The format needs to be translated before Macs can run these applications, and the translation is done using a process called Rosetta. PowerPC, though, is where the difficulties are found. Universal is similarly problem-free, as it includes both Intel and PowerPC support – the only problem being that this dual support increases the file size of these apps and eats up disk space. As you’d expect, the latter is fine, as all Macs these days run with Intel processors. Mac apps come in three different flavours: PowerPC, Universal and Intel. Is it possible to claw back control over these apps on your new operating system? What is the PowerPC format?

Yet this is a hard hit to take if you use Logic, Photoshop, Dreamweaver or any number of industry-standard applications in their current iterations.

The company’s made no secret of the fact that with this release, they’re ditching support for applications in Power PC format. So, enticed by smooth gestures, full-screen apps and an iOS-like Launchpad, you’ve made the move to Apple’s latest big cat, Lion.
