will often warranty against damage due to lightning, they can't substitute having an off site backup, or at least a detached backup. Only backup your systems in fair weather.
