Issue

Tableau Prep Builder performs very slowly and/or stops responding on a Mac running Mac OS Mojave. 
 

Environment

  • Tableau Prep Builder 2019.1.1
  • Mac OSX (Mojave)

Resolution

  1. Run the following command in terminal to check the current hostname, and note it down in case you want to reverse the change:
    hostname
  2. Run the following command to change the hostname to "localhost":

    scutil --set HostName "localhost"

  3. Restart Tableau Prep Builder and verify that the issue no longer occurs.

Cause

Hostnames other than "localhost" can cause performance issues for some software, including Tableau Prep Builder.
