All about the M1
Previously, every Mac ran on an Intel-based processor, which means Apple didn't have control over everything -- in terms of processing power -- like it does with the iPhone and iPad. But Apple has now cut the cord with Intel. It recently came out with its own chip for Macs, and the first version is called M1.
What does this mean for you as the customer? Apple said M1 is a faster processor, optimizes battery life, and allows you to install iPhone or iPad apps. The switch to M1 also brought a super-quiet Active Cooling system to the Pro lineup and completely removed the fan from the Air.
