DSS player cannot open because of install from an unidentified developer

Asked By 0 points N/A Posted on -

Hi there,

I have this error when I want to install Olympus DSS player V7 on my laptop with Mountain Lion OS. A friend of mine uses Olympus without a problem and I think I am the only one who has this kind of error. Any solution for this error ? Can this error be solved ?

Thanks !



“DSSPlayerV7.mpkg” can’t be opened because it is from an unidentified developer.

Your security preferences allow installation of only apps from the Mac App Store and identified developers.

“DSSPlayerV7.mpkg” is on the disk image

“DSSPlayerV731Update.dmg”. Google Chrome downloaded this disk image today at 2:38 PC from www.olympus.com.au.

DSS player cannot open because of install from an unidentified developer


The error is caused by changes made to the Mac operating system version 10.8 (Mountain Lion).  A program called GateKeeper is used to help protect the Mac user from installing software from anywhere; Apple would prefer users to download apps from the Mac App Store.  This keeps the user’s hardware and software guaranteed to be safe.

In Mountain Lion OS X 10.8 newly installed security features were introduced which allows a user to state which software is allowed to be installed on his/her Mac.  Currently, Olympus falls into the category of developer where no digital certificate is registered with Apple.  Essentially this means it is “use at your own risk” software.

The workaround to the error you are experiencing is to do the following:

  1. While installing the Olympus DSS Player software, go to “System Preferences”>”Security & Privacy” and change the “Allow Applications downloaded from:” setting to “Anywhere” as I have indicated below
  1. As soon as you have changed the settings as above, run the installer for Olympus DSS Player
  2. Please remember to change the settings back to “Mac App Store” or “Mac App Store and Identified Developers” after you have completed the installation
