Tower Help & Support

Command Line Environment

When you run Git from the command line, it runs in the environment as set up by your Shell. GUI OS X apps, however, have no knowledge about your shell - and the PATH environment can be changed in many different places. The actual environment they run in even varies depending on how the application has been started:

  • From Spotlight
  • From Finder
  • From the Dock
  • From the Terminal with the open command (or our CLI Tool)

To provide you with a configurable environment, Tower supports defining environment variables in a custom file.

To make use of this, create a PLIST XML formatted file named environment.plist in ~/Library/Application Support/com.fournova.Tower3/.

A sample to define your path could look like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "">
<plist version="1.0">

You can add additional key-value pairs as needed.
If your hook script needs some variable to work properly, you can introduce it like this in the environment.plist


In case you're using a special authentication mechanism, like a smartcard (e.g. Yubikey), you can set this up here too. This should be similar to:


You can either use a text editor to create a Property List or Xcode, which provides a Property List Editor.
Please note that environment variables like $HOME aren't supported in the environment.plist. Also note that using relative paths might cause problems, which is why you should consider using absolute paths.

Restart after making changes
After modifying the environment.plist file, make sure to re-start Tower.
