The other day I did data migration from Mac to Mac for the first time in my life! In the past, I was using Windows etc, so it was all that I did not understand what I needed, the time required.

I examined the way of migration beforehand, but with information! As the knowledge that the predecessors such as Apple's official website and gadget blog left behind comes out on the net at random, I am weak

Which one to watch! ! ! State w w

Conversely, it was difficult because many sites covered various information.

I"Migrate from Mac (USB - C) to Mac (USB - C) using an external hard disk"I will summarize only the method of data migration when it is done under the condition.

By the way USB - C is this type of thing.

By the way, I have both the source Mac and the destination MacMacBook Pro (13-inch, Late 2016, Four Thunderbolt 3 Ports)is.


What is necessary for data migration using Mac external HDD

Only these four are necessary for data migration.

② New Mac
External hard disk
USB-C port

External hard disk,Webledge's KakeWhen I asked Mr. "Transcend USB 3.0 / 2.0 2.5 inch HDD Portable Hard Disk"Is good! I taught it so I bought it immediately.

The USB - C port,Mr. Horiguchi of MonographStarting with "many bloggers recommended"Satechi Multi USB USB Hub Type-C "Purchased.

I got lost because there are various USB - C ports and external HDD, but since they taught gadgets like two people, there was no mistake!

Data migration work and time required using external HDD

The time it took to complete the entire work (backing up old Mac data to old Mac data)3 hoursAbout The digest of the work content and the time required for each was like this.

① Back up old Mac data to external HDD (30 minutes)
② Transfer backup of external HDD to new Mac (30 minutes)
③ Initialize old Mac data (1 to 2 hours)

There is not really time anymore! As soon as people do not do it, Youtuber's Kaz's video will be a good reference so please take a look at these two.




I want to see it more carefully and politely! It is nice to have people read until the end.

By the way, most people initialize the old Mac after the transition. However, I forgot to take a picture screenshot! Lol

So please take a look at these two articles.
