iTunes has been one of the last first-party Apple software holdouts stuck at 32-bit over the past few years. Many wondered when Apple would rewrite iTunes to the point where it would be 64-bit like just about all of Apple's other OS X apps, and that day has arrived with the release of iTunes 11. A quick check of Activity Monitor confirms it--iTunes is now a 64-bit Mac app.
Yesterday, Apple announced the new features and availability of iLife '11. We were definitely excited about picking it up, even though we noticed that a lot of the features that Apple was showing off in iMovie and iPhoto seemed to be fairly incremental (we aren't big users of GarageBand, so we couldn't tell you if the new features there were awesome or not.) So we figured that one unannounced "feature" would likely be that the iLife suite had been converted to 64 bit. After all, Snow Leopard has had more than enough time to mature out in the wild, and it seems that developers left and right have jumped onto the 64 bit bandwagon. That's why we were sorely disappointed when we launched Activity Monitor and found that, unlike just about every other process and application we are running on the Mac Pro, the iLife apps are still labeled as "Intel" rather than "Intel 64 bit." I guess we will have to wait and see what happens with iLife '12 or '13 at this point.
