The "Control + Alt + Delete" key combination on a Mac does not do the same task as it does on a Windows computer. To access the Task Manager, log off, restart, or shut down a Windows computer, press "Control + Alt + Delete." The "Control + Alt + Delete" key combination has no default actions on a Mac. This key combination may act in specific circumstances since some apps or utilities may have given it a specific function. If you want to perform tasks similar to those that can be done with "Control + Alt + Delete" on a Windows PC, you can use the following key combinations on a Mac: "Command + Option + Escape" to open the Force Quit window, which allows you to force-quit a frozen app. "Command + Control + Power button" to put the Mac to sleep. "Command + Option + Control + Power button" to restart the Mac. "Shift + Control + Power button" to shut down the Mac. Remember that certain key combinations might not function in all circumstances and that some apps or utilities might have alternative key combinations or menu options for carrying out the same functions. For further information about its key combinations and menu options, refer to the application's or utility's documentation.
