How to Record a Webinar on Mac with Audio
Before a webinar begins, choose the window or screen to capture and test the exact audio sources you need. A moving picture alone does not prove that the presenter, meeting sound, and your microphone will all be in the saved file.
Quick answer
In GiliSoft Screen Recorder for Mac, select the capture area, enable the needed system-audio and microphone sources, and make a 20-second test using the real webinar app. Play that file back before the session; then check the full recording and every split segment afterward.
Grant Only the macOS Permissions the Recording Needs
| Source | macOS setting | When it is needed |
|---|---|---|
| Screen and internal audio | Privacy & Security > Screen & System Audio Recording | Screen capture and supported Mac system sound |
| Microphone | Privacy & Security > Microphone | Narration, voice, or room audio |
| Camera | Privacy & Security > Camera | Presenter webcam or camera-only capture |
| Files and folders | Privacy & Security > Files & Folders | Saving into a protected Desktop, Documents, or other selected location |
After changing a permission, reopen the recorder when macOS requests it. Screen/system-audio permission and microphone permission are separate: enabling one does not automatically enable the other. See Apple's screen and system audio permission guide.
Prepare for a Recording You Cannot Easily Repeat
| Decision | What to prepare | Quality check |
|---|---|---|
| Authorization | Host, speaker, attendee, and policy consent | Confirm before opening sensitive content. |
| Sources | Screen, system audio, microphone, and webcam | Test the exact source and workflow. |
| Continuity | Power, storage, network, auto stop, and auto split | Make the important action easy to follow. |
| Backup | Platform recording or another approved recovery option | Verify the saved file in its real destination. |

Screen Recorded but Webinar Audio Is Missing?
Play the short test file before changing multiple settings at once. If the presenter is silent, check Screen & System Audio Recording permission and the recorder's system-audio source. If your own voice is missing, check Microphone permission and the selected input device. If both are silent, confirm the recording mode and replay the saved file in another player.
Test with the actual webinar app and audio output device. Some protected or restricted sources may not be capturable; headphones can also change which device carries the sound. For a source-by-source walkthrough, see the Screen Recorder for Mac guide.

Play the exact uploaded or shared file on the platform the audience will use.
Record Only What You Are Authorized to Capture
Get the permission required by the meeting, school, employer, client, platform, and applicable local law before recording people, calls, classes, webinars, or private material. Recording requirements vary.
Turn on a Mac Focus such as Do Not Disturb, use demonstration data, and review the final video for names, messages, account identifiers, internal URLs, credentials, and unrelated desktop content.
Record a Webinar on Mac FAQ
Can GiliSoft Screen Recorder for Mac record a webinar?

Why is the screen or system audio unavailable?
Open System Settings > Privacy & Security > Screen & System Audio Recording and allow the recorder. Then select the system-audio source in the recorder and run a short test; reopen the app if macOS asks you to do so.
Why is the microphone or camera unavailable?
In System Settings > Privacy & Security, enable the recorder under Microphone or Camera. Confirm the selected input device and close another app that may already be using it.
How do I prevent private notifications from appearing?
Turn on a Focus such as Do Not Disturb, close private apps and tabs, and record a selected region instead of the full display when possible.
