When I go to do the install I get the following error message included in this screenshot below. I quit ImageJ, restart it, go to Plugins, then Install. From there I select the .jar file. Am i installing this to the correct directory? It says it is the Plugin folder. I would appreciate any help you can provide.

You have run into the dreaded Mac OS Path Randomization “feature”, described in the third paragraph of the installation notes at https://imagej.nih.gov/ij/docs/install/osx.html.

MacOS 10.12 (Sierra) and later have a security feature called Path Randomization that can cause ImageJ to not work as expected. Path randomization is in effect if the "ImageJ home" path shown in the Image>Show Info window starts with "/private" and plugins are not installed in the Plugins menu. You can disable path randomization by dragging ImageJ.app to another folder and then (optionally) dragging it back.
