How To Screen Record On A Mac

Tips
1

I’m trying to screen record on my Mac for a tutorial video, but every time I use the built-in tools I either lose the system audio, the mic sounds bad, or the recording quality looks blurry. I’m not sure if I should use QuickTime, a shortcut, or third-party apps, and I’m worried I’m changing the wrong settings. Can someone walk me through the right way to screen record on a Mac with clear video and sound, and what settings or tools I should use?

You are running into three separate issues, so break them up and fix each one.

  1. Use the right tool
    If you want system audio and clean mic, skip only using the built in screenshot tool.

Free options that work well:
• OBS Studio
• BlackHole (virtual audio device) + QuickTime
• IShowU Audio Capture (older, still works on some systems)

Paid but simpler:
• Screenflow
• Camtasia
• CleanShot X (lighter, nice UI)

For best quality and control, OBS is solid.

  1. Get system audio and mic at the same time
    macOS blocks direct internal audio capture, so you need a virtual device.

Typical OBS + BlackHole setup:

  1. Install BlackHole (2ch is enough).
  2. Open Audio MIDI Setup.
    • Create a “Multi Output Device”.
    • Check your speakers or headphones and BlackHole.
  3. Set the Multi Output Device as your system output in macOS sound settings.
  4. In OBS, go to Settings > Audio.
    • Add “Audio Input Capture” for your mic.
    • Add “Audio Output Capture” and select BlackHole for system sound.

Now your ears hear the audio, and OBS records it.

  1. Fix the blurry video
    A few common problems:

• Wrong resolution
In OBS, set:
• Base (Canvas) Resolution: match your display, often 1920x1080 or 2560x1440.
• Output (Scaled) Resolution: usually 1920x1080 for tutorials.

• Low bitrate
For 1080p at 30 fps, use at least:
• 8000 kbps video bitrate for clear UI text.
For 60 fps, target 10000 to 12000 kbps.

• Encoder
Use x264 if your CPU can take it.
Preset: “veryfast” or “faster” for a modern Mac.
If you have Apple Silicon, use “Apple VT H264 Hardware Encoder” for lower load.

  1. Improve mic quality
    • Use an external USB mic or even wired iPhone earbuds instead of the laptop mic.
    • In OBS, add filters on the mic:
    • Noise Suppression
    • Noise Gate
    • Compressor

Quick settings that work for most rooms:
• Noise suppression: RNNoise option.
• Compressor: Ratio 3:1, Threshold around -18 dB, Output gain +3 dB or so.

  1. If you want to stick with the built in tool
    Use Shift + Command + 5.
    • For sharp output, make sure your display is 100 percent scaling in System Settings > Displays. Scaling up or down softens text.
    • For audio, select your mic in the recording options.
    For system audio with it, you still need BlackHole or similar and record it via a second app like QuickTime, then sync audio in editing, which is a bit of a pain.

If you want simple and do not want to mess with virtual devices, Screenflow is usually the least annoying paid option for Mac tutorials. It records screen, system audio, and mic in one go and lets you fix levels later.

If you’re hitting all three problems (no system audio, junky mic, blurry video), the temptation is to nuke the built‑in tools from orbit and live in OBS forever. @mike34 covered that path really well, so I’ll throw in some alternates and a slightly different angle.

First, I actually wouldn’t jump straight to virtual audio drivers unless you really need them. They work, but they’re one more thing to break after a macOS update.

1. Use a recorder that handles system audio for you

If you’re willing to pay a bit and want simpler than OBS:

  • ScreenFlow or Camtasia:
    They both install their own system audio capture component.
    You get:
    • Screen + mic + system audio in one click
    • Separate audio tracks on the timeline so you can fix volume later
    • Basic editing without going into a full NLE like Final Cut

They solve 90% of your problem in one place: you record, then tweak levels and trim. Zero messing with Audio MIDI Setup.

