Rumors suggest a “finally” moment, with Apple on the verge of completing the redesign of the newest generation of the Mac mini, this time featuring an M4 chip. This could result in the smallest Mac ever.

The current Mac mini design dates back to 2010, when Apple was still using more power-hungry and larger Intel chips. The only change over the years has been the back portion to accommodate a variety of port offerings. When Apple transitioned to Apple Silicon chips, right after the Apple Silicon Dev Kit was made available, I expected a redesign and saw the Dev Kit as a transitional step, simply because the chip is smaller, more power-efficient, and requires much less cooling. To me, this was the right time to do so. However, they did not.

If you look inside an M1 Mac mini, thanks to this teardown guide from iFixit you can see that there is some empty space. Coupled with what Apple can do with the M4 iPad Pro, and the environmental pressure to be more efficient in resource consumption (power, materials, etc.), it is clear that the Mac mini must be rethought from the ground up. Will Apple go with an external PSU for this? I don’t expect this to be the case.

One more thing: I’ve been a satisfied user of the M1 Mac mini since 2020, but I’m increasingly considering an upgrade, either to the Mac Studio or a more powerful Mac mini. I’ll be sure to pay close attention to my options.
