有几件事情可以让Windows笔记本电脑和MacBook 区(MacBook)分开来。其中之一是软件更新(Software Update)。每个操作系统更新都会带来重要的安全补丁以及高级功能。这有助于用户升级他们使用的设备的体验。macOS 更新过程简单明了。另一方面，Windows上的操作系统更新相当耗时。尽管下载新的 macOS 看起来很简单，但对于某些用户来说，它可能会在安装过程中出现问题，例如安装 macOS 时出错。在本指南的帮助下，我们可以确保解决 macOS 安装失败错误的可靠解决方案。
如何修复 macOS 安装失败错误(How to Fix macOS Installation failed Error)
macOS 安装失败的原因可能是：
-
繁忙的服务器(Busy Servers)：安装 macOS 时发生错误的最常见原因之一是Apple服务器负担过重。因此，您的下载可能会失败，或者可能需要一整天的时间来处理。
-
低存储空间(Low Storage Space)：如果您已经使用 MacBook 很长时间，那么您很可能已经使用了大量存储空间。存储空间不足将无法正确下载新的 macOS。
-
互联网连接问题(Internet Connectivity Issues)：如果您的 Wi-Fi 出现问题，macOS 软件更新可能会中断或出现 macOS 安装失败错误。
要记住的要点(Points to Remember)
- 如果您的 Mac 已使用五年以上(over five years old)，最好不要尝试更新并坚持使用您当前在设备上运行的Mac操作系统。新的更新可能会不必要地加重您的系统负担并导致灾难性错误。
- 此外，在选择系统更新之前，请务必备份您的数据。(back up your data)由于安装过程中的任何障碍都可能强制导致内核错误(Kernel error)，即MacOS反复重启，因为Mac卡在两个操作系统版本之间。
方法 1：检查日志屏幕(Method 1: Check the Log screen)
如果您注意到屏幕上的安装程序卡在下载过程中，那么下载实际上并没有卡住，看起来就是这样。在这种情况下，如果您单击十字图标(cross icon)，文件可能会下载不完美。要检查下载是否正确处理，请按照给定的步骤操作：
1. 在观察进度条的同时，按键盘上的Command + L 键(keys)。这将向您显示有关正在进行的下载的更多信息。
2. 万一下载卡住了，(download is stuck,)你会看到没有额外的文件正在下载。
方法 2：确保 Internet 连接(Method 2: Ensure Internet Connectivity)
许多用户都遇到了这个问题，因为他们的 Wi-Fi 连接不正确或DNS错误。在启动更新之前，请(Make)确保您的Mac处于在线状态。(Mac)
1. 通过在Safari(Safari)上打开任何网站来检查您的互联网是否正常工作。如果有问题，请重新启动路由器。(restart your router.)
2.刷新系统上的 Wi-fi ，方法是在(Refresh Wi-fi)Apple 菜单(Apple Menu.)中将其关闭然后再打开。
3.检查路由器 DNS(Check router DNS)：如果为您的Mac设置了自定义 DNS 名称(custom DNS names)，那么也必须检查它们。
4. 执行在线速度测试( online speed test)以检查您的连接强度。为清楚起见，请参阅给定的图片。

方法三：清空存储空间 (Method 3: Clear Storage Space )
如上所述，另一个常见问题是磁盘上的存储空间不足。我们的一般用法会占用磁盘上的大量空间。因此，当您的计算机空间较小时，安装程序可能无法正确下载，或者可能会触发安装 macOS 问题时发生错误。
注意：(Note:)您的计算机需要12 到 35 GB(12 to 35 GB)空间才能安装最新的 macOS Big Sur。
清理一些空间的快速方法是删除不需要的图片/应用程序，如下所示：
1.在您的设备上打开设置。(Settings)
2. 点击通用设置中的(General)存储(Storage)，如下图。
3.选择(Select the app)您要删除的应用程序，然后单击删除应用程序。(Delete App.)
方法 4：从 macOS Beta 版本取消注册
(Method 4: Un-enrol from macOS Beta Version
)
如果您的Mac(Mac)当前在macOS的Beta版上运行，则可能会阻止新更新的下载。从Beta更新中取消注册可能有助于修复 macOS 安装失败错误。这样做的方法如下：
1. 单击Apple icon > 系统偏好设置(System Preferences)。
2. 在这里，单击软件更新(Software Update)。
3. 现在，单击此 Mac 已注册 Apple Beta 软件计划下的(This Mac is enrolled in the Apple Beta Software Program.)详细信息(Details)选项。
4. 单击恢复默认值(Restore Defaults)以取消注册 Beta 更新。
这应该可以修复 macOS 安装失败错误。如果没有，请尝试任何后续方法。

