Apple is expected to launch a smaller Mac Pro and a redesigned 24-inch iMac with Apple Silicon processors in 2021, and Jon Prosser has shared his look.
Rumors suggest that the Mac Pro would be upgraded so that the M-series processor would be about “half the size” of the current Mac Pro. The iMac was expected to receive some sort of end-to-end screen redesign similar to the iPad Pro.
Well-known leaker Jon Prosser shared representations of the products based on descriptions and images that were leaked to him. The first is the small Mac Pro described as a concept similar to the G4 Cube with a computing unit at the bottom and heatsink at the top.

The second leak corresponds to the redesign of the iMac. The images show an end-to-end screen and colors similar to the iPad Air. Prosser notes that renderings have the current I / O on the back, but only for rendered ones. You haven’t seen the back of the redesigned iMacs.

Prosser described the leaked devices as “prototypes,” so there is no indication of when they could be released. With a March event still in question, the likely launch will be in late 2021.
