Now it’s time to turn on the new MacBook. the other end of the Thunderbolt cable to the old MacBook’s Thunderbolt port.the Thunderbolt cable to the Thunderbolt 2 end of the adapter.the USB-C side of the Thunderbolt 2 to USB-C adapter to the new MacBook Pro.Then, before turning on the new MacBook for the first time, I connected: This is all you need to do on the old MacBook. If successful, you will see a screensaver-like screen with a Thunderbolt icon.

This can be done by turning off the MacBook, then turning it on again, while holding down the T key. The first step was to put my old MacBook into target disk mode. This was the fastest cable supported (USB 3.0 isn’t as quick as Thunderbold). It seems that Apple only sells the 2m ones now. I used a 0.5m cable I bought a few years ago. This will be the case for most people, unless you’re upgrading from the 2016 MacBooks equipped with USB-C – in which case you just need a USB-C to USB-C cable. This was required for my setup as the old MacBook didn’t have a USB-C connection.

This week, I bought myself a brand new 2017 15″ MacBook Pro, upgrading from an early 2013 15″ MacBook Pro (with Retina).
