How to set sourcetree's default terminal to iTerm?
Solution 1:
Here is the same issue on the Windows client.
It is not possible. However, you could add a custom action to open iTerm:
You can add a custom action in the menu. From the global options go to Custom Actions tab and add an action to Open in Terminal using the console you want. This isn't quite as cool as just hitting the terminal icon, but you can easily accomplish the same outcome.
With iTerm2, there are some things you could try to override the default terminal system wide. If that works it might be better than using a custom action.
