Mac mini now has fourth-generation Intel Core processors, increased graphics performance, and ultrafast 802.11ac wireless networking. It also features two Thunderbolt 2 ports, great built-in apps, and OS X Yosemite. And it's still the world's most power-efficient desktop.
The Mac mini is an attractive, affordable and efficient OS X machine. The Intel Core i5 processor provides more than enough power for Web surfing and entertainment. The Yosemite OS is a powerful and reliable operating system, In all this entry level Mac works well for my needs.
