Ten things I like about Tiger (10.4)
OS X 10.4 (Tiger) has been officially available since April 29th. I've been lucky enough, thanks to a developer seed, to have been testing various builds for a couple of months. In that time, there are a number of things I've grown to love about Tiger (and a number I dislike, though those will come in a future write-up). With over 200 new features, I thought I'd try to pick out the 10 that I've liked the best so far.
Note that these are observations about OS X 10.4 only. Sometime I'll write a longer story discussing OS X in general, both what I like and dislike. But for now, here are my ten favorite 10.4 features...
- Apple's much-improved Mail program. From the toolbar buttons (yes, I like the jellybean shape behind the buttons, too) to the subtly colored mailbox panel to Smart Folders to the speedy Spotlight searching, the new Mail's a winner.
- System Profiler. In previous OS X releases, this tool was good, but not great. Now it's great. Information on just about everything to do with your system is but a couple of mouse clicks away. From graphics cards to displays to FireWire to USB devices to memory to PCI cards to printers to networking gear; even programs, extensions, fonts, and logs are detailed here. Very well done, and very useful when you want to know something about your machine.
- The free Developer Tools. No, I didn't suddenly become a programmer overnight. But some of the pre-compiled sample
toystools they provide are amazing. To name just a few that are fun to play with (on machines with better video cards), check out Core Image Fun House, Quartz Composer, and Quartz Debug, which will let you enable Quartz 2D Extreme (a way to accelerate drawing of 2D windows by using a 3D graphics card). Also, even non-programmers can use Interface Builder to tweak some elements of certain applications. - Core Image and Core Video. It may be a while before we really see the benefits of these features in OS X, but it will be worth the wait. Giving programmers an easy way to utilize newer 3D graphics cards will eventually lead to some amazing applications. See previous entry for one example of what can be done (Core Image Fun House).
- H.264. This QuickTime 7 codec (also available in 10.3) does amazing things for video compression. Jeff Harrell's Shape of Days blog has a couple of demonstrations (1, 2) of H.264 encoding, and the results are pretty impressive. In a nutshell, H.264 gives much higher quality (and/or size) at similar or lower bit rates than does MPEG4.
