My least favorite thing on the Mac is when they have one of their infamous negative number “error codes” in the alert box, and I get my hopes up that at least it must represent a common thread of errors others have had that may be solved in a forum or subreddit somewhere, then when googling that you discover that all forms of failure from disk full to malware result in the exact same oddly-specific error code and that everyone is talking to each other about it and slowly realizing they have nothing in common but being cursed by Tim Cook.
