microcopy

 microcopy  is small bits of text, a word, phrase, maybe a sentence, typically in a UI, designed to very quickly and simply communicate something about the UI without going into a lengthy glaze-over explanation or use obtuse terminology. Due to its brevity, microcopy is often harder to write, and is considered a specific writing skill.

MacOS
When misbehaving apps die, MacOS provides a succinct, and reasonably understandable (and actionable) error message alert:

"DVD Player quit unexpected."

United Wifi
United Airlines has onboard wifi which sometimes encounters errors, in this case, the error message displayed provided a good general summary, followed with an apologetic description, and possible mitigations.

MacOS DVD Player
For what should be an amazingly simple task (playing DVDs), the Apple MacOS DVD Player app has some very bad microcopy in its error messages. e.g.



"DVD Player encountered a system error Error: -69889"
 * Why is it claiming a passive victim role? "DVD Player encountered"
 * Why is it blaming the mythical "system"? "system error"
 * Why is it providing a completely meaningless error number? -69889
 * perhaps only useful for a web search, which brings up an apple discussion thread:
 * https://discussions.apple.com/thread/1319259?start=0&tstart=0
 * but still, is that a reasonable user expectation for error messages? something to enter into a Google Search etc. to then sleuth for on the web?
