Just a word of warning for anyone upgrading on MacOS X to Yosemite. I've personally found that when Boxcyptor is setup to use Spotlight it will have issues after the upgrade. You will need to disable Spotlight in the Boxcyptor Preferences order to prevent it spinning out and consuming endless amounts of RAM. I've not tried re-enabling it yet, but assume that it might force a re-build of the index and therefore become stable again.
Yosemite has major changes to Spotlight.
Version: 2.1.411 and OS X 10.10
