That alone shows that whoever made that post has no experience with modern Macs. System One was indeed designed to run one program at a time, and even in OS 9 you still had to manually allocate memory to get the best performace with multiple apps.HeyMAC said:
But OS X changed that, giving the Mac pre-emptive multi-tasking. budugu may be right about Windows vs Unix and multitasking vs. multithreading (I wasn't aware Windows had true multi-threading either; watch the CPU allocations in your Task Manager sometime) but that guy wasn't talking about Unix vs Windows. He was clearly referring to OS 9 with that memory allocation comment.
