From MacRumors...<br><br>As we approach the release of Apple's Mac OS X 10.5 (Leopard), Appleinsider suggests that this may be the last major Mac OS revision that supports the PowerPC architecture.<br><br>Looking ahead, those people familiar with Apple development cycles speculate that Mac OS X 10.6 will exclude support for PowerPC-based Macs entirely, requiring that users have one of the company's Intel-based systems which first began making their way to market in early 2006.<br><br>Cited as speculation, Apple may not yet have made a decision on this matter. Apple has made no announcements about Mac OS X 10.6. Based on the most recent Mac OS development cycles, Mac OS X 10.6 would not likely ship until 2009.<br><br>
