MacOS – way to shut down, restart or log off without seeing the popup

macos

I would like to know if there is a way to delete the popup shown when you are trying to shut down, restart or log off your Mac with version OS X 10.9 – What I want is that when I click on one of these buttons, the computer makes that action without asking for a confirmation and the countdown of 1 minute.

I know you can use Alt+Shut down/Restart/Log off but I would like to know if there is a direct way to deactivate that popup via Terminal or something else.

There are a few methods to shutdown without confirmation (this will not remove the confirmation from the original method):

In Terminal: shutdown -h now, but this force quits all applications
Make an Applescript and save it as 'Application,' save it somewhere easily accessible, but not prone to accidental clicks:
```
on run
  do shell script "shutdown -h now"
end run
```
The shortcut Control-⌥ Option-⌘ cmd-⏏ Eject
Clicking shutdown with ⌥ Alt / ⌥ Option held down (as you said)
If using Alfred, you can summon the Alfred window and start typing "Shut down" or "Restart" and then pressing Enter. No Power Pack needed, no force quits, no dialog and no countdown.

You could also try following this method by WZZZ, but I haven't checked if it works. It reduces the time to auto-quit apps, so do:

defaults write org.x.X11 wm_auto_quit_timeout -int x

MacOS – way to reduce the swappiness of OS X 10.6 Snow Leopard

I'm not sure that a swap file of 2MB to 25MB is really something to worry about. It might be more useful to look at the values for Page In and Page Out to determine how often data is being written to the swap. The number of page events can be found using the System Memory tab of the Activity Monitor application.

There are a couple of other options that you could try but I think you're probably way out of warranty if you try:

I would just suggest putting up with the existing system since the wear on your SSD is probably minimal especially since SSD wear is a bit of a myth anyway or maybe it's not.

MacOS Scripts – Making Script/App Run on Logout

Logout hooks were deprecated in 10.4, but they still work as of 10.9.

sudo defaults write com.apple.loginwindow LogoutHook ~/.logouthook
echo $'#!/bin/bash\nsay a' > ~/.logouthook
chmod +x ~/.logouthook

The value of the LogoutHook key can only be a path to an executable and not a shell command. The logout hook is run as root.

The defaults command modifies /var/root/Library/Preferences/com.apple.loginwindow.plist. Adding a LogoutHook key to /Library/Preferences/com.apple.loginwindow.plist doesn't work.

If a logout hook takes long enough to run, a gray screen is shown until the logout hook terminates. There doesn't seem to be any time limit after which logout hooks are forced to terminate.

I haven't figured out any way to run programs on logout reliably with launchd. When I tried trapping signals like EXIT, the code in the trap was only run when I logged out to the login window and not when I shut down or restarted.
