Restore a backup (.dmg) in QuickBooks Mac 2013 and above

QuickBooks for Mac 2013 and above uses a different process for backing up data, and requires a different process to restore backups.

When a data file is backed up in QuickBooks 2013 and above, it creates a disk image (.dmg) file.  Each disk image QuickBooks creates when it backs up your data includes a copy of your company file and your Attached Documents Library (if you use and back up attachments).

Detailed instructions
  1. Double click on the .dmg file by going to QuickBooks > Preferences > Backup.
    • Note: If the backup is not in that folder, you will need to navigate to the drive or folder where the backup was saved to, or open the Finder and search for files with the extension .dmg.
  2. A new window will open and a "Ghost" drive will be created on your Desktop. The window will display the backed up data file along with any Attached Documents QuickBooks would have backed up (if applicable).

  1. Drag the company file (with the .qb20XX extension) to the folder where you want to store the QuickBooks client file; also drag the Attached Documents Library folder (if applicable) to the same folder as the QuickBooks client file.
  2. Open your company file by double-clicking on it once it is in the new folder, or by clicking on File > Open in QuickBooks 20XX.
  3. You may Eject the "Ghost" drive created on your Desktop.


  If you need to restore your Attached Documents:

  1. Go to QuickBooks > Preferences > Attachments.
  2. Click the Attached Documents Library menu and choose Select Existing.

  1. Navigate to the Attached Documents Library folder you restored in Step 3 and choose it.
  2. Click Open.
  3. Close the Preferences window - your choice is saved automatically.


To restore qbmb or .mac.qbb non image backup files created in versions prior to QuickBooks for Mac 2013 or any QuickBooks for Windows versions:

  1. Locate the saved backup file on your computer (.qbmb from older versions, or .mac.qbb if from Windows).
  2. Double click the file and follow the onscreen directions which guide you through restoring a backup file to company file.
