Running actions depending on context?

Assuming what you want is for an action to happen automatically when ethernet is plugged in etc.

EventScripts is on the App Store and allows you to run actions when certain things happen. The list of supported events isn't enormous though, so you may have to be creative.

If you create an Automator routine (all drag and drop - no coding!) and save it as an app, then all you'll need is a one line shell script to launch from EventScripts:

Code:

/absolute/path/to/automator/script.app

I don't know if it's possible to do anything more specific without either bash, Applescript or Python. From a quick Google, PyMacAdmin looks like a contender for Python based event dispatching.

The "proper" way to do this (afaik) is to create a daemon. Your script can then run periodically and check if your conditions are true.
