A desktop experience that draws you in and keeps you there. This is the idea behind today’s iMac. And now that idea is more powerful than ever. The new iMac is packed with all-new processors, the latest graphics technologies, innovative storage, and higher-bandwidth connectivity. And it all comes to life on the brightest and most colorful Retina display iMac has ever seen. So you get an even more immersive experience — and a scintillating new way to take it all in.

Retina at its most brilliant.

The Retina display shines even more vividly on the new iMac. With one billion colors and 500 nits of brightness, graphics leap off the screen in a whole new light. And the pixel density is so high that you won’t detect a single one. Text is so clear and sharp, your email and documents will look smarter than ever. It’s simply the best Mac Retina display yet.

IPS technology and LED backlighting

The gorgeous iMac display looks great from any seat in the house. A technology called in-plane switching (IPS) gives you a bright picture with excellent color from nearly any angle. And LED backlighting offers instant-on, uniform brightness with no waiting. So you’re always ready to share that vacation slideshow with the family.

Graphics that render you speechless.

iMac features powerful new Radeon Pro 500 series graphics that make a spectacle of everything you see.

Faster 802.11ac Wi-Fi

iMac now supports ultrafast 802.11ac Wi-Fi. When it’s connected to an 802.11ac base station — including the new AirPort Extreme and AirPort Time Capsule — wireless performance is up to 3x faster than with the previous generation of iMac. And your Wi-Fi range improves as well.

Thunderbolt 3

Two Thunderbolt 3 (USB-C) ports come standard on all iMac models, each delivering up to 40Gb/s data transfer for external drives and cameras and twice the bandwidth for video and display connectivity.

USB 3

Four USB 3 ports give you plenty of options for connecting peripherals, including your printer, iPhone, thumb drive, and more.

Bluetooth

And with ultrafast three-stream Wi‑Fi and Bluetooth 4.2 wireless technology, you’re instantly connected to all your favorite content.

FaceTime HD camera for high-resolution video calls

Get everyone in the picture with crisp, widescreen HD video. The built-in 720p FaceTime HD camera lets you make video calls that are so clear, it seems like everyone’s in the same room. Make FaceTime calls from your iMac to any FaceTime-enabled Mac, iPhone, iPad, or iPod touch.
