MACOS MOJAVE 10.14 ON THE THINKPAD X220

關(guān)于MACOS MOJAVE 10.14安裝版

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

隨著macOS Mojave 10.14版發(fā)布，Apple停止對ThinkPad X220的'系統(tǒng)電腦型號'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.

由于蘋果在圖形處理技術(shù)上棄用OpenGL和OpenCL而轉(zhuǎn)向Metal,X220的英特爾HD3000處理器和MacBook Pro 及 MacBook Air之前的版本都與Metal不兼容

蘋果棄用 OpenCL 和 OpenGL 告喊，OpenCL 或遭全面淘汰
在 MacOS 10.14 的更新文檔中，蘋果表示使用 OpenGL 和 OpenCL 構(gòu)建的應(yīng)用可以繼續(xù)在 macOS 10.14 中運(yùn)行派昧，但這些遺留技術(shù)在 macOS 10.14 中不推薦使用∏現(xiàn)在使用 OpenGL 的游戲和應(yīng)用應(yīng)轉(zhuǎn)向 Metal 。 同樣蒂萎，使用 OpenCL 進(jìn)行計(jì)算任務(wù)的應(yīng)用也應(yīng)該采用 Metal 和 Metal Performance Shaders 秆吵。

Intel HD Graphics 3000是用在英特爾第二代酷睿系列處理器上的集成顯卡。
Intel HD Graphics 3000是用在第二代酷睿處理器上的集成顯卡五慈，這一代集成顯卡性能普遍較低纳寂，只能完成日常工作，對于3D游戲的支持比較欠缺泻拦。
核心顯卡仍然和集成顯卡一樣需要耗費(fèi)內(nèi)存資源毙芜，所以用戶使用核心顯卡時(shí)需要2GB或以上的內(nèi)存，由于HD3000核心顯卡在與CPU協(xié)同工作時(shí)仍存在不兼容現(xiàn)象争拐，使得其性能不能發(fā)揮到極致腋粥，所以市場上仍然有Core i3-2310M或2330M處理器屏蔽核心顯卡而用GeForce GT520或GT540的搭配，有些高端筆記本使用雙顯卡交火模式也是為了使用獨(dú)立顯卡彌補(bǔ)核心顯卡性能有限的不足架曹，但是HD3000仍然可以滿足普通用戶的需求隘冲，如觀看高清影音膜钓，一般文字處理和普通3D游戲允睹，只是在大型游戲和發(fā)燒娛樂上明顯不足创坞。

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可以通過在macOS的早期版本中打kexts補(bǔ)丁躲株，從而在X220上運(yùn)行系統(tǒng)邑茄。由于Mojave缺少原生圖形支持漩怎，目前網(wǎng)站停止X220安裝MacOS方法的更新糊秆。

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.

建議事項(xiàng)

• 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.

• 如果電腦從睡眠恢復(fù)時(shí)發(fā)生系統(tǒng)奔潰姿鸿，請嘗試以下操作

  1>確保 Preferences > Bluetooth > Advanced… 中的"Allow Bluetooth devices to wake" 已經(jīng)勾選谆吴，并且確保你的x220在睡眠前至少已有一個藍(lán)牙設(shè)備連接

  2>禁止Security > I/O Port Access > Bluetooth 下的BIOS中的藍(lán)牙設(shè)備

  或者

  3>使用t420中tluck創(chuàng)建的解決方案

• 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

• 如果電腦從睡眠中恢復(fù)后藍(lán)牙是不可用的，關(guān)掉電腦左邊的無線按鈕然后再打開

• 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苛预，在破解時(shí)請務(wù)必連接一個USB鍵盤來輸入密碼

  內(nèi)置X220鍵盤的EFI驅(qū)動程序目前還不可用

• 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安裝盤句狼，在macOS更新時(shí)有時(shí)需要用U盤破解系統(tǒng)然后重新安裝補(bǔ)丁來確保系統(tǒng)所有內(nèi)容正常工作

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

• 如果要安裝EFI分區(qū)請使用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引導(dǎo)程序來編輯默認(rèn)配置，不推薦plist

  這個流程不會提示热某，自動改變<key>ACPI</key>的默認(rèn)設(shè)置從而阻止系統(tǒng)破解

  如果需要編輯配置的話腻菇，用文本編輯器打開config.plist按照以下文檔改寫

• 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.

• 發(fā)生“內(nèi)核死機(jī)”的情況時(shí)，啟動USB安裝盤昔馋，選擇installation drive筹吐，空格然后選擇Boot Mac OS X in safe mode 來來成功啟動并修改設(shè)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.

• 無線鼠標(biāo)或鍵盤的USB程序在關(guān)閉時(shí)可能會導(dǎo)致電腦重啟。

  目前的解決方法是在關(guān)閉前移除這些USB程序

  更新High Sierra 10.13.6可能會解決這些問題

• 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:

• 默認(rèn)睡眠設(shè)置可能造成在電腦睡眠/喚醒時(shí)有20-25秒的延遲

  在Applications > Utilities > Terminal中輸入以下指令將睡眠模式改為mode 0來減少延遲

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.

• 如果電腦從睡眠模式喚醒時(shí)出現(xiàn)黑屏秘遏，在Clover config.plist的Arguments section中把darkwake增加到8 (darkwake=8)

  使用文本編輯器并按以下鏈接中的提示編輯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:

• 如果系統(tǒng)信息顯示沒有對SSD的微調(diào)支持丘薛，請使用最新固件更新驅(qū)動器，然后通過輸入以下命令啟用微調(diào)

sudo trimforce enable

Touchpad, TrackPoint and Tablet Input

觸摸板邦危，聯(lián)想紅點(diǎn)按鈕洋侨，智能輸入

• Touchpad and TrackPoint use a version of RehabMan’s VoodooPS2Controller.kext modified by tluck for the ThinkPad T420 in the guide here and further modified for gesture support by Henry López del Pino.

  觸摸板和軌跡跟蹤補(bǔ)丁

  ThinkPad T420 指南

  技術(shù)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.

• 點(diǎn)擊<PrtSc>按鈕關(guān)閉觸摸板，這時(shí)只能使用紅點(diǎn)倦蚪，它能防止意外雙擊跟蹤點(diǎn)按鈕時(shí)出現(xiàn)問題希坚。

• 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.

• 觸摸板支持三指左右滑動(來后退/前進(jìn))Finder, Safari和其他瀏覽器頁面，三指滑動控制陵且，三指切換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:

• 對x220T來說只能輸入模式下手寫筆可以使用裁僧，但是按壓觸感并不理想。 如果需要手寫輸入的話請安裝https://www.orderedbytes.com/controllermate/并使用以下腳本之一

X220T的話觸摸屏的壓力敏感度不準(zhǔn)確

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:

部分用戶反映系統(tǒng)還在運(yùn)行，但由于用戶界面無操作而發(fā)生的鎖屏問題

這個問題不是X220特有的踩麦，許多其他設(shè)備都有出現(xiàn)枚赡。

由于X220沒有普遍出現(xiàn)這個問題，所以無法測試問題重現(xiàn)谓谦。

網(wǎng)站認(rèn)為這個問題可能和“graphics framework and shared system memory”有關(guān)

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)

如果你安裝了兩個RAM內(nèi)存條贫橙，請嘗試卸載到其中一個再查看是否還有問題

很有可能你的其中一個內(nèi)存條有問題
