I rcently had to reinstall Leopard on my iMac, due to an Update from Tiger and two migrations something was badly broken. So a clean start.
This is the list of of Software I installed, it will be Updated as needed:
Firefox with Firebug: Simply the best Browser for web development.
Skype: for everything chat.
Cyberduck: FTP.
Jumpcut: a great clipboard manager with history function, lives in your menubar.
OpenOffice.org: In my opinion every bit better than Microsofts waste of time and Money.
Aptana Studio: Integrated Development Environment (IDE) for Web Development, includes Support for PHP, JS, Ruby on Rails, Adobe Air. A must have.
Tweetie: Twitter client, also available for iPhone.
NetNewsWire: THE newsreader for Mac. Period.
Transmission: simple BitTorrent client.
Handbrake: Video converter, converts DVDs and other types of video to iTunes-compatible format.
MacTeX: LaTeX disptribution for Mac. I use it with the songs package for typesetting guitar songbooks.
Smultron: All purpose text editor, features syntax highlighting and regex searches.
VLC: Media Player, If VLC doesn’t play it, nothing does.
Perian: Codec pack, enables Quicktime to play all popular video formats.
IPSecuritas: VPN client. If you use Windows you gotta pay for that kind of functionality.
Growl: unintrusive notification system.
Plex: Media Center
