Certainly it is more invasive than what I had in mind, but I'm not really in a position to be picky if it works. I noticed in the documentation that he intends to one day add "mach_unoverride" support. So, what does this mean when my kext unloads? Sounds convoluted, but it still could be an option. ~ Josh On Dec 26, 2006, at 1:38 PM, Curtis Jones wrote: Albeit somewhat brute-force, Jonathan Rentzsch's mach_override can solve a lot of tough problems. With some adaption, you could use it to override the kernel's pset_add_task(processor_set_t pset, task_t task) or similar function with your own version. In this case you would simply get the needed information out of the task_t before calling the real pset_add_task. That is very interesting. I'm looking at it right now.

When you override, you are copying your custom function into the kernel's permanent memory. Your custom function will *not* be erased along with your kext (during unload). You would have to have a status bit in memory that indicates whether or not your kext is loaded, so that your override function would know whether or not it should perform the custom operations.
