As meaningful as GarageBand's mobile life is to Apple, the tune-making app is still considered a valuable piece of real estate on the desktop. However, last year GarageBand for Mac lost MP3 exporting as a feature, something which unsettled some of its users. The good news: today's release brings that back, once again allowing you to export those music creations as MP3 files. Additionally, Apple's thrown in a few Drummers and drum packs from various genres, including songwriter, rock and R&B. Who knows, these kits might play a part in you becoming the next Pharrell. Maybe, just maybe.
