Upon connecting the external drive to the Mac, the system will ask you, Do you want to use (External Drive Name) to back up with Time Machine? Choose Use as Backup Disk, but before doing that, make sure to check the Encrypt Backup Disk option, recommended by Apple itself.

What if Time Machine forgets to ask you to set a backup disk after connecting external drive? Do not worry, from the system you can do it manually.

    • All the files stored on the Mac can be located in the Desktop folder and Documents folder in the Finder beneath the iCloud.
    • If you are thinking to add a second Mac desktop, to merge the files of the first Mac with the second Mac, it won’t happen automatically. You can open the Desktop and Documents folder stored in the iCloud and find the folder named the same as mentioned in another Mac.
