Mac downloads ~ Apple


Adium ~ Chat Client
Growl Notifications
SuperDuper or CarbonCopyCloner ~ Both make bootable copies of your HD
HandBrake ~ Video Converting
Burn ~ As it says A Burning App
Transmission ~ p2p client
Skitch ~ Screen capture and more
VLC ~ Video player that plays most codecs and does a lot more
Perian and Flip4Mac Makes watching certain codecs easier ... This is Essential IMHO
Audacity ~ Play with Music App
CandyBar ~ Mods all your icons, and dock
MainMenu or Oynx ~ Does the same as Disk utility only more thorough
Quicksilver ~ Works like Spotlight but way way better and does so much more
StuffitExpander ~ Opens Zip and rar files and more
Lil Snitch ~ Firewall type App that looks at your incoming and outgoing traffic
and last but certainly not least .....
AppTrap ~ Once installed it sits in System Preferences and deletes all associated files of anything that you put in the trash ...

Should keep you busy for a while lol
