在升级macOS Sonoma 之前，我们需要对EFI 进行调整，以确保操作系统可以顺利安装和运行。

第一点心得是备份。

在进行任何操作之前，备份EFI 是非常重要的。

通过备份EFI，无论在调整过程中遇到何种问题，我们都可以恢复到之前的状态，并避免可能出现的数据丢失。

备份EFI 的方法可以通过命令行工具dd 或者使用第三方工具来完成。

在备份时，可以将EFI 目录中的文件复制到另一个位置，或者创建一个完整的镜像文件进行存储。

第二点心得是使用适当的工具。

在调整EFI 时，选择合适的工具非常重要。

常用的工具包括Clover、OpenCore 等。

这些工具可以协助我们设置EFI 启动选项，以满足系统安装和运行的要求。

在选择工具时，需要考虑到自己的硬件配置和操作系统的版本，并确保选用的工具与之兼容。

第三点心得是熟悉EFI 配置文件。

EFI 配置文件是用来设置EFI 启动选项的重要组成部分。

通过编辑EFI 配置文件，我们可以设置系统的引导选项、硬件参数等。

在编辑配置文件时，需要关注相应的语法和参数设置，以确保设置的正确性和合理性。

通常，EFI 配置文件可以使用文本编辑器进行编辑，例如使用vi 或者nano 等命令行工具。

此外，也可以使用一些第三方工具来简化配置文件的编辑。

uniks常用命令-回复Uniks常用命令：探索Unix操作系统中的精华Unix操作系统是一种非常强大和广泛使用的操作系统，被广泛应用于网络服务器、超级计算机和大型企业系统。

Uniks是Unix系统的一个变种，具有其特定的命令和特性。

在本文中，我们将重点介绍Uniks常用命令，并逐步详细解释它们的功能和用法，帮助读者更好地了解和利用这些强大而实用的工具。

首先，让我们从最基础的命令开始，即文件和目录操作命令。

1. ls：该命令用于列出当前目录中的文件和子目录。

通过ls命令，您可以查看文件和目录的名称、类型、权限等信息。

例如，输入ls命令，系统将返回当前目录中的所有文件和目录名。

2. cd：该命令用于更改当前工作目录。

通过cd命令，您可以进入到其他目录中，或返回上级目录。

例如，输入cd /home将切换到名为“home”的目录。

3. pwd：该命令用于显示当前工作目录的路径。

通过pwd命令，您可以确认当前所处的目录位置。

4. mkdir：该命令用于创建新的目录。

通过mkdir命令，您可以在当前目录中创建一个新的子目录。

例如，输入mkdir mydir将创建一个名为“mydir”的目录。

5. rmdir：该命令用于删除空目录。

通过rmdir命令，您可以删除空的子目录。

例如，输入rmdir mydir将删除名为“mydir”的目录。

接下来，让我们继续学习文件操作命令。

6. touch：该命令用于创建空文件或更改文件的时间戳。

通过touch 命令，您可以创建一个新的空文件，或者更改现有文件的访问和修改时间。

例如，输入touch myfile将创建一个名为“myfile”的空文件。

7. cp：该命令用于复制文件或目录。

通过cp命令，您可以将文件或目录从一个位置复制到另一个位置。

例如，输入cp myfile mydir将文件“myfile”复制到目录“mydir”中。

8. mv：该命令用于移动文件或目录，或者重命名文件或目录。

1,格盘，先分出2个盘，分别为mac boot 和mac osboot最少10g，macos最少40g2,用“安装助手_0.3”把mac os 写入boot盘，做为硬盘安装,(以管理员身份运行)注意：只留下一个写入。

如果这步骤写入不了，到磁盘管理里面，删除该磁盘，然后重启给这个磁盘分配一个盘符，但是不要格式化它，就可以了。

3,把安装盘里面的E:\System\Library\Extensions下的N开头的5个剪切到另外一个目录. 4,把Extra.rar解压到boot盘(e盘)根目录下5,安装变色龙软件Chameleon Install 2012用来设置启动项6,设置硬盘通道并检查硬盘通道驱动模式:6.1,BIOS方式启用AHCI硬盘模式,先将Windows7下面的硬盘通道驱动改为AHCI标准串口模式。

6.2,输入regedit命令在注册表中查找→→→→→7,重启机器后，进入变色龙，然后选择boot那个盘，在键盘上输入：-v npci=0x20008,等待mac界面，选择磁盘管理工具，选择macos盘，抹掉，然后下一步9,安装完了后，系统重启前，插入win7 安装盘，来修复启动项10,重启系统进入win7，此时看不到mac os的两个盘11,安装MacDrive_8&9_x64/MacDrive8.x64.en-US.msi(该版本支持64位win7)12,安装Ext2Fsd-0.51_exe,然后挂载moc os盘挂载完后，重新到资源管理器里面，就能看到2个硬盘了。

