Apple announced iMac updates today at its event in Brooklyn, New York. As expected, the updates improve the desktop’s performance with new processors while maintaining the design we’ve known iMacs to have for the past couple of years.

Apple says the new system was designed from the ground up around the M1 system on a chip (SoC), allowing for a much smaller motherboard and cooling system than that seen in the company’s earlier Intel-powered iMacs. The new iMac’s overall volume is down by 50 percent and comes in at only 11 mm thick, with a single sheet of glass across the entire front of the device.

The iMac comes with a 4.5K Retina 24-inch display with very small bezels, resulting in a device not much larger than earlier 21-inch iMacs. The new displays also include TruTone technology, which dynamically adjusts color temperature in response to changes in the surrounding ambient light.
