Run script on suspend/resume in Mac OS X

Question

Is there any way to automatically run a script on suspend/resume (i.e. when I close the lid, or after opening it) under Mac OS X 10.4?

Answer 1

I don't know, but you'll get better results googling for the terms "Sleep" and "Wake" -- those are the canonical Apple names for suspend and resume.

Answer 2

Maybe try Sleepwatcher. Can't vouch for it, but found it after following Kevin's tips:

SleepWatcher 2.0.5 (now compatible with Mac OS X 10.5 “Leopard”) is a command line tool (daemon) for Mac OS X that monitors sleep, wakeup and idleness of a Mac. It can be used to execute a Unix command when the Mac or the display of the Mac goes to sleep mode or wakes up or after a given time without user interaction. It also can send the Mac to sleep mode or retrieve the time since last user activity.

Answer 3

I believe SleepWatcher can provide the functionality you are looking for.

Answer 4

Here's another one that should do at least half of what you want: On Wake.

Answer 5

Depending on the problem you're trying to solve, launchd might work. It will run tasks that were scheduled while the machine is asleep when it wakes up. It's also smart enough to only run one instance of the task if several intervals have passed while the machine was asleep.

See Getting Started with launchd from Apple.
