I found this old message: http://lists.apple.com/archives/cocoa-dev/2010/Mar/msg01042.html
in which stated: If you think this is going to help you avoid piracy, it's not. OS X has a flag (PT_DENY_ATTACH) that the kernel checks for when a debugger asks to attach to a process. If that flag is set, the kernel refuses to allow the debugger to attach. iTunes famously does this to prevent people from inspecting the operations of the DRM system. It's a trivial matter to patch the kernel to not respect this flag, I was just wondering if this is still true or true in general...that it is not possible to conceal an application from DTrace.
