According to Sony's UK website the PlayStation 3 console may potentially support Apple's Mac OS X Tiger.
"Sony is expected to offer optional hard drives for the PlayStation 3 with potential memory capacity of 80 or 120 GB. It remains to be decided whether the standard version of the PS3 will come complete with a hard drive," reads a company statement.
"The operating system has also yet to be clarified. The integrated Cell processor will be able to support a variety of operating systems (such as Linux or Apple's Tiger)."
