Apple's latest incarnation of OS X, Leopard, apparently has had a hard time making the grade when it comes to accessing the New York City Department of Education's WiFi network.
"Apple is scrambling to address the WiFi connectivity issue within its Leopard operating system. The fix appears set to be included in the bug fixes of the upcoming Mac OS X 10.5.3 release, as noted in the report Successive Mac OS X 10.5.3 builds continue."
Until the WiFi connectivity is fixed the orders remain on hold.
