MACOS MOJAVE 10.14 ON THE THINKPAD X220

关于MACOS MOJAVE 10.14安装版

With the release of macOS Mojave 10.14, Apple ended support for their own notebook models with specifications comparable to the ThinkPad X220.

随着macOS Mojave 10.14版发布，Apple停止对ThinkPad X220的'系统电脑型号'支持

Apple’s transition to the Metal graphics framework involved depreciating OpenGL and OpenCL. The Intel HD Graphics 3000 found in the X220 as well as MacBook Pro and MacBook Air models produced before 2012 is not compatible with Metal.

由于苹果在图形处理技术上弃用OpenGL和OpenCL而转向Metal,X220的英特尔HD3000处理器和MacBook Pro 及 MacBook Air之前的版本都与Metal不兼容

苹果弃用 OpenCL 和 OpenGL ，OpenCL 或遭全面淘汰
在 MacOS 10.14 的更新文档中，苹果表示使用 OpenGL 和 OpenCL 构建的应用可以继续在 macOS 10.14 中运行，但这些遗留技术在 macOS 10.14 中不推荐使用。现在使用 OpenGL 的游戏和应用应转向 Metal 。 同样，使用 OpenCL 进行计算任务的应用也应该采用 Metal 和 Metal Performance Shaders 。

Intel HD Graphics 3000是用在英特尔第二代酷睿系列处理器上的集成显卡。
Intel HD Graphics 3000是用在第二代酷睿处理器上的集成显卡，这一代集成显卡性能普遍较低，只能完成日常工作，对于3D游戏的支持比较欠缺。
核心显卡仍然和集成显卡一样需要耗费内存资源，所以用户使用核心显卡时需要2GB或以上的内存，由于HD3000核心显卡在与CPU协同工作时仍存在不兼容现象，使得其性能不能发挥到极致，所以市场上仍然有Core i3-2310M或2330M处理器屏蔽核心显卡而用GeForce GT520或GT540的搭配，有些高端笔记本使用双显卡交火模式也是为了使用独立显卡弥补核心显卡性能有限的不足，但是HD3000仍然可以满足普通用户的需求，如观看高清影音，一般文字处理和普通3D游戏，只是在大型游戏和发烧娱乐上明显不足。

While Mojave can run on the X220 by patching in graphics kexts from previous versions of macOS as detailed in the guides listed below, we believe the lack of native graphic support in Mojave makes this an appropriate time for us to stop creating new guides for installing macOS on the X220.

而Mojave可以通过在macOS的早期版本中打kexts补丁，从而在X220上运行系统。由于Mojave缺少原生图形支持，目前网站停止X220安装MacOS方法的更新。

We hope you understand this decision. All of our existing guides will remain where they are and we will continue to provide support for these versions of macOS on the X220 into the foreseeable future.

Wi-Fi card recommendations:

无线网卡的建议

Stock Wi-Fi cards in the X220 are not compatible with macOS

之所以安装BIOS破解版是因为X220中的无线网卡不能兼容macOS

Wi-Fi cards that require no configuration whatsoever and will work automatically in macOS:

以下无线网卡不需要任何配置就可以在macOS中运行(需拆机替换)

• Dell DW1510 – 802.11a/b/g/n 2.4 GHz & 5 GHz (Broadcom)
• Dell DW1515 – 802.11a/b/g/n 2.4 GHz & 5 GHz (Atheros)

For 802.11ac + Bluetooth as well as Continuity/Handoff support, it may be possible to make the AzureWave AW-CE123H (aka Dell DW1550) card work by following the steps in the guide here. Another guide that might be helpful is available here. Note that it will not be possible to boot from our standard USB installer with this card installed; only install this card after the macOS installation is complete and the necessary modifications have been made

至于网卡802.11ac + 蓝牙5.0和苹果的“设备互通支持”技术，你可以按照这个链接中的步骤来支持 AzureWave AW-CE123H (aka Dell DW1550)运作。

或者这个指南也是可行的。

请注意，安装此卡后正常的USB安装程序将无法启动，最好在macOS安装完成后再通过修改设置来安装此卡。

Various other Mini PCIe and USB Wi-Fi adapters compatible with macOS are listed here

建议事项

• If you are encountering restarts and kernel panics when resuming from sleep, try the following:
  1> confirm that Allow Bluetooth devices to wake this computer is checked on in System Preferences > Bluetooth > Advanced… and have at least one Bluetooth device connected to your X220 before putting it to sleep
  or
  2> disable Bluetooth in the BIOS under Security > I/O Port Access > Bluetooth
  or
  3> use the workaround created by tluck in the T420 guide here
  We are attempting to develop a better solution for this issue.

• 如果电脑从睡眠恢复时发生系统奔溃，请尝试以下操作

  1>确保 Preferences > Bluetooth > Advanced… 中的"Allow Bluetooth devices to wake" 已经勾选，并且确保你的x220在睡眠前至少已有一个蓝牙设备连接

  2>禁止Security > I/O Port Access > Bluetooth 下的BIOS中的蓝牙设备

  或者

  3>使用t420中tluck创建的解决方案

• If Bluetooth is not available after waking from sleep, toggle the wireless radio switch on the left side of the computer off and then on again

• 如果电脑从睡眠中恢复后蓝牙是不可用的，关掉电脑左边的无线按钮然后再打开

• If you encrypt your boot drive with FileVault it will be necessary to connect a USB keyboard when booting to input your password. An EFI driver for the built-in X220 keyboard is not yet available.

