It’s time to let go of the past, I suppose.

With the release of new MacBook Pro models, the MacBook Pro of 2015 has effectively been discontinued by Apple.

Why is this such a big deal? If you’ve been following Apple’s yearly refresh of its laptop line, you’d know that they’ve gradually let go of full-size USB ports and longer-travel keyboards in favor of slimmer designs.

This means the MacBook Pro that was released in 2015 is the last model to feature these legacy features.

In effect, if you’re going to buy a new MacBook Pro, you’ll have to embrace the dongle life, because your usual flash drives, external hard disks, and SD cards won’t fit into the USB-C-only ports of the newer models.

Of course, there are numerous accessories that simplify the need for dongles, but they’re still not as convenient as the slots that came built into MacBooks of old, including SD card readers, ports for USB-A, HDMI, and Thunderbolt, as well as the much-loved MagSafe power connector.

9to5Mac points out that Apple is still selling some 15-inch 2015 MacBooks in clearance sales for those who can’t let go just yet. Models from 2016 onward already have the updated design.

On the bright side, this year’s MacBooks are worth looking into. Not only do they come with the latest Intel Core processors and generous helpings of memory and storage, there are also improvements in the butterfly keyboard and signature Touch Bar.
