How OS X Executes Applications

Posted by ryuzaki0 on from the learning-more-about-it dept.

MacHore writes "0xFE has an excellent tutorial on Mach-O, which is the file format used by OS X executable files and libraries. It goes into great detail about how Mach-O works, and explains what OS X actually does when it loads and runs an application. Subtopics include Universal Binaries, The Dynamic Linker, Using otool, and other goodies."

    Yes, because this information was a closely held secret before this meddlesome blogger came along. I bet Steve Jobs is really pissed and is taking out a contract on his life.
