That depends on the Mac in question, and Apple. While a Mac model may have received model updates for the last couple of years, it is not guaranteed to receive an update every year. As a rule of thumb, however, MacBooks are more likely to receive yearly updates, while they’re desktop counterparts, like those above, tend to remain on lengthier cycles before newer models arrive. Don’t let a Mac desktop being slightly older put you off either – they are still excellent machines, and going for something a little older could save you a lot of money.
