New applications bearing the Universal symbol will run natively on both Intel- and PowerPC-based Mac computers. What about the applications you already own? Enter Rosetta. You’ll never see it, you’ll never configure it, you’ll never have to think about it. It’s built into Mac OS X to ensure that most of your existing applications live a long and fruitful life.

Protect your investment

Here are all the instructions you’ll need: double-click the application icon. Behind the scenes, Rosetta dynamically translates most of your PowerPC-based applications to work with your Intel-based Mac. There’s no emulation. No second-class status. It looks and feels just like it did before. On a Mac, you’d expect nothing less.

The Universal truth

Most of the applications that come on your Intel-based Mac are Universal applications, designed for screaming performance with the Intel Core Duo. That includes Mac OS X, iLife, Safari and Mail. Most existing applications will continue to run, thanks to Rosetta. Pro applications from Apple — including Final Cut Pro, Motion, Soundtrack Pro, DVD Studio Pro, Aperture, Logic Pro, Logic Express and Final Cut Express — are not supported by Rosetta. For most applications, you can upgrade to the Universal version for minimal cost (see “Upgrades” to right). Third-party applications that require precision real-time playback may perform better with a Universal version. For the expected arrival dates of Universal versions of third-party applications, check with their manufacturers.
