You Find Yourself with a Lot More Accessories
Maybe at first, all you really had was a mouse and a USB drive. But now, things have gotten complicated. You have at least one external hard drive, and probably more. You find that you’re always hooking up other devices to your Mac to charge. You have a job or hobby that requires specialized accessories that you’re also connecting all the time. And you finally realize that the Air just doesn’t have enough ports anymore.
In this case, you are well-advised to upgrade to the MacBook Pro, which can increase the two Thunderbolt 3 ports to four total Thunderbolt 3 ports, giving you all the ports you need for exchanging data and powering up devices. Make sure the MacBook Pro that you choose features four ports, as some lower-end models only house two.
