> Apple uses the same tools you do.

No. A special directory can be created at the root of the file system called /AppleInternal. Then, if you work at Apple, you can put some special files there that do stuff. I've read somewhere that they are able to easily disable all of this privacy protection crap and other annoying stuff.

There's nothing really special about /AppleInternal, it's just a fairly normal directory that a couple of tools change in order to do things like offer more detailed diagnostics or the option to create a Radar. On a normal internal install there are some internal utilities, many of which are listed here: https://www.theiphonewiki.com/wiki/Category:Apple_Internal_A.... But their code is all Xcode projects and stuff, it's not like they're really using special tools for themselves except in certain cases. There are a couple of internal tools that possess entitlements to bypass security, but more often than not engineers just run with the security features disabled, which you can do yourself.
