The MacBook is coming back — or at least, that's what the rumors claim. Next week, Apple is expected to announce a colorful, low-cost, non-Air, non-Pro MacBook powered by one of its mobile processors. By avoiding its pricier M-series chips, Apple may reportedly be able to reach a low $699 or $799 price for the MacBook. The $999 MacBook Air is the cheapest laptop on the company's website right now, but Apple also sold the older M1 MacBook Air at Walmart for $700 in 2024, which later went down to $650 last year.
