The instructions found at Setting Up Kernel Debugging (http://fieldofcows.com/index.php?title=Setting_up_Kernel_Debugging_on_OS_X) are what I used to get to this point. On the machine running the kext I want to debug, I do see the message "Connected to remote debugger". On the machine I am running gdb on, I do see: The problem is that 'showallkmods' returns an empty list and none of the other similar commands appear to be working: (gdb) showalltasks task vm_map ipc_space #acts pid process io_policy wq_state command Invalid type combination in equality test. Now, I suppose one problem might be that when I check to see what version of the OS I am running via the System Profiler, it says Mac OS X 10.6.8 (10K549). I have tried hunting for a kernel debug kit for 10K549, but haven't been able to locate one. However, what is also strange is that I haven't been able to relocate the kernel debug kit for 10k540 either...which had me thinking that it may have been pulled due to some kind of issue. I am not sure what other details one might need to diagnose what has gone wrong, but if there are any, let me know and I will do my best to provide them.
