First of all let me tell you that I am an apologist of free software, but when I change from Windows to Mac OS X I had some difficulty finding the right software, took me almost half a year to find good freeware replacements to all my favorite application, but I finally got it

So you don’t have the same problem I had, I will share with you the list of cool software that I found. I also found a good site to download all the software. If you got any suggestions or if you know a better application just let me know.
