Software just works
In the world of iMac, nothing is complicated — even when the internal architecture advances so dramatically. So when it comes to running software on your Intel-based iMac, prepare for the expected: it just works. Applications with the Universal symbol run on either PowerPC- or Intel-based iMac computers. Most existing applications will run on your Intel-based iMac, too. Simply launch them as always. Thanks to the Rosetta technology in Mac OS X, they look and feel just like they did before.
