"Verifying Tableau" Message Persists and Install Does Not Complete

Issue

When installing Tableau Desktop on a Mac, the below message displays, and install does not complete:

Verifying "Tableau"

Verifying Tableau

Environment

Tableau Desktop
Mac OS

Resolution

Option 1 - Open Tableau Desktop with full permissions.

Right-click (or Control-click) Tableau Desktop and choose Open
When the "Are you sure you want to open it?" warning displays, choose Open again.

Option 2 - Open the installation package from inside the installer tool

From the Finder in Mac OS X, hit Command + Shift + G and enter the following path: /System/Library/CoreServices/
Locate the app named “Installer.app” from this directory and launch it directly
Navigate to the .pkg file that is stuck on verifying and select to open it.

Cause

Mac OS X Gatekeeper is preventing Tableau Desktop from launching.

Additional Information

If no "Open" option is available, go to System Preferences to change the Gatekeeper options.
