Migration Assistant walks you through the data transfer process. Depending on how much data is being transferred, this can take quite awhile. Select the source and destination volumes on each Mac, the data you’d like to transfer, and have at it. Launch Migration Assistant on each Mac and then choose to transfer the data from the old Mac to the new one. This can be a network, FireWire, or Thunderbolt connection. I needn’t walk you through the complete process (because I’ve already done so here), but the gist is that you need to first establish a connection between the two computers. You’ll find it in /Applications/Utilities.
If you skip this step, all is not lost as you can invoke Migration Assistant from the new Mac once it’s up and running.
Transfer files from old mac to new mac install#
When you perform a clean install of Yosemite (or first set up a new Mac) Migration Assistant appears in the form of a query about whether you want to transfer data from another Mac, Time Machine backup or startup disk, or Windows PC. This will require your friend to put the old drive back where he found it (inside the old Mac), or connect the enclosure to the old Mac and boot from it. What I’d suggest in this case is to do things as Apple intended and use Migration Assistant. In cases where the OS is quite old and the computer quite new, there can be problems as new Macs often demand an operating system no older than the one that shipped with them. Those conditions include having an operating system compatible with the new Mac and a drive formatted in a compatible way. There are indeed conditions under which you can jerk a hard drive out of an old Mac, shove it into an enclosure, and boot another Mac from it. With the idea of saving your relationship, let me start by saying that your friend’s idea wasn’t entirely boneheaded. What’s the best and safest way for him to move that data over to his new Mac?
But now the new Mac doesn’t recognize the drive and is asking him if he wants to reformat it. He writes:Ī friend decided to remove the internal hard drive from an old Mac, put the drive into an external enclosure, and hook that up to his new Mac. Reader Walt Pinkston has an impatient friend who was a little too anxious to put old data on a new Mac.
