For users on Mac OS X 10.8.4 and later, rather than sending a .jnlp file to launch the Blackboard Collaborate web conferencing client, the service will send a new .collab file when a user attempts to join a Blackboard Collaborate web conferencing session. The Blackboard Collaborate Launcher is a utility that knows how to unpack the .collab files and then run them using a known and stable version of Java (which is provided by the launcher itself). The first time that a .collab file is to be sent to a user, the system will present a dialog that instructs them to download the Blackboard Collaborate Launcher so that they can join a Blackboard Collaborate web conferencing session.
Once the Blackboard Collaborate Launcher is installed, a user simply has to double-click on the .collab file that is downloaded to their system when they attempt to join a web conferencing session. The Blackboard Collaborate Launcher will then unpack the .collab files and launch the session.
Detailed instructions about setting up the Collaborate Launcher for the following browsers can be found below.
Additional information about launching Collaborate sessions on Mac OS X can be found at Blackboard Collaborate's Support Portal.
