Before this problem occurred I have been trying to defrag my disk using Drive Genius 3 and repair using disk utiltity. Than I decided to delete it. Not sure if that was the reason or not but after that I had this message pops up all the time "The application DGAgent quit unexpectedly". I have no idea what it is. This happens every I start up my iMac. The message pops up every time I click "ignore" "report" and "relaunch" buttons. Can you tell me what it is and how to fix it? Also this causes some of my applications such as Skype "cannot be opened because it is not supported on this architecture".

The error you're getting from Skype is because you're not using an Intel-based Mac. Skype only runs now on Intel-based Macs so I assume you're running a PowerPC iMac G5 or something are you? You also need to be running Leopard/Snow Leopard. Here's a screenshot of the System Requirements on the Skype Download page:

So, the Skype issue is not related to the DGAgent message.

As regards the startup of DGAgent on login, you can try the following:

  1. Open System Preferences
  2. Click Accounts
  3. Select your account
  4. Click Login Items
  5. Highlight Drive Genius if it's listed and click the '-' button on the lower left to remove it.

This will prevent OS X from attempting to start it on login. See screenshot below. enter image description here

  • @Jon No problem, did you try that? Did it work? Commented Jan 29, 2011 at 21:45
  • As for the login items, Drive Genius is not listed. I only have ItunesHelper and dropbox in the list. I removed both of them as well but it didn't work. The pop up still appears on screen.

  • Sorry yeah it will take a long time that's why I deleted it to see if I could figure out a quicker way. Press control+c to cancel it. I'll come back to you in a few minutes Commented Jan 29, 2011 at 21:58
