The main Chinese MacBook factory has been working with a reduced workforce that has been locked inside the factory as a result of Covid. They are not happy about this. If you are considering buying a MacBook, do it now. Apple does not have a warehouse full of Macs. They operate on a "when needed" production cycle. Delivery for the 14" and 16" is sometime in July.
