Migrating from Time Machine or Carbon Copy Cloner

I'm going to set up a new Mac. I have backups on Time Machine and Carbon Copy Cloner drives. Which would be better to use for migration? Not so much interested in speed a in reliability of getting all the data onto the new system.


Thanks very much.

I just migrated from a High Sierra iMac to a Sequoia mini a few days ago. I had your backup choices too. I went with using Time Machine and doing so as part of Setup. Do it during setup and it will create your old user folder. Do it using Migration Assistant later and it will create a new user.


Of course there was no point in my cloning a HS backup to a M4 mini and I just figured let Apple handle all the decision making.


In my case the "complexity" was that I was going from a larger internal drive to a smaller one, but that's beyond what you need as part of a reply. ;-)

If you want to use Migration Assistant during the initial setup of the new Mac you'll have to use the Time Machine backup. The CCC backup won't work with MA.


Is that something new..?


I'm asking, because less than a year ago I moved the wife to a new Mac using a CCC clone of her old Mac.


Steps for Migration:

  1. Boot your new Mac: Start up your new Mac and follow the initial setup prompts until you reach the migration screen. 
  2. Choose Migration Assistant: Select the option to migrate data from a backup, then choose your CCC backup as the source. 
  3. Select Data to Migrate: Migration Assistant will present the contents of your backup, allowing you to choose what to transfer, including applications, user accounts, and settings. 
  4. Follow On-Screen Instructions: Complete the migration process as guided by Migration Assistant. 
  5. Boot and Log In: After migration, reboot your new Mac and log in to your user accounts.

Seems either way...


a Clone is a clone —maybe it separates the user data from the macOS....(?) The macOS will not go backwards, only the same or forward.


You do not say what old machine/Intel/M-series/ macOS...to your new machine? I tend to move everything on the initial boot up with TM.


The most trouble free way to move to a new machine, is using the Setup Assistant on the initial boot of a brand new machine— you have one shot here. Set up your MacBook Pro - Apple Support


The second best way is use the Migration Assistant.

My family members use CCC for backups and Migration Assistant to restore that to a new Mac. Works great. Personally I manually restore CCC backups via the Finder when doing a clean install.


Whenever I get a chance, I nag them to update their MacBook backup to the external SSD I bought them as a Xmas present.


I guess both Time Machine and CCC backups would work just the same.
