What software do you install on your Mac? Our school district just updated us to 10.5.3 and wiped away all my old toys so I'm reinstalling.
Here are some of the things I've already installed, but I'd love your ideas!
NicePlayer--When I double click on a .mov file, it automatically opens to full screen and begins playing. Very nice!
Perian--allows me to play the .flv files I capture from YouTube with the Download Helper Firefox extension. I could also convert them from .flv with Zamzar or media-convert.com, but I like being able to play them right out of the box.
CaptureMe--There's a built-in grabber tool that works just fine, but CaptureMe saves in jpg (vs. png), which is very valuable to me. There is also some video capturing capability, but I don't use that very much.
321 Timer--This is a widget I find useful in my classroom and when I do professional development. Handy!
There are others I use, too, of course, but I didn't want this post to be too long. I like Handbrake & ClipCreator, Array & Scratch (from MIT), Jing, FlickrUploader, and Skype. And others, but they don't rate as favorites!
