Mac OS X loses file association for ICA files

MISSING OPTION FOR CITRIX ONLINE PLUG-IN

I had a user who recently purchased an iMac and wanted to access the corporate published desktop via our Citrix Access Gateway. Unfortunately, whenever he would try to launch the hyperlink for the desktop VMware Fusion would load.

I verified that the Citrix client for Mac OS X was installed from the link here. After a reinstall however, the behavior continued. Even uninstalling Fusion did not help, instead displaying a [null] result. Creating an *.ica file on the desktop, right clicking and choosing 'Open With', there was no other option than the file association for VMware.

RESOLUTION

  1. Launch /Library/Application Support/Citrix/Citrix online plug-in.app <- This creates a new option in the launcher user file for Citrix
  2. Create an *.ica file and Command + I to get info
  3. In the 'Open with:' section, choose 'Citrix online plug-in' as the option
  4. Click 'Change All...'
CONSIDERATIONS

Snow Leopard includes a 64 bit version of Safari and earlier builds of the Citrix online plug-in (v 11) were not compatible so make sure you have the latest and greatest installed.

Unlike Windows, File Associations are not centrally managed through the GUI. There are 'dirtier' ways to change the user account's file associations through the Terminal; this is the safest and easiest way however.
