Getting to the core of the eligibility system on *OS.

I have been really interested in Apple internals recently, and I have been really into debugging/reverse engineering. I got the tools from Apple’s open source dyld project building (there were many missing components), and decided to play around with it a bit. I extracted the shared cache, and also got a map of all of the symbols and things like that.

Each executable, or ‘file’ inside the shared cache is called an image, and every image has “fix-ups” Apple applies to it before adding it to the shared cache (or after). Originally, the entire purpose of the DYLD shared cache was performance, and it probably partially still is, but in my personal opinion, there is an aspect of secrecy to bundling every library on the system into one file.

The fix-ups that are applied to the binaries are incredibly hard to work around. For example, some references into other parts of the shared cache are transformed into static addresses in memory, and since the share
