If you installed the software and restarted InDesign, and nothing happened, it is most likely because InDesign did not recognize the plug-ins at all. InDesign usually fails to recognize the plug-ins because they lack execute or read permissions, or the OS X file type has been lost.
These issues usually occur when the TripleTriangle folder was copied across a network file server unzipped.
To fix the issue, try downloading your deployment zip file directly to the destination Mac. Or, copy that file across the network zipped, and unzip it locally.
