It’s an Apple rumour, so take with the usual mountain-sized grain of salt, but if the next release of Mac OS X (10.6 “Snow Leopard”) includes the CoreLocation framework previously seen on the iPhone/iPod touch platform, says rumour site AppleInsider, it will use Wi-Fi triangulation to determine a computer’s location. I wouldn’t, however, rule out the possibility that it could use a tethered GPS device as well, either natively or thanks to some clever third-party developer.
