QTJ manual installation under OS X Yosemite and El Capitan
The default installation of OS X Yosemite (OS X 10.10) and greater does not include key files required for compiling and running plugins that require QuickTime for Java. After downloading ImageJ, if Java has not been installed, you will be asked to download and install Java. Once Java is installed, the following additional steps are needed:

(1) Install QTJava.zip and libQTJNative.jnilib: Copy the files QTJava.zip and libQTJNative.jnilib into ~/Library/Java/Extensions, where “~” is your home directory, or if you have administrative privileges, you can install these for all users into /System/Library/Java/Extensions. Yosemite hides the ~/Library folder by default, so you will need to open your home folder and check “Show Library Folder” in the View/Show View Options dialog.

(2) Install QuickTimeJava.bundle: Download QuickTimeJava.zip. Extract and copy the folder QuickTimeJava into either /System/Library/ or ~/Library. For some reason, recreating the folder and copying QuickTimeJava.bundle into that folder doesn't work for me.

Support for further development of some of these plugins was provided through a software development supplement to a grant from the National Institutes of Health and an equipment supplement to a grant from the National Science Foundation
