MacHacha

Sometimes, you really need to download a file but it only comes in bits and pieces. Then you have to put it back together again just like Humpty Dumpty. Well, MacHacha helps you do that. MacHacha basically is the equivalent of HJSplit but for MacOSX. It can split files into chunks or recombine them and allow you to download to your heart’s content from those file share services.
It’s currently freeware and open source under request.
