Message screen sharing is an amazing feature on Mac released first with OS X Yosemite. By setting up screen sharing on MacBook Pro or Air, you can remotely help your friend in fixing a problem occurring on his/her iPhone, iPad, or Mac. Apart from this, there can be some other uses of Mac screen sharing feature. For example, when you turn on screen sharing on Mac, you can watch videos, movies, or other contents seen by other Mac users, who may be sitting a thousand miles away. If you are not keen to share your entertainment stuff, you can do some serious tasks like sharing your presentation or share your knowledge with other users by starting screen sharing on Mac. I find this pretty interesting and helpful, and therefore, I like to share with you: how you can share screen with another Mac user in macOS high Sierra.

Like sharing your own screen, you can also view the screen of other Mac users. It’s a two-way process and this is the beauty of this screen sharing feature on Mac. Messages app plays a pivotal role here as everything is done from that app. Note that you need to use QuickTime player when you want to help with issues on iPhones or iPads. Now, read this complete guide and get to know how you can access another Mac user screen remotely.
