Apple announced that customers who placed recent backordered orders for the M4 Mac mini will receive a free upgrade to the newly introduced M6 or M5 Pro models. The company contacted affected customers, accelerated delivery dates, and maintained the original price. MacRumors reported that multiple users received the upgrade notification, and a Reddit post described a savings of about $300 compared with purchasing an M5 Pro at list price. Apple has not disclosed how many orders were upgraded. The Mac mini line has faced intermittent inventory shortages since its launch.
