Mac OS X is reporting that Snagit.app and SnagitHelper.app are using significant energy on the machine.
This problem has been addressed in Snagit 4.1.3 and later. Update by opening Snagit and browsing to the menu bar item Snagit > Check for updates.
This is a known issue that we are currently investigating. We hope to have a fix in a future release of Snagit.
