Do one of the following:
• Click the Nuke PLE dock icon.
• Open the Nuke application directory (by default, /Applications/Nuke8.0v7/), and double-click the Nuke8.0v7 PLE icon (or list item).
• Open a terminal, navigate to /Applications/Nuke8.0v7/Nuke8.0v7.app/Contents/MacOS, and enter ./Nuke8.0v7 --ple.
NOTE: On Mac OS X, you shouldn’t move the Nuke PLE bundle from its original installation folder as this prevents it from working correctly.
