It was already rumored that Apple was planning to unveil a new MacBook Air in March, and now we have confirmation straight from the source. Apple’s CEO, Tim Cook, took to social media to share a teaser video, accompanied by the caption “this week.”

The video features music playing in the background as the text “there’s something in the air” scrolls across the screen. The video then cuts to a distinctive ultra-thin swoosh, which is likely a hint at the upcoming M4 MacBook Air. Although we don’t know the exact date of the announcement, it’s expected to happen sometime this week, so stay tuned.

The M4 MacBook Air is anticipated to be available in two sizes: 13-inch and 15-inch, according to a report by Bloomberg’s Mark Gurman. Apple introduced the M3 MacBook Air last March, so a yearly update is overdue. The M4 chip, on the other hand, was recently introduced to Mac computers a few months ago, initially appearing in the iPad Pro before making its way to the iMac, Mac mini, and MacBook Pro in October.

While the phrase “there’s something in the air” could potentially refer to a refresh of the iPad Air, it’s unlikely. A new design for the iPad Air was released in May, so an update is not expected soon. However, the base iPad is due for an update, which might be a possibility.
