MacTech Magazine has announced that its MacForge Mac open source project index now has over 45,000 projects. MacForge.net was created for not only the experienced open source user, but to introduce the Mac technical community to the wide array of projects available. With the huge availability of open source out there, it can be difficult to find projects most relevant to the Mac. MacForge indexes open source projects that either have already been built for/tested on the Mac, or are likely to run on the Mac, without major porting work. The site also features the ability to filter projects further, search, browse categories, and sort in a variety of different ways.
