Apple is at it again. The Cupertino-based company has just announced that it will be making its own chips for the Mac lineup of computers from early 2020. This will replace processors from Intel which have been powering Mac computers since 2005, before which Apple used the IBM-made PowerPC chips in its Mac systems. Back then, IBM processors just werenot competitive enough when compared with the Intel chips. They also ran hotter and used a lot of power, something over which Intel chips had a definite advantage.
