  Zoom is a different creature entirely. The green button used to be zoom in OS X, and you can still access zoom by holding down Option and clicking the green button.
  Zoom on a Mac takes the window to its optimal largest size. So it may not fill the whole screen, but will rather take up as much space as it should.
• maximize 最大化: Control + Command + f（罕用）
• minimize 最小化：Command + M（罕用）
• restore 恢復(fù)：Alt + Green Button（access zoom by holding down Option and clicking the green button）.

  Your Mac system displays its uptime in the System Information window. Click the Apple menu icon on the bar at the top of your screen, hold down the Option key, and click System Information. Scroll down in the left pane, select Software, and look for System Software Overview: Time since boot to see your Mac’s uptime.
  or: Open a Terminal window, run the uptime command.
