This more for me than anybody else so I can go back and find these if I ever need them; I’d email them to myself but I never think to look there anyway.

First up is “The Best Unknown Mac Apps” Part 1 and Part 2. There’s also a much bigger list at creationrobot.com. Now in case those ever disappear I’m also going to link to the apps that I especially found interesting. [in no particular order]

Flip4Mac
This is probably going to be the absolutely most useful link on this list, since Microsoft is no longer working on windows media player for Mac, you’ll need this plugin to watch wmv in quicktime.

Applejack
Somewhat useful; hold down command and s to start in single user mode and then type applejack (or applejack auto or applejack auto restart to have it run through the whole list and then restart when it’s done if you want). Just some disk utilities and basic house cleaning. If you’ve got a wireless keyboard/mouse know that they won’t work. One the links later on looks like a GUI version that can do the same thing.

Soundstream
Screensaver that uses the mic to respond to ambient noise.

OnyX
I believe it has some of the same functionality of Applejack plus some more customization … seems like it’s an osX version of TweakUI.

Dashboard KickStart
This is one I’m really curious about because I have so many little fun but useless widgets on my dashboard that when I actually remember to use the dash, it takes forever and and a day to load … making the dash useless, and reinforcing why I forget to bother with it. If this doesn’t drag down load time to much, and it prefetches all the dashboard stuff then it’ll be very useful.

Barquee
Display and control itunes on the menu bar. Also of note check out Quartz Desktop while you’re there, I haven’t played with it but it appears that it’ll allow you to play .qtz files on your desktop … qtz files being animations/screensavers, which might be nice if you’re a big RSS fan, stick the rss screensaver directly on your desktop.

ViewIt
Acdsee for Mac; not sure about this one …. put it in just in case but may bail on it. Still weird that osX doesn’t have built in thumbnail views of pictures in folders. Using iPhoto is kind of pain in the ass just to browse through some pics in a folder.

CronniX
Haha, a gui for cron.

Keep in mind these are just fun little addons, osX/iLife/iWork … quit with the ‘i’ crap already … comes with just about everything you would ever want or need. The exceptions being stuffit expander (make sure you download expander from apple’s website, the stuffit website tries to get you to buy the full blown product … doubt you’ll ever need to actually create a .sit, but you’ll need to expand plenty of them.) and if you have a video ipod, podner, handbrake and mactheripper. Podner, which might be changing its name soon due to Apple being dicks about the “pod” in podner, but its absolutely brilliant for taking an existing video file (think divx) and converting it to ipod format (either mpeg4 or h.264). It does all the cropping, all the bitrate calculations, etc. Just drag the file, select the format and the quality and it goes on it’s way. Handbrake will rip your dvd to ipod video, little more complicated if you’re a quality fanatic like me. Mactheripper is a last ditch tool if handbrake can’t decode the dvd, use it to rip the dvd to your hard drive and then use handbrake on the rip.

I’m just starting on that top100 list so I may link out more apps later.
