Give your family the gift of remote tech help using your Mac and iMessagesYou can use Message screen sharing on your Mac to help fix problems on other Macs, as well as iOS devices. Here's how.
Messages on the Mac works a lot likes its sibling app for iPhone and iPad, letting you keep in touch with friends and family through standard text messages or iMessage. But the Mac app has something extra to it as well: you can share your screen or view the screen of other Mac users.
You can invite someone to share your screen, or request or be invited to share the screen of another person's Mac, and it's all done through Messages. This is a great way to help troubleshoot problems on a remote Mac, and with a little help from QuickTime, you can even help with issues on an iPhone or iPad, too.
