The new Mac Mini with the M4 chip is a ridiculously powerful computer packed into one incredibly compact package. This very small design forced Apple to place the Mac Mini's power button on the bottom and this caused people to criticize Apple. Because of that, now this accessory to easily press the power button has been removed.
It is named as iFixTheButton and is a plastic accessory produced through 3D printing. It's designed like a seesaw with one end with a small round surface to slide under the Mac Mini, then at the other end is a slightly larger round surface to easily press the power button without having to lift the Mac Mini.
This power button accessory design is provided for free via the Github site. Because the creators of these accessories provide open access, believe me there will be accessory manufacturers from China producing similar products in bulk production. In Malaysia, the Mac Mini is sold at a price starting at RM2,499.
