How to create a log file to troubleshoot problems with Prism Mac.

Last modified July 2, 2014

When Prism starts, it goes through many steps to initialize everything. A log file lets us see all these steps, and spot any problems. The log file also logs some later steps, so it can help diagnose reasons for Prism crashing or freezing, or any other problem.

With Prism 6.0c and later, Prism keeps logging even after it starts up, and this can slow things down. So be sure to turn off logging once it is no longer needed.

If you use 7.0c or later

Starting with Prism 7.0c, Prism always logs startup, so you can always send us a startup log to diagnose issues with Prism launching. Even if Prism doesn't successfully launch, the log file will be created (at the location explained below) and will be useful to troubleshoot.

You can enable extended logging via an option on the Services tab of the Preferences dialog. After doing this use Prism normally to try to reproduce whatever problems you have. Then send us the log. Then turn off extending logging which can slow Prism down.

The log file will be created at ~/Library/Logs/GraphPad. You can click "Show in Finder" to go directly to the file. 
Note: This is the Library folder in the users profile.  Don't confuse it with a similarly named path from the root Library folder (it does not contain the GraphPad folder.)   The Library folder in the user profile may be hidden by default. Learn how to make these files and folders visible. 

Follow these steps to create a log file for Prism 7.0a, 7.0b and Prism 6 for Mac: (See this article for Windows).

  • Create a text file named prism-config.xml (for Prism 6, the name should be StartupConfig.xml) with the following contents. Use TextEdit (or some other text editor) to create the file. Do not use a word processor. Programs such as Pages tends to add lots of formatting detail to the file. Save as plain text (not rich text) If you try to save as an XML file type, the program you use will probably add a lots of junk to the file.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <startup-log>true</startup-log>
</configuration>
  • Alternatively, download this file and place it into the appropriate folder. 
  • Place the file in the same folder as the Prism application, typically the Applications folder
  • Launch Prism
  • The log file will be created at ~/Library/Logs/GraphPad/
    Note: This is the Library folder in the users profile.  Don't confuse it with a similarly named path from the root Library folder (it does not contain the GraphPad folder.)   The Library folder in the user profile may be hidden by default. Learn how to make these files and folders visible.
