MacUnace is a decompressor for Apple computers that offers you the opportunity to be able to work with ACE file, one of the most widespread file formats over the Internet. The program isn't so intuitive as other decompression software applications like StuffIt or The Unarchiver, because it doesn't have a graphical interface, and everything takes place from the command line.

The program is compatible with some graphical environments, like UnaceX, but it's possible that we'll encounter problems when it comes to decompressing some files. Obviously, it's a rather complex application, that isn't recommended for users that don't use the “Terminal” interface included in Mac OS X.
If you don't know how to decompress ACE files on a Mac and you're looking for a program that will help you do so, MacUnace may be the perfect solution, because despite being one of the most complex options available, it's also one of the most effective.
