I came across this great list of free software for the Mac the other day through another blog that I can not find again to reference to.
The software list is broken up into categories including Productivity Tools, Pictures, Educational and Specialist Software, Internet and Communication Tools, Music, Utilities and Movies.
There are some really good applications for the Mac listed there, and many of them are actually available for the PC and Linux as well. I downloaded a few last night, including Gantt Project, AbiWord and Google SketchUp Free, so that I could try them out.
I’ll try to write some reviews of those applications when I get a chance to try them out fully.
