Apple’s airtight secrecy has allowed it to do some wonderful things. But what happens when it’s difficult to tell the path of future operating systems? That’s the situation I’m trying to tackle with Mac OS X Leopard and now the upcoming Mac OS X “Snow Leopard.” The good news is, Apple says they’re focused on improving the "quality" of the OS. The bad news is, it’s not clear what the plan is for the existing 10.5 OS — or what it will take for OS changes to sync up with what we need as musicians and audio producers.
