Fast forward to 2nd Steve Jobs era and Macs used the same hardware PCs used, for the most part. Only one item was MAC ONLY… that Power PC processor that Microsoft uses in their Xbox 360; Its a triple core PowerPC based chips made by IBM, but Motorola made them for Apple in the early 2000’s, but Jobs and others at Apple saw the SLOW, Turtle like progress Motorola was making with their Power PC chip, and looked at Intel map of where it was going, and it was a no brainer.
