![]() In AppleScript, you can launch an app using two different commands By default, open looks in the top-level Applications folder if the app is installed somewhere else, you will need to provide its full pathname. That doesn’t work with proper apps, for which you must use the open command with its -a option:įor instance. In Terminal, you would normally run a command tool by simply typing its name and options, as in the above examples. If Gatekeeper cannot find a valid signature, it will only offer you the option to open the app if you use Finder’s menu command, and not after a double-click, for example. They are not identical: Gatekeeper checks downloaded apps’ signatures when they are first run. In the Finder, you can double-click its icon or use a launcher such as the Dock, or merely select its icon and use the Finder’s Open command. Opening and running an app is also easy to achieve in many different ways. Just as AppleScript can call shell commands, so you can execute AppleScript from the command shell, using the command osascript: to understand all its options, read its man pages using man osascript. Rough equivalents using halt and reboot are These are handy because they can be called by an AppleScript, using its do shell script command, with the authentication option:ĭo shell script "shutdown -r now" with administrator privileges In both cases, you will then have to authenticate with your admin password. You can achieve the same thing in Terminal by typing But if you just want a quick return to where you are now, use Control-Command-Power button (restart) or press and hold the Power button (shutdown). The preferred keystroke commands are Control-Command-Eject (to restart) and Control-Option-Command-Eject (to shut down), as they close all open apps in an orderly fashion first. There are subtle differences between some of them. Even something as simple as shutting down or restarting can be initiated using the Finder’s menu commands, with keystroke commands, forced using the Power button, or with the shutdown or reboot commands in Terminal. For many of its features, macOS offers you several different ways of doing the same thing.
