The expected Apple M1X Mac Mini has apparently been delayed. There were rumors that the revitalized compact desktop PC would be launched alongside the M1X MacBook Pro 14 and MacBook Pro 16 at an event in October. However, a leaker has now asserted that there will likely be a much longer wait for the M1X Mac Mini.

That proposed Mac mini design is clearly not accurate or functional. The claimed "schematic" is just an early rough concept, with no final input on design or ports or much else. Those purported Thunderbolt ports are proposed air holes instead. It doesn't matter since that so-called leak just exposed they don't know what a schematic is.
