macos 版本_如何检查您使用的macOS版本

macos 版本

Apple releases new versions of the macOS operating system about once per year. Here’s how to check which release of the macOS operating system is installed on your MacBook, iMac, Mac Mini, or Mac Pro.

苹果大约每年发布一次新版本的macOS操作系统。这是检查MacBook，iMac，Mac Mini或Mac Pro上安装了哪个macOS操作系统版本的方法。

To find this information, click the Apple icon on the menu at the top left corner of your screen, and then select the “About This Mac” command.

要查找此信息，请单击屏幕左上角菜单上的Apple图标，然后选择“关于本机”命令。

The name of the macOS release you have installed appears on the Overview tab in the resulting window. The precise version number of your installed operating system appears below that.

您已安装的macOS版本的名称出现在出现的窗口的Overview选项卡中。您安装的操作系统的确切版本号显示在其下方。

In the screenshot below, we’re using macOS High Sierra, which is version 10.13. The version number says “10.13.4” because we’ve installed the latest security updates. These smaller updates are available from the “Updates” tab in the Mac App Store app.

在下面的屏幕截图中，我们使用的是macOS High Sierra，版本为10.13。版本号显示为“ 10.13.4”，因为我们已经安装了最新的安全更新。这些较小的更新可从Mac App Store应用程序的“更新”选项卡中获得。

Note: If you’re using an older version of the Mac operating system, it may be called “OS X” instead of macOS.

注意：如果您使用的是较旧版本的Mac操作系统，则可能将其称为“ OS X”而不是macOS。

If you’re not using the latest version of macOS, you can install it from the Mac App Store—assuming your Mac’s hardware is still supported by Apple. To do this, click the “Software Update” button in the About This Mac window, which will open the Mac App Store. You can also launch the Mac App Store in another way—for example, by clicking its icon on your dock.

如果您未使用最新版本的macOS，则可以从Mac App Store安装它-假设Apple仍支持Mac的硬件。为此，请在“关于本机”窗口中单击“软件更新”按钮，这将打开Mac App Store。您还可以通过其他方式启动Mac App Store，例如，通过在扩展坞上单击其图标。

You can download and install the latest release of macOS on your Mac right from the app. We encourage you to back up your Mac before continuing, though—just to be safe.

您可以直接从应用程序在Mac上下载并安装最新版本的macOS。不过，为了安全起见，我们建议您在继续操作之前先备份Mac 。
