Why do I get a Disk I/O error when I try to sign in to Skype for Mac OS X?

This article is also available for:

Sometimes, you may see a “Disc I/O error” when attempting to sign in to Skype:
“Disk I/O error. Quit and restart Skype. If you keep seeing this error, please contact Skype customer support.”

To resolve this issue, first make sure that you are using the latest version of Skype.

If the problem persists, we suggest uninstalling and reinstalling Skype:

  1. Quit Skype by ctrl-clicking the Skype icon and selecting Quit. If the Skype icon still appears in the Dock, ctrl-click the icon again, select Options, then click Remove from Dock.
  2. Move Skype from the Applications folder to the Trash folder.
  3. Open Finder from the Dock, and press Command+Shift+G.
  4. In the pop-up window that appears, type ~/Library/Application Support/, then click Go.

Then, to reinstall Skype and keep your chat history:

  1. Rename the Skype folder in ~/Library/Application Support/ to “Skype.old”.
  2. Download and install the latest version of Skype.
  3. After the installation is complete, start Skype, then quit.
  4. In the Skype.old folder, find the folder with your Skype Name and copy it to the new Skype folder in ~/Library/Application Support/. Your chat history will be restored.

To reinstall Skype without keeping your chat history:

  1. Drag the Skype folder in ~/Library/Application Support/ to the trash.
  2. Ctrl-click the trash icon and select Empty Trash.
  3. Download and install the latest version of Skype.

If you’re still experiencing problems signing in to Skype for Mac OS X, please contact Skype Customer Service.
