Apple just teased a $5,000 iMac Pro: 'The most powerful Mac we've ever made'

Apple hasn't given up on its most serious Mac customers.

At its annual conference for app developers on Monday, Apple teased the iMac Pro, its first professional-grade desktop since its flashy Mac Pro redesign in 2013.

Apple said this is the "most powerful Mac we've ever made," and CEO Tim Cook called it "badass" onstage.

The iMac Pro's starting configuration will be $4,999. The entire computer, including its keyboard and mouse, come in a sleek black finish. It'll go on sale in December.

Here are some of the key specs for the iMac Pro:

• A 5K display, with the processing to power two other 5K displays simultaneously.
• Up to 10-core Xeon processor.
• Up to 4TB of built-in SSD storage.
• Up to 126GB ECC memory.
• 10GB Ethernet connector.
