Light. Years aheadOur goal with MacBook was to do the impossible: engineer a full‑size experience into the thinnest, lightest Mac notebook yet. And not only is it compact — it’s more powerful than ever. The new MacBook delivers up to 20 percent faster performance with new seventh‑generation Intel Core m3 7Y32 , HD Graphics 615 and up to 50 percent faster SSD storage.We Squeezed the Most Into It. And Out Of It.Each component inside MacBook has been meticulously designed to get the most out of an incredibly thin and light enclosure. We chose powerful yet highly efficient processors, and optimized macOS to draw on the processor using as little power as possible. Because no fan is needed to cool the computer, it has more room for battery cells to support you on the go, all day long.