13,把Extra拷贝到macos的根目录下，把Kext_Utility.app.v2.5.1.zip拷贝到macos里面的某个目录下，如：F:\Users\cjd\Desktop，14,把F:\System\Library\Extensions里面的N开头的5个删除，然后把D:\黑苹果安装\NV拷贝到macos 的F:\System\Library\Extensions15,重启系统，进入变色龙，进入macos16,解压Kext_Utility.app.v2.5.1.zip然后，运行Kext_Utility.app.v2.5.1来修复显卡，修复后重启进入macos，就能看到酷炫的moc os了。

此前曾多次尝试用硬盘安装助手和变色龙来安装Mac OS X 但均未成功。

镜像可以写入硬盘，电脑的启动选项里也出现了Mac OS X 和变色龙的选项，可都不能进入进行安装。

就其原因有二：第一我的PC从CUP到主板芯片组再到显卡都是AMD的，兼容程度上不如INTEL的；第二因为是单位给配的电脑，都有增霸卡，启动系统是无法绕过此硬件。

终于，改变思路，用虚拟机VirtualBox安装。

我用的版本是3.2.4的，最新的版本是3.2.10。

其实界面和操作都差不多，在这里就不多说什么了，论坛里和网上都有很细致的教程。

只有一点要提的，建立虚拟介质时，操作系统选Mac OS ，下一个选项当然就选Mac OS server。

1.打开虚拟机，再打开你建立好的虚拟硬盘，会出现以下画面按任意键，开始安装。

2.选择简体中文3.选择实用工具里的磁盘工具，进行摸盘，这是必须的。

4.摸盘完成后就真正进入了安装阶段5.此时一定不能直接点安装，要点下图最左边的自定。

6.此时会出现各种驱动的选项，第一项已经默认选择了，不要动，剩下的要根据你电脑的具体配置进行选择，这一步至关重要，如果做不好会导致你安装的mac os 不能运行。

后面会有详细的配置驱动选择说明。

7.等待安装，大约20分钟左右8.安装成功，重启。

9.此时点Show All ,再选China,不说相信大家都知道吧。

10.这里的ID可以不填，如下图12.下图可以随意填写。

13.下图的用户名和密码即PASSWOED请记住，以后安装软件时需要输入的。

14 好了进入只属于你的MAC OS世界吧！下面是我安装好的MAC OS X 截图iDeneb 10.5.6自定义驱动详细中文说明警告!不要将这个版本覆盖安装到已存在的Mac OS X上，这可能导致安装失败。

不要选择两个或更多相同种类的驱动，比如说，同时安装两个声卡或SMBIOS的驱动，很多情况下会导致安装失败。

默认安装9.6原版内核。

升级macos sonoma 时efi 调整的一点心得-回复升级MacOS Sonoma 时EFI 调整的一点心得近期，我升级了我的Mac 版本到最新的MacOS Sonoma。

