Email instructions to your Mac
£2.29 Developer ACT Productions, actproductions.net Requires OS X 10.8 or higher
This clever app lets you trigger scripts on your Mac with an email. You can do something similar by making a rule in Mail to trigger an AppleScript, but Actuator is smarter and more flexible, and lets you trigger Automator workflows, too.
It effectively runs as a standalone email client, checking an account in the background. When you send an email to that account with a particular word in the Subject field and the full name of one or more scripts you’ve copied to its folder in the body, those scripts will run. It can also post notifications, and because it’s running as an email client, can reply to you to report status, or list the available scripts if you’ve forgotten what they are, and delete the trigger email.
There are some example scripts – restart, unmount all drives, clean Safari history and more – but the app is likely to be daunting to less confident users, and there are some rough edges. Christopher Phin Slightly more friendly than using Mail and AppleScript, but still only for the technically-minded.
