Jamaica (who has a sister named Jessamyn and who grew up one town over from where I grew up) came in with two ancient Macbooks. "All I get are family hand me downs!" She couldn't log in to one, had tried every password. "Did you try... no password?" She did not know that was a thing. We tried it and presto! She had to go because she had some loose sheep at home, I told her to update from Mac OS Sierra when she got the ewe back.