在这个过程中，我遇到了一些问题，并对EFI 进行了一些调整。

在这篇文章中，我将会分享一下我的心得和经验。

首先，让我们来理解一下EFI 是什么。

EFI（Extensible Firmware Interface）是一种替代传统BIOS 的新一代计算机启动标准。

它负责引导和初始化计算机系统，同时还提供了一个通用接口，用于操作系统和硬件之间的沟通。

在Mac 上，EFI 提供了一些配置选项，可以让用户根据自己的需求来调整系统设置。

在升级MacOS Sonoma 之前，我首先备份了我的EFI 文件夹。

这个文件夹包含了系统引导所需要的配置文件和驱动程序。

由于系统升级可能会导致一些配置文件和驱动程序的更改，所以备份是非常重要的，以防止出现不可预料的问题。

在升级完成后，我发现一些旧的EFI 配置文件和驱动程序无法与新的系统兼容。

这可能是由于系统结构的改变或者驱动程序的不完整性导致的。

为了解决这个问题，我需要升级我的EFI 文件夹。

首先，我访问了相关的论坛和社区，查找了一些新的EFI 配置文件和驱动程序。

在这些社区中，许多用户分享了他们的调整和解决方案。

我找到了与我的硬件相匹配的EFI 配置文件和驱动程序，并将它们下载到了我的电脑上。

然后，我用新的EFI 文件夹替换了旧的文件夹。

在这个过程中，我注意到了一些注意事项。

首先，确保备份旧的EFI 文件夹，以防出现问题时可以恢复到之前的版本。

其次，只替换需要替换的文件。

有时候，只需要替换部分配置文件或者驱动程序就可以解决问题，而不需要替换整个文件夹。

最后，确保新的EFI 文件夹与你的硬件兼容。

如果你使用了不同的硬件配置，可能需要下载不同的EFI 文件夹。

完成替换后，我重新启动了我的电脑。

我注意到系统引导速度变得更快了，并且一些驱动程序的稳定性也有所改善。

In such cases, you may want to increase the buffer size.PersonalizationUse the Personalization section to enter information about yourhead dimensions: your head circumference and the distancebetween your ears (“Inter-Aural Arc”). Entering these measurementswill result in optimal Nx experience.Default settings are based on average adult head size, but since headsizes vary between individuals, it’s advised to adjust the settings toyour personal dimensions.Measurement Ranges∙Circumference: 35–75 cm (14.8–29.5 inches), Default: 55 cm / 21.6 in∙Inter-Aural Arc: 15–40 cm (6.9–15.75 inches), Default: 25 cm / 9.8 inHow to Measure Your Head:Use a measuring tape to measure the full circumference of your head, over theback of the head, just above the ears, and over the eyebrows. Enter thismeasurement in the Circumference box (in either centimeters or inches).Next, measure the semi-circumference from ear to ear (from one ear canalentrance to the other, around the back of the head. Enter this measurement inthe Inter-Aural Arc box.3. Head TrackingHead tracking greatly enhances the 3D audio experience. By tracking your head movements and adjusting the audio to the direction and orientation of your head, Nx reconstructs more realistically the three-dimensional audio experience of sounds coming at you from external sources in the real world.Head tracking can be done in two ways: using your computer’s camera, or using the Nx Head T racker.3.1 Tips for Optimal Performance When Using the CameraIf you are using the Nx Head Tracker device, you should have no issues with head tracking performance.If you are using the computer’s camera for head tracking, the head tracking rate may be come low under certain conditions. If the head tracking rate is too low to maintain proper orientation, the head model on the main Nx window will be displayed in gray. To increase the head tracking rate, try these solutions:∙Improve lighting conditions.∙Click on the Camera Preview button.∙Make sure that your face is well-lit and not shadowed. You may need to tilt the camera up a bit to increase light exposure to the face.If the Nx application regularly loses track of your head:∙Click on the Camera Preview button.∙Position the camera closer and straight in front of you.∙Remove sunglasses, hat, or anything covering your face.∙Improve lighting conditions.∙Don’t go beyond +/-30 degrees off the center axis.∙Make sure you’re within 1.2 meters/ four (4) feet from the camera.3.2 Using the Nx Head TrackerAttachingAfter you insert a standard AAA battery into the Nx Head Tracker, position thedevice at the top-center of the headphone arc, with the Nx logo facing forwards(battery in the back). The Nx Head Tracker will not track your head movementsproperly if you place it off-center or facing backwards.Wrap the strap around the headphone arc and attach it to the hook on the otherside. The strap can be disconnected at both ends for replacement: any standardrubber band can be used if needed.Button FunctionsA short press (under two seconds) in any state will place the unit in advertising mode.

With the Nx Head Tracker you can track your headmovements while you are moving around, for example using a mobile device.∙ A webcam can track your head movements in ±30 degrees only. The Nx Head Tracker can track them in full 360 degrees.∙With a webcam, only one user can use Nx software at a time; with the Nx Head Tracker, several users (each with his or her own Nx Head Tracker device) can experience Nx simultaneously on the sameaudio source.∙CPU consumption is lower when using the Nx Head Tracker when compared to using the webcam.∙Battery consumption is lighter when using the Nx Head Tracker.Here’s a more detailed compa rison:Nx Head Tracker Webcam For Use with Both stationary and mobile devices Stationary devices only (desktop or laptop) CPU Consumption Low HighTracking Angle 360° (full sphere) 60° (+/-30°)Tracking Speed (RefreshRate)50 frames per second (fps) Up to 30 fps in good lighting conditionsLighting Does not require lighting Sensitive to lighting conditionsDistance from YourDevice Approx. 10-20 feet, depending onBluetooth range3-6 feet, depending on lens field-of-view angleTracking Orientation andPosition 3 degrees of freedom: orientation only(yaw/pitch/roll)6 degrees of freedom: orientation(yaw/pitch/roll) + position (XYZ)。
