There is no 32-bit version of Java 8 for OS X so he is either not using Java 8 or he is not running in 32-bit mode. The “QT_Movie_Opener” plugin (File>Import>Using QuickTime command) requires QuickTime for Java, which requires a 32-bit version of Java, so he will need to be using Java 6, which does has a 32-bit version. Note that OS X 10.10 (Yosemite) does not include QuickTime for Java. Instructions for installing it can be found at <http://imagej.nih.gov/ij/docs/install/osx.html>.
