British TV broadcaster ITV is officially supporting Macs for web-based viewing, it has announced. The network lets users watch a number of programs online, such as Coronation Street, Britain's Got Talent and Pushing Daisies; until recently however users were forced to use Windows, and ideally Internet Explorer. The site now runs on Firefox 1.5 and 2, as well as Safari; the key difference is that these require Microsoft's Silverlight plug-in, which operates similarly to Flash. Mac owners must be running Mac OS X 10.4.8 or later.
