iPatch is an easy-to-use patch maker for Mac OS X. It can compare the resources of two applications, and can produce a self-applying patches to update an older version of an application to a newer version.
MACONNECT it is not even able to do what it is supposed to do !!
It's corrupting the executable file half the time, and most of the time it changes more bytes than it is supposed to, making the patched executable instable.
