Screen Sharing Apps for Mac: Choosing One for Online Meetings

Which screen sharing app to use on a Mac for online meetings, how macOS screen capture permissions work, and practical tips for sharing safely and clearly.

Which screen sharing app should you use on a Mac?

For online meetings, the most practical screen sharing app on a Mac is usually the meeting platform your participants already use. Zoom, Microsoft Teams, Google Meet, Webex and FaceTime all let a Mac user share their screen during a call. The Screen Sharing app built into macOS is a different kind of tool. It is designed for viewing or controlling another Mac, not for presenting to a group in a meeting.

  • Zoom, Microsoft Teams and Webex: desktop apps suited to scheduled meetings with colleagues, clients or external guests. They offer options to share a whole display or a single window.
  • Google Meet: runs in a web browser, so the browser handles screen capture and shows its own picker for a screen, window or tab.
  • FaceTime with SharePlay: lets you share your screen with people on Apple devices, on macOS versions that support it.
  • Team chat tools with built-in calls, such as Slack huddles: convenient for quick internal walkthroughs without scheduling a separate meeting.
  • macOS Screen Sharing: for remote help between Macs rather than for presentations.

If someone else hosts the meeting, their platform decides for you. If you are the host, choose based on what your audience can join easily, whether you need recording, whether participants should be able to take remote control, and what your organization allows.

How screen sharing works on macOS

A meeting app captures what is on your display, encodes it as a video stream and sends it through the meeting service to other participants. macOS protects screen capture with a privacy permission. The first time an app tries to share, macOS asks you to allow it in the Privacy & Security section of System Settings. The exact name of this permission has changed between macOS releases. Some apps must be quit and reopened before a newly granted permission takes effect, and recent macOS versions may occasionally ask you to confirm the permission again.

Most apps let you share either an entire display or a single window, and browser-based meetings often add the option of sharing one tab. Sharing an entire display shows everything that appears on it, including pop-ups and notifications. Sharing a window limits the view to that app. Newer macOS versions also offer system-level video and sharing controls in the menu bar for apps that support them. On supported Macs running macOS Sonoma or later, this includes Presenter Overlay, which places your camera image over the shared content.

Computer sound is handled separately from the picture. Whether you can share system audio, such as a video clip, depends on the app and the way it captures sound on macOS. Some meeting apps provide their own audio component for this, while a browser may only share audio from a single tab. Check the audio option in the app's share dialog before you rely on it.

The general process described above is the same everywhere: capture permission, a choice of what to share, and a separate audio choice. Button names, permission labels and the availability of specific features depend on your macOS version, the app version, your plan and any administrator policies.

Sharing your screen in a meeting: practical choices

  • Grant permission in advance: start a test share before the meeting so any macOS permission prompt and app restart happen ahead of time.
  • Turn on a Focus mode such as Do Not Disturb so notifications do not appear on a shared display. Some apps can hide notifications themselves, but check this rather than assuming it.
  • Close or hide windows with private content, such as email, chat, password managers and browser tabs you do not want seen.
  • Share a single window when you are presenting one document, and the entire screen only when you need to switch between several apps.
  • If you have two displays, share one of them and keep your notes and meeting controls on the other.
  • If you plan to play a video or other sound, turn on the app's computer audio option before you start sharing.

Presenting slides: share the window or display that shows the slideshow, not the editing view. If your presentation app uses a presenter view, it is usually easiest with two displays, with the audience-facing slides on the shared display and the presenter view on the other. With one display, check in a test share which window participants actually see.

Software demos and walkthroughs: share the specific app window so that switching to other apps does not expose them. If a participant needs to click or type on your Mac, use the meeting app's remote control feature where it exists. On a Mac, allowing someone else to control your computer may require granting the app an additional Accessibility permission.

Helping someone who also uses a Mac: for one-to-one support, the built-in Screen Sharing app or FaceTime with SharePlay can be simpler than setting up a full meeting, provided both Macs meet the version requirements.

Limits and related questions

Image quality: Mac displays often have high resolutions, and sharing a large display or fast-moving content can look blurry or choppy for viewers on slower connections. Sharing a smaller window, or using an app's option optimized for video playback where available, can help.

Privacy and recordings: anything you share can be seen by everyone in the meeting, and the host or participants may be able to record it. How the service processes, stores or retains shared content and recordings depends on the provider, your plan and your organization's settings. Check the provider's own privacy documentation and your organization's policy rather than assuming.

Work Macs: on Macs managed by an organization, administrators can restrict which apps are installed or which privacy permissions can be granted. If sharing is blocked and no permission prompt appears, contact your IT team.

Is there a free screen sharing app for Mac? Several meeting platforms offer free tiers that include screen sharing, and FaceTime is included with macOS. Free plans may limit meeting length, number of participants or features, and these terms change, so check the current plan details before choosing one for regular meetings.

Why do participants see a black screen or only the desktop wallpaper? The usual cause is a missing screen capture permission, or a permission that has not taken effect because the app has not been restarted. Protected content, such as some streaming video, can also appear black when shared because of copy protection.
