The Libhelper Project

Libhelper is a cross-platform, multi-architecture library for assisting with Mach-O, Image4’s, different compression formats used by Apple, etc. It was originally designed to aid my development of Img4Helper however I began to develop it further and here we are. There are no external dependencies, therefore it can be easily used on macOS, iOS and Linux.

Libhelper is opensource, so I welcome and actively encourage you to check out it’s Github page and contribute if you can! You can find the source code here.


The latest currently available version of Libhelper is 1.0.0 (libhelper-1000.921.14.5) available for macOS, iOS and Linux. You can find download links here.
