Wow you guys don’t get the manufacture part. These are built not by Apple. Not by Tim. Or anyone else at HQ. They send very detailed plans, CADS and such to a factory in China. Someone there screwed up. They could have put a decimal point in wrong or a 8 instead of a 9 in their machines that mill the chassis or mount. Or the line they are made on wasn’t exactly 100% true to specs. The slab of aluminum could have shifted ever so slightly. That’s in no way Apples fault. They can not inspect everything and every step.
