Record Your Mac Screen With Audio — System Sound and Mic, Built In
Record your Mac screen with both system audio and microphone using SulusCast. The privacy-first fix for macOS's missing internal audio recording. No plugins, no setup — just press record.
Everything You Need for Mac Screen Recording with Audio
SulusCast solves the biggest frustration with Mac screen recording — capturing internal audio — and adds professional features on top
System Audio Capture Built In
macOS does not capture internal audio by default. SulusCast solves this natively — no BlackHole, no Loopback, no virtual audio drivers required. Enable system audio in SulusCast's settings and it records app sounds, music, and notification audio alongside your screen without any extra configuration.
Microphone and System Audio Simultaneously
SulusCast records your microphone and system audio at the same time in a single recording. Narrate your screen while keeping all the original application sounds — perfect for software tutorials, walkthroughs, and presentation recordings on Mac.
Up to 4K at 60fps on macOS
SulusCast is natively optimized for macOS and records at resolutions up to 4K at 60 frames per second. Every screen recording is sharp, smooth, and professional — ideal for Retina displays on MacBook Pro and iMac.
Webcam Overlay While Recording
Add a picture-in-picture webcam overlay to any Mac screen recording with audio. Record your face alongside your screen for a more personal, engaging experience — great for tutorials, product demos, and async video messages.
Instant Shareable Links
Stop recording on your Mac and SulusCast generates a shareable link immediately. No uploading, no file transfers. Paste the link anywhere and your viewers get instant access to the full recording with audio.
Free with No Watermarks
SulusCast's Studio Mode is completely free for personal use on Mac with no watermarks, no time limits, and no hidden fees. Download SulusCast's free screen recorder to start recording with audio on Mac today.

SulusCast vs Built-in Mac Recorders for Audio
Understand why the built-in macOS tools fall short for audio recording and how SulusCast fills the gap
SulusCast vs macOS Cmd+Shift+5
The macOS built-in screenshot toolbar (Cmd+Shift+5) can record your screen but cannot capture system audio. It records microphone only. SulusCast captures both system audio and microphone natively on macOS without any additional tools — making it the far superior choice for anyone who needs audio in their Mac screen recordings. See all reasons to use SulusCast on Mac.
SulusCast vs QuickTime Player
QuickTime Player's screen recording feature also lacks internal audio capture on modern versions of macOS. Like Cmd+Shift+5, it can only record the microphone. SulusCast removes this limitation entirely, capturing system audio natively alongside microphone input in every recording.
SulusCast vs OBS Studio for Mac
OBS Studio can record Mac screen with audio, but it requires installing and configuring a virtual audio device like BlackHole to capture system sound — a multi-step process that is easy to get wrong. SulusCast handles all audio routing automatically with zero configuration. Compare all screen recording software.
SulusCast vs Loom on Mac
Loom records Mac screen with audio and is a popular tool for async video, but it charges $18/month for professional use and adds watermarks on the free plan. SulusCast is significantly more affordable, privacy-first, and offers Studio Mode completely free with no watermarks. See the full SulusCast vs Loom comparison.
