- PowerPC (Rosetta) emulation is no longer offered. That means if you have any PowerPC applications they won't be able to run in Mac OS X Lion. You can determine if you are still running PowerPC applications by going into Applications -> Utilities -> System Profiler -> Applications and viewing "By Kind". This will show you which applications you have that are running under PowerPC. Rosetta had already become an optional install in Snow Leopard, and it appears Apple will be removing support for it entirely in Lion.
- QuickTime Player finally re-incorporates some features from QuickTime Pro. New features cited include Copy/Paste, Insert Clip, Crop Video, Rotate Video, Resize, Trim, More Export options.
- TUAW points to a video walk through of Lion from Ian Bauters that gives an overview:
Note: Unfortunately, Apple has been pretty keen on going after these sort of things, so the video has been taken down from YouTube.
Other highlights from the growing discussion thread details many smaller updates and features that users have found in Mac OS X Lion. An abbreviated list includes:
- Preview is a powerhouse app, you can even sign your document just by holding a piece of paper up to the camera with your signature (it saves it for you!) (screenshot)
- There's animations for everything, slick simple transitions that remind you of the polish of the iphone. Stuff that makes it easier to understand what your OS is doing with visuals
- You can turn the lights back (open application indicator) on in the dock (screenshot)
- iChat supports Yahoo Messenger Video and Voice chat
- Address Book also with "classic" view
- Much More
