Apple Offers Developers a Closer Look at the New Mac Pro
After the keynote, WWDC attendees were able to get a closer look at the Mac Pro and Engadget posted a number of photos as well of a video of the new Mac Pro.
The new Mac Pro is a fraction of the size of Apple’s last Mac Pro, which was originally released in mid–2010 with a small update in 2012. Though it is significantly smaller, the Mac Pro will include features like a full-sized HDMI connector, four USB sockets, six Thunderbolt 2 ports and two gigabit Ethernet ports.
Apple has not given an exact release date for the Mac Pro, but it is expected to debut later this year and it will be the only current Apple product assembled solely in the United States. MacRumors has additional photos of the Mac Pro provided by a developer.
