- MacBook Air（2015 年或更新版本）
- MacBook（2016 年或更新版本）

如何检查您拥有的 macOS
版本(Version)
要检查您的 macOS 版本，请单击桌面左上角的Apple菜单，然后选择 About This (Apple)Mac。概览(Overview)选项卡显示您机器上安装的 macOS 版本的版本号和名称
。
如何更新到最新版本(Latest Version)的 macOS
有多种方法可以在您的笔记本电脑或台式机Mac上更新到最新的 macOS 版本。在更新之前，请使用Time Machine(Time Machine)、iCloud 或其他第三方应用程序（例如Carbon Copy Cloner）备份您的计算机。您可以转到Apple菜单 > 关于本机，然后单击软件(Mac)更新(Software Update)以使您的计算机检查 macOS 更新。
或者，您可以前往Apple menu > System Preferences > Software Update。您会看到您的计算机正在寻找最新版本的Mac操作系统。
完成检查后，您可以单击“立即升级(Upgrade)”或“立即更新”开始下载和安装更新。您的Mac可能会自动重启以完成新版本 macOS 的安装，即使它是带有一些安全更新的次要版本。
直到几个版本之前，macOS 更新都出现在Mac App Store中，但现在已经改变了。您可以使用上述方法查找最新版本的 macOS。
macOS 版本号的含义
每个版本的 macOS 都有一个与之关联的数字。此前苹果(Apple)将操作系统称为Mac OS X，其中 X 发音为 10，主要操作系统的版本号会反映这一点。每个新更新都使用了一个数字，例如 macOS 10.13 用于 High Sierra和 macOS 10.15 用于Catalina。
新的 macOS 版本号系统每年都会更改第一个数字，并在小数点后添加额外的数字来表示该版本号内的次要或主要更新。例如，macOS 11 是Big Sur，macOS 12 是Monterey，macOS 12.3 是引入通用控制(Universal Control)功能的软件更新。
此版本编号系统类似于 iOS 或 iPadOS，您可以分别在 iPhone 或 iPad 上找到它们。
暗模式、SharePlay和其他主要功能更新等大功能发布通常是为新版本的 macOS 保留的。较小(Smaller)的小数点版本号更新更有可能包含安全更新、错误修复，有时还会更新Safari浏览器或其他Apple应用程序。

The Latest Version of macOS is macOS Monterey
The latest stable version of Apple’s Mac operating system is macOS 12 Monterey. At the time of writing, the latest version number for macOS Monterey is 12.4.
Apple announces new macOS versions at the WWDC (Worldwide Developers Conference) keynote every year. The company unveiled macOS Monterey at WWDC in June 2021 and released it to the public in October 2021. The latest update introduced features such as SharePlay, AirPlay to Mac, Shortcuts for macOS, and Universal Control.
If you’re wondering if your Mac is compatible with macOS Monterey, here’s the complete list of devices that support the latest release of macOS:
- MacBook Pro (2015 or newer)
- MacBook Air (2015 or newer)
- MacBook (2016 or newer)
- Mac mini (2014 or newer)
- iMac (2015 or newer)
- iMac Pro
- Mac Studio
- Mac Pro (2013 or newer)
If you have an older Mac, you may have to use an older version of macOS.
How to Check What Version of macOS You Have
To check your macOS version, click the Apple menu in the top left corner of the desktop and select About This Mac. The Overview tab shows the version number and the name of the macOS release installed on your machine.
How to Update to the Latest Version of macOS
There are multiple ways to update to the latest macOS versions on your laptop or desktop Mac. Before you update, back up your computer using Time Machine, iCloud, or alternative third-party apps such as Carbon Copy Cloner. You can go to the Apple menu > About This Mac and click Software Update to make your computer check for macOS updates.
Alternatively, you may go to Apple menu > System Preferences > Software Update. You’ll see your computer looking for the latest version of the Mac operating system.
When it’s done checking, you can click Upgrade Now or Update Now to begin downloading and installing the update. Your Mac may automatically restart itself to finish installing the new version of macOS, even if it’s a minor version with some security updates.
Up until a few versions ago, macOS updates appeared in the Mac App Store, but that has changed now. You can use the methods described above to find the latest version of macOS.
What macOS Version Numbers Mean
Each version of macOS has a number associated with it. Previously Apple used to call the operating system Mac OS X, where X is pronounced as 10, and the version numbers for major operating systems would reflect that. Each new update used a number such as macOS 10.13 for High Sierra and macOS 10.15 for Catalina.
The new macOS version number system changes the first number each year and adds additional digits after the decimal to denote minor or major updates within that version number. For example, macOS 11 is Big Sur, macOS 12 is Monterey, and macOS 12.3 was a software update that introduced the Universal Control feature.
This version numbering system is similar to iOS or iPadOS, which you can find on the iPhone or the iPad, respectively.
Big feature releases such as dark mode, SharePlay, and other major functionality updates are usually reserved for new versions of macOS. Smaller decimal-point version number updates are more likely to feature security updates, bug fixes, and sometimes updates to the Safari browser or other Apple apps.
