Apple has delisted the 2015 MacBook Pro which it was selling alongside the newer Thunderbolt 3-only MacBook Pro models.

Needless to say that Apple made a ‘courageous’ move ditching USB-A ports altogether on its notebook lineup when it announced the new MacBook Pro with Touch Bar and Thunderbolt 3. But of course, Apple wasn’t too harsh right out of the gate as it was selling the 2015 MacBook Pro alongside its pro lineup of notebooks. Basically, what that meant was, if you wanted something that had a complete array of ports, including USB 3, an SD card slot and more, then the 2015 model was the way to go. Obviously the 2015 model was slightly slower compared to the newer models, but we knew that the aging machine wasn’t going to stick around for a long time.
