Keygens have always interested me and I found a tutorial for cracking apps on the mac os (educational only). I figured I'd try to follow the tut with the sample program given and Terminal is giving me the following error message: "Unable to locate task for process-id 6481: (os/kern) failure." In this case, I was using gdb's attach function to open up a running process. I'm assuming that there is some sort of permissions issue? Does anyone have any experience with this?
