Mac Os X Leopard 10.5.4
In the example above, John Appleseed is a macOS user account. If you transfer an account that has the same name as an account on your new Mac, you're asked to rename the old account or replace the one on your new Mac. If you rename, the old account appears as a separate user on your new Mac, with a separate home folder and login. If you replace, the old account overwrites the account on your new Mac, including everything in its home folder.
After Migration Assistant is done, log in to the migrated account on your new Mac to see its files. If you're not keeping your old Mac, learn what to do before you sell, give away, or trade in your old Mac.
Migration Assistant makes it super easy to move data from your old Mac to your new one, either directly or from a Time Machine backup. You can connect two Macs with Thunderbolt, FireWire, or Ethernet, or even just using the same Wi-Fi network if you don't have one of these cables. Migrating your old data to your new computer will make it possible for you to start working on your brand new Mac without missing a beat.
If you are new to Mac, you can also migrate your old PC data.
Before you start
- Update your software - If your old Mac is running OS X 10.6 (Snow Leopard) or earlier, you will need to update your software first.
- Name your old Mac - If you haven't done so already, make sure your old Mac has a name. Open System Preferences > Sharing > and enter a name in the Computer Name field.
- Connect your old and new computers to a power source - Both devices need to be plugged into a power source to ensure that you don't run out of juice in the middle of the migration process.
- Get your Thunderbolt, FireWire, or Ethernet cable ready - Direct connection is the fastest way to migrate your data from your old Mac to your new. If you don't have the required cable, you can use your local Wi-Fi network instead, but the process will be slower.
How to migrate your old Mac's data to your new Mac
Start with your old Mac
- Connect the Thunderbolt, FireWire, or Ethernet cable from your old Mac to your new Mac.
- If you are using local Wi-Fi, make sure both Macs are connected to the same Wi-Fi network.
