Hi there, I just realize that my osX86 version is not enabling the Execute disable bit functionality of the CPU. In particular, I could run code in the stack without any issue whatsoever. I'm running Pascal 10.4.10 upgrade over an uphuc's 10.4.9 v.1.4i r2. Is NX just stripped out in these hacked versions or is it just my installation? Is there anyway I can activate it?
