Well, I'd posit that Apple _set_ standards instead of following them.

For example, Apple's use of a DB-25 for a SCSI port and the pinout
they chose has been copied widely throughout the industry.

More conventionally, the serial ports follow normal pinouts, even
though they're electrically RS-422 instead of RS-232C.

In 1984, there wasn't any kind of a standard in place yet for a
mouse interface.

And as someone else pointed out, Mac power cords fit just about
any computer device from the PC era forwards.
