Blackberry Link and Mac OS: WARNING
Own a Mac? Playing with a Blackberry 10 device?
DO NOT install Blackberry's Link software on a Mac!
Blackberry messed up a bit. There's a process called tunmgr that'll try to claim
99.9% (!!!!) of your CPU's power.
Uninstalling Blackberry Link will NOT solve the issue - which may lead you to believe that your Mac is at fault.
It's not. The uninstall just doesn't kill the process, as Blackberry's bloat-suite leaves all sorts of files and folders behind.
Anyhoo: should your Mac's fan go ballistic, open the Activity Monitor, find the tunmgr process, and then on the top left of the window hit "sample process". That'll show you the path to the nasty BB leftovers. Delete all that junk, kill the process, and then reboot your Mac. Problem solved.
