Slow Performance When Launching or Connecting to Flat Files After Upgrading to macOS Sierra

Issue

After upgrading to macOS Sierra, Tableau Desktop is slow to launch. The following behaviours occur:
  • The icon bounces in the task bar before launching. 
  • Tableau Desktop is slow to connect to flat files, the following message is displayed: ​"Loading data source for the first time..."

Environment

  • Tableau Desktop 9.3 and later versions
  • macOS Sierra 10.12

Resolution

Option 1

Upgrade to Tableau Desktop 10.1.7, 10.0.9  or 9.3.15. For more information, see Upgrading Tableau Desktop.

Option 2

Edit the hosts file on the Mac to include your computer's local network name at the end of the "127.0.0.1 localhost" line. To find your local network name,
  • Choose Apple menu > System Preferences.
  • Click Sharing.
  • Your computer’s local network name is displayed beneath the computer’s name at the top of Sharing preferences, labeled with dashes as:
Computers on your local network can access your computer at:
Example-MacBook-Pro.local 

Using that example, add your computer's local network name to the end of the 127.0.0.1 line of the hosts file like so:
127.0.0.1 localhost Example-MacBook-Pro.local

Cause

The local network name and the name associated with the 127.0.0.1 IP address are not the same. This behavior is related to a known issue (ID: 614537) that has been fixed in a later version of Tableau Desktop.
