当您在线教学时，屏幕共享也是必不可少的，无论是您自己的在线课程(your own online course)还是教您的祖父母技术(teaching your grandparents tech)。最后，如果您选择玩不提供多人模式(multiplayer mode)的游戏，您可能希望与某人共享屏幕。

如何在 FaceTime 上共享您的屏幕(How To Share Your Screen On FaceTime)
对于Mac用户来说，FaceTime是视频通话的首选应用。虽然它可能不是目前最好的视频会议应用程序(the best video conferencing app)，但Apple用户仍然选择FaceTime而不是其他工具。它易于使用，质量上乘，而且您的联系人始终只需点击几下即可。
但是，一旦您开始使用FaceTime不仅仅是与朋友快速通话，您可能希望从中获得更多。例如，当您安排小组会议(arrange a group meeting)并需要在FaceTime上与所有人共享您的屏幕时，您会惊讶地发现没有明显的屏幕共享选项。
使用网络摄像头在 FaceTime 上共享您的屏幕(Use The Webcam To Share Your Screen on FaceTime)
如果您使用的是物理网络摄像头，则可以将其设置为面向您的计算机屏幕而不是您的脸。
这样，您的联系人将可以看到您的屏幕，但功能非常有限——更不用说此类视频会话的质量了。因此，如果您需要在FaceTime上正确共享您的屏幕，以便您的联系人在线看到您的操作并在需要时接管，请选择以下方法。
使用消息共享您的屏幕(Use Messages To Share Your Screen)
您可以通过Mac上预装的 Messages 应用程序在(the Messages app)FaceTime上共享您的屏幕。无需下载任何内容或创建任何新帐户。只需按照以下步骤操作：
- 打开信息应用程序并使用您的(Messages)Apple ID帐户 登录。
- 找到与您要与之共享屏幕的用户的聊天。或者，与他们开始新的聊天。
- 在聊天的右上角，找到详细信息(Details)按钮并单击它。
- 点击双屏(double screen)图标。
- 现在您可以选择邀请共享我的屏幕( Invite to Share My Screen)和请求共享屏幕(Ask to Share Screen)。
您还可以在聊天顶部找到屏幕共享选项。单击(Click)收件人姓名，然后从下拉菜单中选择共享您的屏幕。
另一种方法是通过应用程序的功能区菜单。在屏幕顶部，从菜单中选择好友。(Buddies)在那里，您会找到相同的“邀请共享我的屏幕”(Invite to Share My Screen)和“请求共享屏幕”(Ask to Share Screen)选项可供选择。
- 当您单击其中一个选项时，其他人将在他们的屏幕上弹出一个请求。他们可以选择接受(Accept)或拒绝(Decline)，然后您可以继续视频通话。

如果有人想访问您的 Mac：与用户共享您的屏幕，在菜单中找到双屏(double screen)图标并单击它。

要撤销控制，请再次单击双屏(double-screen)图标并禁用该功能。

It’s easy to share the screen on FaceTime on a Mac. There are multiple ways to do it. Here we will cover some of the easiest options. Also, check out our short YouTube video from our sister site, Online Tech Tips.
How To Share Your Screen On FaceTime
For a Mac user, FaceTime is the go-to app when it comes to video calls. While it might not be the best video conferencing app out there, Apple users still choose FaceTime over other tools. It’s easy to use, it provides great quality, and your contacts are always just a few clicks away.
However, once you start using FaceTime for more than just a quick call with a friend, you might want to get more out of it. For example, when you arrange a group meeting and need to share your screen on FaceTime with everyone, you’ll be surprised to find there is no obvious screen sharing option.
Use The Webcam To Share Your Screen on FaceTime
If you’re using a physical webcam, you can set it up facing your computer screen instead of your face.
That way, your contacts will get to see your screen but with very limited functionality – not to mention the quality of such a video session. So if you need to properly share your screen on FaceTime so that your contacts see your actions online and can take over when needed, choose the following method instead.
Use Messages To Share Your Screen
You can share your screen on FaceTime via the Messages app that also comes pre-installed on Mac. There’s no need to download anything or create any new accounts. Just follow these steps:
- Open the Messages app and sign in with your Apple ID account.
- Find the chat with the user that you want to share your screen with. Alternatively, start a new chat with them.
- In the upper right corner of the chat, find the Details button and click on it.
- Tap on the double screen icon.
- Now you can choose from Invite to Share My Screen and Ask to Share Screen.
You can also find the screen-sharing options right on top of the chat. Click on the recipient name and choose to share your screen from the drop-down menu.
Another way to do it is through the app’s ribbon menu. At the top of the screen, choose Buddies from the menu. There, you will find the same Invite to Share My Screen and Ask to Share Screen options to choose from.
- When you click on one of the options, the other person will get a request pop up on their screen. They can choose to Accept or Decline, then you can continue your video call.
Use Messages To Access Their Mac
Sometimes simply showing your screen to the other user isn’t enough. If you want to make it more interactive, you can invite them to control your computer or ask to access theirs.
If you want to access someone’s Mac, wait until they’re sharing their screen on FaceTime with you, find the mouse icon in the upper left corner of the screen and click on it.
If someone wants to access your Mac: share your screen with the user, find the double screen icon in the menu and click on it.
Before you let someone access your computer, make sure it’s someone you trust. Remember that they will get full control over your computer and the ability to go through your files, including your sensitive personal data.
To revoke control, click on the double-screen icon again and disable that function.
How to Share Your Screen Offline
Even when there’s no internet access, you can use the built-in Screen Sharing app to connect to another Mac remotely.
To launch Screen Sharing, open the Spotlight search and type in screen sharing.
The app will ask you for a hostname or an Apple ID of the user you want to connect to. Using the Apple ID you can connect to their computer directly. Just type their Apple ID in and click Enter. Leave the rest for your Mac.
The only downside with this method is that there’s no space for messaging or discussing the issues during the screen-sharing session. However, you can use Facetime or Messages for that.
Share Your Screen On FaceTime With Anyone
Your Mac makes it rather easy to share your screen with other users and even with yourself. There are many ways to access your computer remotely if you ever need that.
If you find that the built-in tools you have on your Mac aren’t enough, you can always turn to third-party tools to remote connect to any computer.
