I recently bought a new iMac. The biggest headache is how to synchronize the files of the old mac to the new mac. This experience is worth writing about and sharing with you. There are two recommended methods for migrating Mac to new Mac.
Solution 1: Migration Assistant for Mac Disk Cloning
The first option is using Migration Assistant. It's a macOS built-in tool used to migrate data from one machine to another one. Like from a Mac, Time Machine backup, or even a Windows PC.
The software is free to use. You can easily migrate data from one Mac to a new one by following the wizard step by step.
📍 Notice:
1. Connect the two computers to the power supply (the migration time may be very long).
2. Both computers are guaranteed to be connected to the same network using Wi-Fi or Ethernet.
3. The migration assistant is to copy (back up) all the resources of the old mac to the new mac. Don't worry about the old mac losing files.
Steps to Move Data from Old Mac to New One
Step 1:
On new Mac: Open the Migration Assistant software located in the Applications folder's Utilities folder.
When asked how you want to transfer the information, select the transfer option "From Mac, Time Machine Backup, or Startup Disk." Then click the "Continue" button.
On old Mac: Open Migration Assistant. When asked how you want to transfer the information, select the transfer option "To Another Mac." Then click the "Continue" button.
Step 2:
On new Mac: When asked to choose a Mac, Time Machine backup, or another startup disk, click the appropriate icon.
Click the "Continue" button. You may see a security code.
On old Mac: Skip these two steps if you have an older Mac booted in target disk mode or if you are migrating from a Time Machine backup.
If you see a security code, make sure it's the same on your new Mac. Then click the "Continue" button.
Step 3:
On new Mac: Choose the backup from which to transfer information. Click the "Continue" button. Choose which information to transfer from the backup. Click the "Continue" button to start the transfer. The transfer may take several hours to complete if there is a lot of content.
The process will transfer everything you choose to the new Mac without affecting the existing data on the new Mac. However, if there are users or applications in the same name, something might be messed up. So check and be careful when transferring user accounts and applications.