Method 5: Download Installer via App Store/Apple 网站下载安装程序(Apple Website )
方法 5A：通过 App Store(Method 5A: Through App Store )
在某些情况下，人们报告说他们从系统偏好设置(System Preferences)下载更新时 macOS 安装失败。此外，仍在使用 macOS Catalina的用户抱怨说：当他们尝试通过软件更新(Software Update)更新他们的 macOS 时，屏幕上找不到请求的 macOS 版本(the requested version of macOS couldn’t be found)。因此，您可以尝试从App Store下载软件来修复 macOS 安装失败错误。(fix macOS installation failed error.)
1.在 Mac 上启动App Store 。
2.在这里，搜索相关更新；例如：macOS 大苏尔。(macOS Big Sur.)
3. 检查所选更新与您的设备型号的兼容性(Compatibility)。
4. 单击获取(Get)，然后按照屏幕上的说明进行操作。
方法 5B：通过 Apple 网站(Method 5B: Through Apple Website)
为了停止接收此错误，也可以尝试直接从Apple 网站下载(Apple website.)Mac安装程序。(Mac) 两个安装程序之间的区别是：
- 从网站下载的安装程序会下载许多附加文件(additional files)以及所有 Mac 型号所需的数据。(data required for all Mac models.)这可确保更新已损坏的文件，并无缝进行安装。
- 另一方面，通过App Store或通过System Preferences下载的安装程序仅下载(System Preferences)与您的 Mac(to your Mac)相关的那些文件(files that are relevant) 。因此(Hence)，损坏或过时的文件没有机会自我修复。
方法六：通过MDS下载macOS(Method 6: Download macOS via MDS)
这是下载 macOS 更新文件的替代方法。MDS或Mac Deploy Stick是一个内置的Mac工具。此应用程序可以自动重新安装或卸载 macOS。
注意：(Note:) MDS应在 macOS 安装过程中下载并安装。
1. MDS App可通过各种开发者的网页获得，首选的是TwoCanoes 的 MDS。(MDS by TwoCanoes.)
2. 单击免费下载(Free Download)并运行安装程序。
3. 启动MDS 应用程序(MDS App )并选择您希望在Mac上下载和安装的(Mac)macOS 版本(macOS version)。
您应该能够下载上述更新而不会遇到 macOS 安装失败错误。如果没有，请尝试下一个修复。

方法七：开启内容缓存(Method 7: Turn On Content Caching)
修复 macOS 安装失败错误的另一种技术是打开内容缓存。此功能减少了成功下载所需的带宽，并有助于加快安装过程。一些用户可以通过打开此功能来减少下载时间。按照给定的步骤执行相同的操作：
1. 单击Apple 菜单(Apple menu)并选择System Preferences。
2. 点击共享(Sharing )选项，如图所示。
3. 单击左侧面板中的内容缓存(Content Caching)，如下图所示。
4. 在弹出菜单中，确保：
-
缓存大小(Cache Size )是无限( Unlimited)的，并且
-
选择所有内容(All Content)。
5.重新启动Mac(Restart the Mac)，然后尝试安装。
方法 8：以安全模式启动 (Method 8: Boot in Safe Mode )
此方法是关于在安全模式下(Safe Mode)继续安装。幸运的是，在这种模式下，所有后台下载和启动代理都被阻止，这往往会促进 macOS 安装成功。要以安全模式(Safe Mode)启动Mac，请按照给定的步骤操作：
1. 如果您的计算机已打开(switched on)，点击屏幕左上角的Apple 图标。(Apple icon)
2. 选择重新启动( Restart)，如图所示。
3. 重新启动时，按住Shift 键(Shift key)。
4. 看到登录屏幕后，您可以松开(release)Shift 键。
这应该可以修复 macOS 安装失败错误。(This should fix macOS installation failed error.)
方法 9：重置 PRAM 设置(Method 9: Reset PRAM Settings)
重置PRAM设置是解决与操作系统相关的任何问题的绝佳选择。PRAM和NVRAM存储重要设置，例如显示器的分辨率、亮度等。因此，重置PRAM和NVRAM设置也可能有助于修复避免安装 macOS 时发生的错误。这样做的方法如下：
1.关闭(Turn off )MacBook。
2. 现在，按下电源按钮(Power button)将其打开。
3. 按键盘上的Command + Option + P + R键。
4.看到Apple标志出现后松开按键。(Release)
注意：(Note:)在此过程中 ，Apple 标志(Apple logo)会出现和消失三次。(thrice )
5. 之后，MacBook 应正常重启(reboot )，设备安装应无故障。

方法 10：以恢复模式启动 Mac(Method 10: Boot Mac in Recovery Mode)
修复 macOS 安装失败错误的另一种故障排除方法是登录到恢复(Recovery)模式，然后继续安装。
注意：在切换到恢复模式进行软件更新之前，(Note:) 请(Make)确保Mac已连接到稳定的互联网连接。
1.如前所述，单击Apple 图标(Apple icon)>重新启动。(Restart)
2. MacBook重新启动时，按住键盘上的Command + R keys。
3. 等待大约20 秒(20 seconds)或直到您在屏幕上看到Apple 标志。(Apple logo)
4. 成功登录恢复模式后，使用Time Machine 备份(Time Machine backup)或安装新操作系统选项(Install the new OS option)以正常处理更新。
方法 11：使用外部驱动器(Method 11: Use External Drive)
此方法比本指南中提到的所有其他故障排除方法要复杂得多。但是，如果您有足够的头脑，您可以尝试使用外部驱动器作为可启动媒体(using an external drive as bootable media)来下载您的软件更新。
方法 12：联系 Apple 支持(Method 12: Contact Apple Support)
如果上述方法均无法解决此问题，请联系Apple 支持(Apple Support)以获得进一步的指导和支持。您可以访问您附近的Apple Store或通过他们的官方网站与他们联系。
