The M4 Mac mini's power button has been moved to the bottom of the chassis.Apple's VP Greg Joswiak explains that the placement is due to the reduced size of the Mac mini and the belief that users seldom use the power button.This design choice may not sit well with some users who are accustomed to traditional desktop PCs.Despite the change, the placement of the power button should not significantly impact the overall experience of using the M4 Mac mini.
