Mac mini flashes pictures of keyboard and mouse at start up

Hi, T1no33, that’s an easy one… plug in a usb wired keyboard + mouse or have a charged up bluetooth keyboard and mouse close at hand.. blueooth connectivity can be iffy/troublesome at startup, kinda hit-n-miss… so a usb wired keyboard+ mouse is recommended. Pretty much any kind/any one /and brand will work.. could be pc or mac doesn’t really matter…
