For a week, we have been seeing reports that the newly released MacBook Pros run hot, which all kicked off after this video by Dave Lee. They run so hot, in fact, that the very fancy 8th Gen Intel Core processors inside them were throttled down to below their base speed. Apple has acknowledged that thermal throttling is a real issue caused by a software bug, and it’s issuing a software update today that is designed to address it.

The company also apologized, writing, “We apologize to any customer who has experienced less than optimal performance on their new systems.”
