Huh?

“Huh?” is a colloquial English phrase used in iOS and Mac OS, which reached its initial "heyday" with the release of System 7.5.

Uses of “Huh?”

 * Under Apple Guide in System 7.5, a "Huh?" button appeared as an option for some complex topics. When clicked by confused users, it would take the user to a new window containing even more relevant information.
 * The Apple website briefly featured (in a section separate from the main Apple.com page) a section titled "Huh?".
 * Starting in iOS 13 set to American English, if a user says, "Hey Siri" without following up with a question, Siri can respond with "Huh?", "Uh-huh", or "Mm-hmm?" instead of "Yes?".
 * WikiMac itself was attempting to revitalise the usage of "Huh?" by applying it to pages where the user may desire more related assistance.

Reactions to “Huh?”
"Huh?" was apparently designed to be "user-friendly" to casual English speakers; it would mimic a situation where the user would actually utter "Huh?" in response to a term he or she did not understand. However, some non-American users disfavoured the term, believing that it was impolite for use in an operating system. Some iOS users took to liking it and would become distressed when Siri would not respond in the casual manner.
