MacBook

The MacBook is a brand of notebook computers manufactured by Apple Inc.. from early 2006 to late 2011, and relaunched in 2015. It replaced the iBook series and 12-inch PowerBook series of notebooks as a part of the Apple-Intel transition from PowerPC.

Features
The MacBook has a new keyboard and trackpad. Compared to previous models, the individual keys have a larger surface area. Apple replaced the scissor-like mechanism with a butterfly mechanism, making the keyboard thinner overall and, as Apple claims, individual keys more stable.
