Syntax Highlight does not work properly

[GreatOom]

The syntax highlight extension "SyntaxHighlight_GeSHi" is already pre-installed in the macOS MediaWiki App (I use Bitnami). This is great.
I changed my "LocalSettings.php" file and added the line

wfLoadExtension( 'SyntaxHighlight_GeSHi' );

After a restart of the services it works only partly. This means for example

<syntaxhighlight lang="xml" line="1" style="border:3px dashed blue">
<dict>
<key>Label</key>
</dict>
</syntaxhighlight>

Shows the gray area and a dashed blue border. It does not colorize the code.

Any clue what's wrong? What did I miss?

Lack of highlighting generally indicates that the call to pygments is failing for some reason or another. You may wish to temporarily enable debug logging to better understand why this is happening. Chances are the issue lies with your choice of OS: I believe that the extension only ships a linux binary of pygments, but not a mac binary. You may need to install pygments separately and point to it via $wgPygmentsPath.
