Enterprise Whole Disk Encryption

Uninstall SecureDoc - Mac OS X

Warning: Only individuals with SecureDoc client administrative rights can successfully remove encryption and the client. ITS strongly recommends that department TSCs or administrative delegates supervise all decryption and client removal procedures. Decryption will take several hours or more and must be allowed to complete uninterrupted or catastrophic data loss may occur. Also, do not attempt to remove SecureDoc without fully decrypting any encrypted drives, in which case catastrophic data loss may occur.


  1. SES Console access.
  2. Local administrative access to the device where SecureDoc is to be uninstalled.
  3. Active network connection.

Enable Decryption

Ensure that the SecureDoc account logging in to the host computer has administrative rights for the SecureDoc client. If not, assign them.

  1. Open the SES Console, locate the Device Name.
  2. Right-click on the logged in user listed as having access to the device.
  3. Select Access Rights as shown below. The resulting pop-up will display all privileges for the selected user.

  4. If the selected account does not have administrative access to this device, assign admin privilege by simply selecting the Admin Rights radio button. Alternatively you may select Convert Hard Disk which is the only privilege necessary to perform decryption.

  5. Click OK.

The SES server will communicate access rights changes to the device automatically, however we recommend initiating client communication with the server to ensure the update is received.

Within several minutes the access rights change is complete, but the computer must be rebooted for the change to take effect.

Decrypt & Uninstall

Restart the Mac and interrupt autoboot by tapping the F10 key after the SecureDoc "keys" icon appears. The window to interrupt autoboot is brief; if missed, hard power off and try again. When the SecureDoc Owl screen appears, authenticate to pre-boot with the account having access rights as listed in Step 1 by entering the account name and password.

  1. Log in to the computer with the account having its access rights modified in Step 1 above.
  2. Locate the SecureDoc folder in Applications/WinMagic/SecureDoc.
  3. Execute the SecDocUninstall app located within the SecureDoc folder.

  4. Enter local administrative account credentials if prompted by Mac OS X.

  5. Confirm the uninstall request.

  6. Enter your SecureDoc account password (i.e. the same password used to authenticate at pre-boot).

  7. Reconfirm the uninstall request.

  8. Wait for disk decryption to complete. (Tthis process may take quite some time and should not be interrupted).

  9. Reboot!

Hard drive data is no longer protected by SecureDoc.
