StreamLive Pro

Live streaming on a Mac without installing software

Go live from a Mac with nothing to install: the browser studio in Safari or Chrome, the macOS permissions to allow, and when an app is still better.

Updated November 5, 2026 · 6 min read

On a Mac you can go live to YouTube, Facebook and other networks from a browser tab. The StreamLive Pro browser studio runs in Safari, Chrome, Edge or Firefox: you allow the camera and microphone once, choose your networks and go live. There is no app to download, no installer to approve and no plugin to keep updated. What the Mac does ask for is permission: macOS decides which apps may use the camera, the microphone and the screen, and most first-time problems on a Mac come from those three switches.

This guide is for a MacBook or an iMac, a creator, a teacher or a small team who wants to stream without learning streaming software. It also says when installing an app is still the better choice.

Browser studio or an app: the short version

OBS Studio has a Mac version that you download and install; its download page says it supports macOS 13 and newer (obsproject.com download, checked 5 November 2026). Sending OBS to StreamLive Pro is on paid plans, not in the trial: Connect OBS to StreamLive Pro and multistream. StreamLive Pro Studio, our desktop app for Windows and Mac, is not released yet. More on the choice: Browser studio, OBS or a desktop app: which to stream from.

What you need

• A Mac with an up-to-date browser. Safari, Chrome, Edge or Firefox. Which browsers and devices work: Which browsers and devices work with StreamLive Pro.
• A camera. The built-in FaceTime camera works. An external USB webcam, or a camera through a USB capture card, shows up in the browser as one more camera. An iPhone near the Mac can also appear as a webcam through Apple's Continuity Camera, which needs iOS 16 and macOS Ventura or later (Apple Support: Use iPhone as a webcam for Mac, checked 5 November 2026).
• A microphone. The built-in microphone is fine to start. A USB microphone close to your mouth is the cheapest real improvement.
• Internet. Wired through an adapter if you can, or good Wi-Fi. You upload one stream, and StreamLive Pro sends it to each network from its servers, so three networks do not need three times the upload: Upload speed and bitrate for multistreaming.
• An account. The 7-day trial includes the browser studio, 2 destinations and 2 broadcasts of up to 60 minutes. Plans: /pricing?lang=en.

Steps

1. Connect your networks. Open Connections and sign in to YouTube, a Facebook Page you manage, Twitch, Kick, or add a stream key for networks that use one: Connecting your channels — YouTube, Facebook and the rest.
2. Open the browser studio. In Live stream start a new live and choose Browser Studio.
3. Allow the camera and microphone in the browser. The browser asks the first time. Choose Allow. If it never asks or the picture stays black, see the next section.
4. Pick your camera and microphone. In the studio, add the camera as an input and choose the right microphone. The ten-second check shows that picture and sound arrive before you go live: The 10-second camera check before you go live.
5. Add what you need on screen. A logo, a title with your name, slides or a shared window: Add a logo and overlays to your live stream, How to share your screen in a live stream.
6. Add a phone or a guest, if you want. A phone becomes a second camera through a link or QR code: Use your phone as an extra camera. A guest joins from their own browser by link: Guests and invitations — bringing people into the room.
7. Press Record if you want to keep it. Without it, the recording is removed about two hours after the broadcast.
8. Choose the networks and go live. Tick the channels for this broadcast and go live. The studio sends one stream; StreamLive Pro sends it on to each network.

The three macOS permissions

macOS keeps its own list of which apps may use the camera, the microphone and the screen, separate from the browser's own site permissions. Both must allow it.

Step by step for each, with Apple's own pages: My camera does not work in the browser, My microphone does not work in the browser and Screen sharing does not work on my Mac. StreamLive Pro shows no error when a screen share is refused, because cancelling the picker is a normal choice; "nothing happens" is the typical sign of the missing permission.

Safari, Chrome or Edge

All of them run the studio. Two differences to know:

• Recording format. When you press Record, the browser records the program. Chrome, Edge and Firefox record WebM; where a browser cannot, as has been the case in Safari, the studio records MP4. Both play and edit normally in Storage.
• Sound with a shared screen. Each browser has its own picker, and whether the sound of what you share comes along depends on the browser and on what you share. If you need the sound of a video you share, test it before the live.

Keep the Mac steady during a live

• Keep the studio tab visible. A hidden or minimised tab makes the browser slow down video. If you share a window, keep part of the studio visible, or use a second screen.
• Power. Plug in the charger. A long live with the camera on drains a laptop battery.
• Close what competes. Zoom, Teams or another tab can hold the camera. Close them before you start.
• Turn on Do Not Disturb. A notification over a shared screen goes on air.

Common mistakes

• Allowing the camera in the browser and stopping there. macOS has its own switch.
• Not quitting the browser after a permission change. It applies after the browser restarts.
• A Facebook or Instagram link opened inside their app. That small in-app browser often has no camera. Open the studio in Safari or Chrome.
• Expecting OBS in the trial. The trial is browser studio only; OBS and other encoders are on paid plans.
• No Record pressed. The full video is kept only if you press Record.

Where StreamLive Pro fits

On a Mac, StreamLive Pro gives you a live studio in a browser tab: cameras and phone cameras, screen share, titles and logo, guests by link, one stream that goes to several networks at once, the recording kept when you press Record, and Shorts afterwards. It is not a replacement for a full local production app with plugins and many hardware inputs; for that, use OBS and send it to StreamLive Pro on a paid plan. Our own desktop app is not released yet.

Frequently asked questions

Can I live stream from a Mac without OBS?

Yes. The StreamLive Pro browser studio runs in Safari, Chrome, Edge or Firefox on a Mac, with nothing to install, and goes live to several networks at once.

Which browser is best on a Mac?

Safari, Chrome, Edge and Firefox all run the studio. Use the one you already have, keep it up to date, and allow it in the macOS privacy settings.

Why is my camera black on the Mac even though I clicked Allow?

macOS also has to allow the browser to use the camera. Turn the browser on under System Settings, Privacy and Security, Camera, then quit and reopen the browser.

Can I use my iPhone as a camera for the Mac?

Yes, in two ways. Apple's Continuity Camera makes the iPhone a webcam for the Mac, or the iPhone opens a StreamLive Pro link and joins the studio as an extra camera.

Is there a StreamLive Pro app for Mac?

StreamLive Pro Studio for Windows and Mac is not released yet. Today you use the browser studio, or send OBS to StreamLive Pro on a paid plan.

Can I share my screen with sound on a Mac?

It depends on the browser and on what you share. macOS must allow the browser to record the screen; test the sound of a shared video before the live.
