The first time you start up a new Apple computer it asks if you want to transfer data from another computer. If you select yes, it opens Migration assistant, and gives you the option to connect to another computer. There are various ways you can connect. Some are very slow! Some are fast.
The slowest is to use wifi. If you connect your computers using wifi it may take days (literally days) to transfer the data across.
A faster way is to connect the 2 computers using an ethernet cable. This is still fairly slow.
The fastest way is to use a thunderbolt USB-C cable to connect the 2 computers together.
I recently used Thunderbolt to connect my new MacBook Pro to my old Mac Mini and it reduced the transfer time from days to hours.
Ethernet can transfer at speeds up to 1Gbps.
Thunderbolt 3 can transfer at speeds up to 40Gbps. It’s 40 times faster!
This is what a Thunderbolt (USB-C) cable looks like:
You simply connect the thunderbolt port of one MacBook directly to the thunderbolt port of the second MacBook.
When I unboxed my new MacBook Pro I booted it up and followed the prompts to connect my old MacBook Air to transfer my old files across. For some reason it did not recognise my old MacBook Air. I used the USB-C cable that came with my new MacBook Pro to connect the two computers together. It didn’t work.
The next day I tried again, this time with a different cable, and it worked. The USB-C cable that is supplied with new MacBook Pro is NOT a thunderbolt cable. So you cannot use it to transfer data. Apple saved themselves some $$$ by throwing in a cheaper cable that you can only use to charge. Read on and I’ll explain the differences.
A not thunderbolt cable.
This is NOT a Thunderbolt cable. It’s very similar to a thunderbolt cable. Some of Apple’s cables USB-C cables are Thunderbolt and some are not. The cable looks the same shape, but the Thunderbolt cables made by apple have a thunderbolt symbol on one side. This cable will charge your computer, but not transfer data.
Have a look at these 2 items in the Apple Store:
These cables are both USB-C. (That refers to the shape of the connector on the end). But one is a ‘Charge Cable’ and one is a ‘Thunderbolt Cable’. If you look very closely you can see the Thunderbolt symbol on one side of the connector of the Thunderbolt cable.
The one on the left will charge your computer. That is all it will do. The one one the right will charge your computer and it will also allow you to connect to another computer, or a SSD drive, iPad or any other Thunderbolt device. Guess which one Apple included when you purchased your new MacBook Pro? The cheaper one. They will both charge your computer. But the cheaper one will not transfer data from your old MacBook to your new one.
I have no problem with Apple including the cheaper charge cable, but it would have bene nice to have a note about this, or option to upgrade at the time of purchase.

It gets even more confusing if you head down to JB HiFi and but another USB-C cable because it’s possible to get a USB-C data cable that has a slower charging rate!
When you buy a USB-C cable you can get ones that charge fast, charge slowly, transfer data fast, transfer data slowly, or don’t transfer data at all. Apple’s charging cable does not transfer data at all.
Back in December I wrote this article about how Apple no longer sell any displays. Since then Apple have started selling a nice LG display that works with MacBooks. This has been designed in conjunction with Apple so that you can control the display’s volume and brightness from the Apple computer. It essentially functions as an Apple display but with an LG badge. On their website Apple describe it as: “A perfect complement to your MacBook or MacBook Pro.” The monitor plugs into the USB-C port on the new MacBooks. But the new LG monitors that Apple are selling don’t plug directly into to older Macs. What Apple’s website doesn’t say is that they sell an adapter that will allow this monitor to work with some non USB-C Macs.
UPDATE January 2019: Please disregard this article. The USB-C to Thunderbolt Cable is not as functional as it sounds. Foe example it would not let me hook a thunderbolt display to the USB-C port on my new 2018 Mac Mini, despite it’s claims of being bi-directional. So if you are thinking of buying the thunderbolt to USC-C adapter go into an Apple store first and make sure it will do what you want it to do.
