If you are currently using BB Collaborate on a Mac OS, please be aware that you will be asked to download a new Launcher the next time that you attempt to enter a Collaborate session. This feature fixes the Mac OS Java problem that many users experienced this Spring and Summer. This does not affect Windows users.
