I’m constantly amused by the blurbs Apple attaches to their software updates:
This software update will upgrade your version of GarageBand 1.0 to GarageBand 1.0.1. This update clarifies specific alert dialogs regarding system performance.
Right. A 19.9MB update addresses alert dialogs. What are they, full–screen TIFFs? And are there a thousand of them? It’s be nice to know what else the update fixes… it’s not as though you’re tight for room in that little text box. Just say “performance enhancements” and we’d probably believe any sized update.
