I recently ran into the dreaded “waiting for scanner” Mac Preview nonsense, where it essentially got stuck trying to scan a document.
The fix was rather trivial once someone figured out what process to kill:
$ ps -A|grep Image
601 ... /System/Library/Image Capture/Support/icdd 705 ... /System/Library/Image Capture/Support/Image Capture Extension.app/Contents/MacOS/Image Capture Extension ... other stuff
$ kill 705
The hilarious part, though, was to read the original post and compare the uselessness of the “human bot” who completely failed to understand what was going on (despite the fact that, in theory, this person should have been somewhat “trained” to within this very area of expertise) and instead just spouted out inane pre-digested blurbs.
It is obvious that the Tech Support person would not pass the Turing test: if I’ve ever seen a job ripe for being handed over to our AI overlords, this is definitely one!
