This week, Apple revealed macOS Monterey, an update to its desktop operating system that will roll out this fall. It comes with a whole host of new features that the company highlighted in its keynote presentation at its annual WWDC event. But if you're stuck on a Mac with an Intel chip, some of those improvements won't make it to your computer at all. Apple computers have been largely powered by Intel chips since 2006. Last November, the company announced that it would switch to its own ARM-based M1 chips. Now with macOS Monterey, Apple has started to leave Intel behind.

Nine years ago today, Apple launched the very first iPhone. But the foundation for its success had actually been laid a year earlier. Ten years ago, in the summer of 2006, Apple had just successfully transformed the Mac, completing a transition from using PowerPC chips to Intel chips and essentially transplanting the the "brains" of its entire line of personal computers. The transition, which was first announced at Apple's Worldwide Developers Conference in 2005, was a big deal. Apple was moving from IBM-built PowerPC processors in its Mac computers to x86 processors made by Intel.
