It's not quite that simple, of course, and there is finally new leadership at the company that is at least acknowledging the situation. It appears that Intuit simply chose to neglect a portion of its customer base. The light at the end of the tunnel was a 10-million watt Klieg light on a big, loud train. How did Intuit end up screwing over loyal Mac Quicken users so thoroughly? We can take swipes at Apple for prematurely ceasing support of the Rosetta technology that supported PowerPC apps, but Intuit, along with every other Mac developer, saw the end looming for old PPC apps. What's worse, if you upgrade to Lion, you won't be able to extricate your data from Quicken at all, as no other app can read its proprietary format. It's the most infamous of the applications that have been left behind by the latest version of the Mac operating system, which no longer runs apps written for the PowerPC architecture, as Quicken 2007 was.
And if you upgraded to OS X Lion, Quicken 2007 will no longer work on your Mac. There's Quicken 2007 for the Mac, but nothing serious after that. If you're on a Mac, though, you might think Intuit has abandoned you. If you have a grown-up financial life, with money in investment vehicles, Intuit has an up-to-date version of Quicken to help you keep track of it all-on Windows.
