Sometimes restarting is not enough: you need to power off your Mac, wait for a little, and power it on again.

I'm looking for a script which does just that. Is it possible?

It could be a script which act like the "schedule" program in system preferences: it would switch off the Mac immediately, the add 1 minute to the current time and switch it on again.


Do you think it's possible?

    The following script seems to work properly under Mac OS X 10.7.3:


    set nextTime to ((current date) + 60)


    tell application "System Preferences"


        reveal anchor "Schedule" of pane id "com.apple.preference.energysaver"

        delay 0.1

        tell application "System Events"

            tell sheet 1 of window 1 of process "System Preferences"

                if value of checkbox 1 = 0 then click checkbox 1 -- Start up or wake

                click pop up button 2

                click menu item 3 of menu 1 of pop up button 2 -- Every Day

                set value of UI element 10 to nextTime

                click button "OK"

            end tell

            shut down

        end tell

    end tell

    I haven't tested this, so it may take some tweaking (I'm suspicious of the 'quoted form of' bits, because I don't know if pmset requires double quotes), but it should work.  basically it tells the power management system (pmset) to schedule a one-time shutdown in 1 minute and a one-time poweron in 2 minutes. 


    set shutdownTime to do shell script "date -v+1M '+%D %T'"

    set restartTime to do shell script "date -v+2M '+%D %T'"


    do shell script "pmset schedule shutdown " & quoted form of shutdownTime

    do shell script "pmset schedule poweron " & quoted form of restartTime


    If you have troubles it's almost certainly a matter of quoting.  it might be easier in that case just to rewrite it as a plain shell script.

    Just wondering... Is it possibile to have less than 1 minute? And how?

    See man date.  You can use -v+#S to specify seconds (e.g., -v+20S for 20 seconds), but keep in mind that there are sometimes non-negligible times involved, and I don't know what will happen if you try to schedule a shutdown or restart for a time that's already passed.  you could probably set shutdownTime to as little as 1 second in the future, but you'll need to account for the time it takes to finish shutdown in restartTime.

    thank you, it just make sense! so 1 minute is safer by now... ;-)
