How to share screen on Mac

If you want to know how to share your screen on Mac then the good news is, Macs already have a built-in screen sharing tool. Since OS X 10.4, Macs have a tool called Screen Sharing located in the CoreServices folder. As with many features built into OS X, it makes it simple to screen share on a Mac. Screen Sharing is extremely stable and auto-remembers important information such as your recent servers and passwords. Just follow these instructions to start sharing your screen:

Before you start, you need to make sure that Screen Sharing is enabled on the target Mac i.e. the Mac screen that you want to appear on your desktop. To do this, go to System Preferences and click on Sharing under Internet & Wireless Preferences.

The connection can be a bit slow compared to using a third-party screen sharing client but the image quality is very good. And if you are using Lion or above, you can switch to full screen mode using the expansion arrow.

Note that this method does not work for sharing an iPad screen. To do that, you’ll need to install a third party VNC client such as Jolllys Fast VNC or Chicken of the VNC.
