This is one reason why programs written for a Mac can not run on an IBM-type PC.
While I'm sure that this was true at the time the book was written, PowerPC-based Macs are a thing of the past now. Thus, this statement might be a tad misleading to some of the readers, especially seeing how they're expected to be absolute beginners in assembly/machine code related subjects. I suggest changing this to reference mobile phones, since they're probably the most widespread non-x86 devices nowadays, and readers will probably be familiar with them.
