Developers Tools

These are required to get gcc and the like. They are available for download from the Apple Developer Connection, http://www.apple.com/developer - one needs a free registration to obtain access. Or see MikePatterson.

Network Applications

FTP clients: Fugu is popular.

Web browsers: as well as Safari, versions of Mozilla and Firefox are available. Also, there is a port of Mozilla to the OS X "look and feel" called Camino. These can all be downloaded from http://www.mozilla.org. Older Mac users may remember Omniweb and Microsoft's Internet Explorer.

Text Layout

fink has many tools available; see OpenSourceApplications for a bit of help here. Texshop is another popular application; you can get it from http://www.uoregon.edu/~koch/texshop/texshop.html. Installing Texshop can be a bit of a pain. It is highly recommended that you follow the procedure with texlive, as documented on the main texshop page. Avoid using latex from fink if possible, I've seen this to cause problems. (Prabhakar Ragde told me about this). Or just get http://www.tug.org/mactex/ - MacTex. It installs a bunch of latex stuff, including TeXShop.

Gadgets

Here are some things I've found useful:

Desktop Manager: Allows you to have multiple desktops. Works nicely.

Equation Service: This little program is great for LaTeX users that want to render equations for presentations, web, etc.

SSH Agent: This saves you from having to enter your password when communicating with other computers via SSH. (Not required with 10.5 Leopard.)
