2.3   Updating From a Previous Version

There are two ways to update to the latest version of DropDMG:

Automatic Updating

  1. Launch your old version of DropDMG.
  2. Normally, DropDMG will automatically check for updates and detect that a new version is available. If you have turned that feature off or don’t want to wait for the automatic check:
    1. Choose Software Update… from the DropDMG menu.
    2. Click the Check Now button.
  3. Click the Download & Install button and follow the on-screen instructions.
  4. You may be asked for an administrator password to ensure that incorrect file permissions on your Mac do not prevent the update from completing, leaving your Mac in an inconsistent state. The username and password for the automatic update are the ones for installers and logging into your Mac. They’re not related to DropDMG. If you don’t know your password, you can reset it or update DropDMG by following the “Manual Updating” instructions below.

Manual Updating

  1. Go to the DropDMG Web site and click the Download (Free Trial) button.

  2. Quit DropDMG.

  3. Replace the old DropDMG application file with the new one. That is, if DropDMG is installed in the Applications folder, drag the new DropDMG application icon into the Applications folder and click Replace when the Finder asks if you want to overwrite the old version.

    Note: If you get an error saying that the file is locked or you do not have sufficient privileges, drag the old DropDMG to the trash and empty it, and then drag the new one into the Applications folder.

  4. Launch DropDMG.

Mac App Store

If you purchased via the Mac App Store, you should update DropDMG using the App Store application.


DropDMG 3.6.6 is a paid upgrade for registered users of DropDMG 1.x and 2.x. Discounts and free updates are available depending on when you originally purchased DropDMG.
