bp_set doesn't work in OS X EI Capitan??

[DarthL]

I am reading the book 'the-mac-hackers-handbook' and very interesting in pydbg64. I downloaded this code and tested my program, I find it will crash when calling the bp_set .I guess the reason is the memory of code is not writable and the function will replace the byte in the address with "0xcc", right? So,how to fix it ?

No idea, this is abandoned software. Fixing it should be a good exercise if you want to learn the internals of OS X.
