Anyone get mach_inject working on snow leopard?

Question

Project is now on github and here is the link to my issue

I successfully compiled the whole thing and able to run rejector and rejectee separately. But the injector will crash the injectee when injecting code to the target process.

mach_inject_test_injectee.app 's standard output:
mach error on bundle load (os/kern) successful
mach error on bundle load (os/kern) successful
mach error on bundle load (os/kern) successful
mach error on bundle load (os/kern) successful

hi

It seems from the output the injector is not notified from the injectee, any ideas? thanks.

This thread should help you out, it looks like a patched version exists in the simbl tree. The caveat being you can only inject into an app of similar bit depth (32 or 64).
