如何使用RealVNC从Windows复制和粘贴到Mac？

Please, make sure you fullfilled the checklist referenced in the documentation:

• Does the amount of text being copied and pasted exceed 256kB? If so, the entire paste operation will fail, and the last text copied to the Clipboard will be pasted instead.
• Has VNC Server been configured to disable copy and paste? If you have access, check global permissions on the VNC Server Options > Users & Permissions page.
• Has VNC Server been configured to prevent you copying and pasting? If you have access, check permissions for the user you are registered as on the VNC Server Options > Users & Permissions page.

If all the settings are correct, all I can say is that it should work out of the box without further configuration, so either you have something not properly installed or you have some short of firewall or sandbox protecting one of your clipboards, preventing the entire operation from succeding. I'm no mac or Windows expert, but Windows firewall SHOULD NOT be doing this (although, never tested it under W10).

I've little experience with RealVNC (never cross-platform), but with pure VNC it was straight-forward between linux and windows, so I see no reason for RealVNC missing the feature, specially considering they explicitly state it in their docs.

All this said, the most reasonable thing is to suppose you have a configuration issue or some unwanted interaction with other software. I suggest you the following, in order of difficulty and probability of success:

1. Try executing VNC as admin in Windows side (I don't know if you can do it in MACs GUI, but I supose you can too, so try there too).
2. Review the settings. Check if copy-pasting is disabled, either at user-level or system-level, in both sides.
3. Do you have any software (not only antivirus) that may be interfering? If so, check the documentation in order to allow VNC to do its job.
4. If it doesn't work, do a PROPER uninstall in both sides. Track the installation manually or use some deletion software, there're plenty of them.
5. Reboot.
6. Install latests versions. Try to have the same version in both computers. Use a lowr-than-the-last in one computer if needed.
7. Reboot.

As a rule of thumb, network programs usually give less problems if used with the same version, however, the developer will probably state the compatibility range somewhere.

Edit to answer your modified question:

When we call about "clients" and "servers", to make things simple, you can say that the client is the one which MAKES A CALL (in this case connect to a remote machine) and the server is who RECIEVES such calls (in this case, sharing a desktop). To sum up, a VNC server is a program which waits for VNC clients to make a request and then shares it's screen with them.

VNC client is the windows software you use to connect, while VNC server seems to be a built-in mac software. In the past you could use the same RealVNC executable to act as a server and a client, but now they made a more commercial-driven software, VNC Connect, which is what you need to install in your MAC in order to share your desktop and copy paste with RealVNC. I'm not sure if this is free, though, but I think it isnt, check it out anyway.

Steps:

1. 使用您粘贴的窗口在Mac中禁用屏幕共享。
2. 下载VNC连接在你的Mac这里。
3. 配置它以进行桌面共享。这一定很容易，但是我不习惯使用该软件。
4. 使用您的VNC客户端进行连接。Windows上的设置很可能会完全相同

在此之前，您还可以尝试Windows的不同VNC客户端（例如UltraVNC），也许您很幸运，问题在于RealVNC无法理解您的Mac如何尝试发送剪贴板信息，但是我认为这是一个问题。 Mac的内置vnc服务器。
