Apple has issued a statement confirming that the HomePod can leave white rings on wood surfaces that have an oil or was finish according to a report from macrumors. Apple told Wirecutter that "the marks can improve over several days after the speaker is removed from the wood surface." If not, Apple recommends "cleaning the surface with the manufacturer's suggested oiling method." Pocket-lint's review said the HomePod left a white ring on their table after only 2 minutes. So $349 for a spying device that also ruins your furniture. Sounds like an awesome purchase. I am now going to invent and sell a iCoaster for $49.99. Thank you to Susquehannock for the story, and my new found business venture. It's unclear at this point whether the issue is limited to treated wood, or if the problem could cause any sort of long-term damage to the HomePod's rubber base. For now, we would obviously recommend not placing your HomePod on a surface with an oil or wax finish if possible.
