Of course Macs use IRQs as well, they just work harder to hide such details from you. IRQs are a way for hardware to tell the your app/driver/whatever that "Hey, you wanted to know when something happened to me. Well, it happened, do something!" Otherwise, drivers etc. would have to keep polling the hardware constantly, causing an extreme loss of performance and it could mean missing events entirely.
