Note that when you install gdb with Homebrew, the following is shown: => Caveats I ended up doing brew reinstall gdb, deleting all the certificates I had created, rebooting and then very carefully following the procedure again. I can't really believe how often disabling SIP is suggested as a solution to this problem - if you get desperate I'd sooner advise running sudo gdb (have backups!) than disabling SIP.įor me, the problem was that I repeatedly messed up one or more steps in the procedure. Yes, code signing should work is a substantially better alternative to disabling SIP.

So I went through the instructions (except for the ones for Snow Leopard), and it still doesn't work! Anyone knows how I can make it work? So I googled a bit about codesigning, and found this. (please check gdb is codesigned - see taskgated(8)) Unable to find Mach task port for process-id 42492: (os/kern) failure (0x5).

So I installed GDB (The GNU Debugger) for following among a book I am currently reading ('Hacking: The Art of Exploitation'), which only explains how to use GDB, so I can't use LLDB. First I should note that I'm using macOS Sierra (version 10.12 beta 16A238m), but I don't think it's that different than El Capitan in this certain situation (but I guess you know more than I do about that, or I wouldn't be here right now asking this question).
