Ars Technica:

Despite all of Apple’s foot stomping about Universal Binaries and convincing developers how easy it is to straddle both sides of the Mac CPU fence, the company felt the need to take the much-buzzed new “Artist Lessons” feature of GarageBand ’09 to the side with greener grass. From iLife ’09’s system requirements section at the Apple Store online: “GarageBand Learn to Play requires an Intel-based Mac with a dual-core processor or better.”

Apple’s site and the iLife ’09 software box both state this requirement in fine print, though this increase in system requirements appears to be the latest in a new trend for Apple. The dramatically rewritten iMovie ’08 was the first iLife app to eliminate the G4 PowerPC from its supported CPUs, raising its demands to an Intel processor, a Power Mac G5 dual 2.0 GHz, or an iMac G5 1.9 GHz.

They’re going to be real sad when Snow Leopard rolls into town.
