I am trying to copy contents from my host machine to a guest machine, but for copying I need to install the Guest additions disk.

我正在尝试将内容从主机复制到来宾计算机，但要进行复制，我需要安装来宾添加磁盘。

Or there is there another way to access host machine content on the guest machine or vice-versa?

或者，是否有其他方法可以访问来宾计算机上的主机内容，反之亦然？

Guest Additions are available for MacOS starting with VirtualBox 6.0.

从VirtualBox 6.0开始，MacOS可以使用来宾添加功能。

Installing:

安装：

1. Boot & login into your guest macOS.


2. In VirtualBox UI, use menu Devices | Insert Guest Additions CD image...


3. CD will appear on your macOS desktop, open it.


4. Run VBoxDarwinAdditions.pkg.


5. Go through installer, it's mostly about clicking Next.


6. At some step, macOS will be asking about permissions for Oracle. Click the button to go to System Preferences and allow it.


7. If you forgot/misclicked in step 6, go to macOS System Preferences | Security & Privacy | General. In the bottom, there will be a question to allow permissions for Oracle. Allow it.

Troubleshooting

故障排除

1. macOS 10.15 introduced new code signing requirements; Guest additions installation will fail. However, if you reboot and apply step 7 from list above, shared clipboard will still work.


2. VirtualBox < 6.0.12 has a bug where Guest Additions service doesn't start. Use newer VirtualBox.

1. In the guest Mac, open the Terminal and go for a reboot on the Recovery partition

sudo nvram "recovery-boot-mode=unused"
sudo reboot

2. Now you're in Recovery mode, enter the Terminal and do:

csrutil disable
spctl kext-consent add VB5E2TV963
nvram -d recovery-boot-mode
reboot

3. Back in "normal" mode, open the Terminal, and do:

sudo mount -uw /
sudo chown :admin /System/Library/Extensions/
sudo chmod 775 /System/Library/Extensions/

4. Run the Guest Additions installer and go through the end
   (in principle, it goes through successfully)

   
   



5. Now in the terminal, do:

   
   

sudo chown :wheel /System/Library/Extensions/
sudo chmod 755 /System/Library/Extensions/
sudo nvram "recovery-boot-mode=unused"
sudo reboot

6. Again in Recovery mode, go into the Terminal and do:

csrutil enable
nvram -d recovery-boot-mode
reboot

You should be set.

你应该准备好了。

Guest additions are not available for Mac OS X. You can get features like clipboard sync and shared folders by using VNC and SMB. Here's my answer on a similar question.

Mac OS X不支持来宾添加功能。你可以通过使用VNC和SMB获得剪贴板同步和共享文件夹等功能。以下是我对类似问题的回答。

You can use SSH and SFTP as suggested here.

您可以按照这里的建议使用SSH和SFTP。

1. In the Guest OS (Mac OS X), open System Preferences > Sharing, then activate Remote Login; note the ip address specified in the Remote Login instructions, e.g. ssh [email protected]


2. In VirtualBox, open Devices > Network > Network Settings > Advanced > Port Forwarding and specify Host IP = 127.0.0.1, Host Port 2222, Guest IP 10.0.2.15, Guest Port 22


3. On the Host OS, run the following command sftp -P 2222 [email protected]; if you prefer a graphical interface, you can use FileZilla

Replace user and 10.0.2.15 with the appropriate values relevant to your configuration.

使用与您的配置相关的相应值替换USER和10.0.2.15。

I've the same problem, and by the "trial and error" method I have the steps to install the guest additions on a MacOS guest:

我也有同样的问题，通过“试错”的方法，我得到了在MacOS来宾上安装来宾添加的步骤：

1. insert the guest additions cd


2. open the cd on file manager


3. double click on VBoxDarwinAdditions.pkg


4. the installer opens, then click contine


5. next screen to set location of installed files, only press install


6. your password can be asked a couple of time while installing, write
   it and continue


7. this is the tricky part, on my installation, macos show an message
   about the driver created by oracle won't be installed because a
   security issue, it has the option to enable it, so click on the
   button to open security screen and click on the allow button next to
   the oracle software listed at bottom of the security settings
   window, it will ask your password again. Meanwhile the pkg installer
   continued as if it has permissions and will say "install finished",
   but I don't believe it so, once I unlocked the oracle drivers
   installations I repeat the whole process from step 3, and in the
   second round all installs without asking more than the first
   password to install.

And it is done!

一切都结束了！

Above, someone gave a hint:

上图中，有人给出了一个暗示：

At some step, macOS will be asking about permissions for Oracle. Click the button to go to System Preferences and allow it.
If you forgot/misclicked in step 6, go to macOS System Preferences | Security & Privacy | General. In the bottom, there will be a question to allow permissions for Oracle. Allow it.

在某个步骤中，MacOS将询问Oracle的权限。单击按钮转到系统首选项并允许它。如果您在第6步中忘记/错误点击，请转到MacOS系统首选项|安全与隐私|常规。在底部，会出现一个问题，要求授予Oracle权限。允许它。

It took me a couple of hours but I did finally find what he was talking about - it's actually in the bottom of the Mac - click on the gear icon and you'll find it eventually.

我花了几个小时，但我终于找到了他在说什么--它实际上在Mac的底部--点击齿轮图标，你最终会找到它的。

You need to update your virtualbox sw. On new version, there is VBoxDarwinAdditions.pkg included in a additions iso image, in older versions is missing.

您需要更新您的VirtualBox软件。在新版本中，VBoxDarwinAdditions.pkg包含在添加的iso镜像中，在旧版本中缺失。

you can do it from the windows 10 terminal

你可以在Windows10终端上操作

step 1: open CMD in administrator mode

步骤1：在管理员模式下打开CMD

step 2 paste this open CMD cd "C:\Program Files\Oracle\Virtualbox"

步骤2粘贴这张打开的CMD CD“C：\Program Files\Oracle\VirtualBox”

step 3: paste this command in the open CMD, you must indicate the name you have in VirtualBox

步骤3：将此命令粘贴到打开的CMD中，您必须在VirtualBox中注明您的名称

VBoxManage setextradata "Virtual machine name" VBoxInternal2/EfiGraphicsResolution X

Example:

示例：

VBoxManage setextradata "Mac OS Sierra" VBoxInternal2/EfiGraphicsResolution 1280x720

Before you start, close VirtualBox!
After those manipulations start VB as Administrator!

在开始之前，关闭VirtualBox！在这些操作之后，以管理员身份启动VB！

---

1. Run CMD as Administrator


2. Use lines below one by one:

• cd "C:\Program Files\Oracle\Virtualbox"


• VBoxManage setextradata “macOS_Catalina” VBoxInternal2/EfiGraphicsResolution 1920x1080

Screen Resolutions: 1280x720, 1920x1080, 2048x1080, 2560x1440, 3840x2160, 1280x800, 1280x1024, 1440x900, 1600x900

Description:

描述：

• macOS_Catalina - insert your VB machine name.

  macOS_Catalina -插入您的VB计算机名称。

  
  



• 1920x1080 - put here your Screen Resolution.