• 如果你用FileVault加密了你的boot drive，在破解时请务必连接一个USB键盘来输入密码

  内置X220键盘的EFI驱动程序目前还不可用

• Keep your installation USB on hand. After installing macOS system updates it is sometimes necessary to boot the system with the USB and re-install kexts to get everything working properly again.

• 保留你的USB安装盘，在macOS更新时有时需要用U盘破解系统然后重新安装补丁来确保系统所有内容正常工作

• Use Clover Configurator if you need to mount the EFI partition

• 如果要安装EFI分区请使用Clover Configurator

• Using Clover Configurator to edit the default config.plist is not recommended. This program will automatically and without warning makes changes to the default settings in the <key>ACPI</key> section that will prevent the system from booting. If edits are needed, open config.plist with TextEdit and follow the format explained here.

• 使用Clover引导程序来编辑默认配置，不推荐plist

  这个流程不会提示，自动改变<key>ACPI</key>的默认设置从而阻止系统破解

  如果需要编辑配置的话，用文本编辑器打开config.plist按照以下文档改写

• If a kernel panic occurs, boot from the installation USB, select the installation drive, hit the space bar and select Boot Mac OS X in safe mode to successfully boot and make necessary changes.

• 发生“内核死机”的情况时，启动USB安装盘，选择installation drive，空格然后选择Boot Mac OS X in safe mode 来来成功启动并修改设置

• USB adapters for wireless mice or keyboards may trigger a restart when attempting to shut down. The only known solution is to remove the USB adapter before shutting down. Updating to High Sierra 10.13.6 may also resolve this issue.

• 无线鼠标或键盘的USB程序在关闭时可能会导致电脑重启。

  目前的解决方法是在关闭前移除这些USB程序

  更新High Sierra 10.13.6可能会解决这些问题

• Default sleep settings may cause a 20-25 second delay in sleeping and waking. To reduce this delay the hibernatemode setting can be changed to mode 0 by entering the following command in Applications > Utilities > Terminal:

• 默认睡眠设置可能造成在电脑睡眠/唤醒时有20-25秒的延迟

  在Applications > Utilities > Terminal中输入以下指令将睡眠模式改为mode 0来减少延迟

sudo pmset -a hibernatemode 0

• If you are encountering a black screen when waking from sleep, add darkwake=8 to the Arguments section of the Clover config.plist. Edits to the Clover config.plist can be made using the TextEdit application and following the format explained here.

• 如果电脑从睡眠模式唤醒时出现黑屏，在Clover config.plist的Arguments section中把darkwake增加到8 (darkwake=8)

  使用文本编辑器并按以下链接中的提示编辑Clover config.plist

• If System Information indicates no TRIM Support for your SSD, update your drive with the latest firmware and then enable TRIM by entering the following command in Applications > Utilities > Terminal:

• 如果系统信息显示没有对SSD的微调支持，请使用最新固件更新驱动器，然后通过输入以下命令启用微调

sudo trimforce enable

  触摸板和轨迹跟踪补丁

  ThinkPad T420 指南

  技术支持 Henry López del Pino.

• Turn off the touchpad with the <PrtSc> key if you will only be using the TrackPoint – this will prevent an issue with unintentional double-clicks with the TrackPoint buttons.

• 点击<PrtSc>按钮关闭触摸板，这时只能使用红点，它能防止意外双击跟踪点按钮时出现问题。

• Touchpad supports three-finger swipe right and left (forward and back) in Finder, Safari and other browsers as well as three-finger swipe up for Mission Control and three-finger swipe down for App Exposé.

• 触摸板支持三指左右滑动(来后退/前进)Finder, Safari和其他浏览器页面，三指滑动控制，三指切换app

• For X220 Tablet models, pen input should already work, however pressure sensitivity does not register correctly. For touch input, install ControllerMate and use one of the following ControllerMate scripts:

• 对x220T来说只能输入模式下手写笔可以使用，但是按压触感并不理想。 如果需要手写输入的话请安装https://www.orderedbytes.com/controllermate/并使用以下脚本之一

  • TouchSierra written by jakibaki. Jakibaki’s script also adds some gestures including swipe from top to get Mission Control, swipe from bottom for Launchpad and swipe from left/right to switch workspaces.
  • NewTouchSierra written by Jpeezzy. Jpeezzy’s script enables additional touch input and supports click and drag functionality.

Some users have reported random freezes where the system continues to run but the user interface becomes unresponsive. This problem occurs on many different platforms under High Sierra and is not specific to the X220. Only some X220 units are affected and we have not been able to reproduce the problem on our test units. We believe the problem may have something to do with the graphics framework and shared system memory. Here are a few things to try if you encounter this problem:

部分用户反映系统还在运行，但由于用户界面无操作而发生的锁屏问题

这个问题不是X220特有的，许多其他设备都有出现。

由于X220没有普遍出现这个问题，所以无法测试问题重现。

网站认为这个问题可能和“graphics framework and shared system memory”有关

If you have two RAM modules installed, try removing one and see if the problem still occurs. It may be that just one module that is the source of the trouble.
If you have less than 8GB of RAM, adding additional RAM may help
Try adjusting hardware acceleration settings, if possible, for applications that are running when the freezes occur (such as Chrome)

如果你安装了两个RAM内存条，请尝试卸载到其中一个再查看是否还有问题

很有可能你的其中一个内存条有问题

如果你的内存小于8G，尝试增加内存会有帮助

尝试调整硬件加速设置