If you want to stay free but don’t love OBS’s complexity, try:

  • CapCut Desktop or DaVinci Resolve + QuickTime:
    Record with QuickTime, then edit & sharpen in CapCut / Resolve.
    For system audio, you’d still need something like BlackHole, but the editing part is cleaner than doing everything in OBS for some folks.

2. Fix the mic without going audiophile

You don’t need filters and compressors right away if that’s overwhelming.

Try this shorter path:

  • Use anything that’s not the built‑in laptop mic:
    • Wired earbuds with a mic
    • A USB podcast mic if you have one
  • Record your voice separately in QuickTime or Audacity:
    • Do screen capture with whatever tool you want
    • Record narration at the same time in a second app
    • Sync them after in iMovie / CapCut / ScreenFlow

This sounds annoying, but it often gives you cleaner voice audio because you can redo the VO or process it without trashing the screen recording.

3. Deal with blurriness the “lazy but effective” way

Instead of only playing with bitrate like @mike34 said, also:

  • Match your capture size to what viewers will see.
    If your Mac display is 2560x1600 but you upload in 1080p, record a 1920x1080 region of the screen or set your display temporarily to 1920x1080.
    That way you’re not relying on YouTube or your editor to downscale small UI text for you.

  • In your editor, export at:

    • 1080p
    • 15–20 Mbps for H.264
      For tutorial UI, I’d rather slightly overkill bitrate than save 200 MB and get fuzzy text.

4. If you really want to stick with Shift + Command + 5

You can make the built‑in recorder usable if you accept a bit of juggling:

  • Set display resolution to something close to 1080p so the capture is cleaner.
  • Use a decent external mic and select it in the options.
  • For system audio:
    • Play audio out through speakers
    • Let your external mic pick it up at low volume
    • Then do a light noise reduction pass in your editor

Is that ideal? No. But it avoids virtual audio devices and is “good enough” for internal tutorials or non‑public stuff.

5. What I’d actually do for a tutorial series

If you plan to record more than once or twice:

  • Get ScreenFlow or Camtasia
  • Plug in a cheap but decent USB mic
  • Set display to 1920x1080 while recording
  • Record mic + system audio + screen in one shot
  • Tweak levels and export at 1080p ~15 Mbps

It’s not the most “pro” stack, but it saves you from wrestling with OBS scenes, virtual outputs, and sync issues every single time just to show someone how to click some menus.

Skip OBS for a second and zoom out: your three problems are actually three separate dials you can tune.

1. Built‑in tools are fine… if you change how you work

I disagree a bit with the idea that macOS’s recorder is only “good enough for internal stuff.” It can look sharp if you:

  • Record only what matters
    • Use the region capture so you are not scaling a giant 4K canvas down to 1080p.
  • Zoom UI, not bitrate
    • Crank app font sizes, browser zoom, and macOS display scaling so buttons and text are big. Tutorial videos with big UI survive compression much better.

For your use case, half the “blurry” feel is usually tiny UI, not low quality.

2. System audio without going deep into virtual drivers

Where I part ways with @mike34 a bit is on avoiding virtual drivers entirely. If you plan more than a couple of videos, one minimal driver can be worth it, as long as you keep the stack simple:

  • Install a single virtual audio device
  • Set it as output on the Mac
  • Route that into whatever recorder you choose

No filters, no complex routing. One trick only: treat the virtual device like your “speakers.” This lets you stick with the macOS screen recorder or a simple app and still capture system sound reliably.

3. Mic quality: fix the room before the gear

You do not necessarily need a new mic immediately.

  • Kill room echo first
    • Record in a smaller room, add soft stuff: curtains, couch, clothes.
  • Get close to whatever mic you have
    • 10–15 cm from your mouth, slightly off axis, drops room noise and keyboard clack a lot.
  • Keep input gain modest
    • Then normalize in your editor later so you are not riding the red.

Once that is dialed in, then consider upgrading hardware if it still sounds rough.

4. Workflow that avoids “all in one” frustration

Instead of hunting for a single magic tool, think of a 3‑step chain:

  1. Capture
  2. Clean audio
  3. Export sharp

For example:

  • Capture with macOS recorder
  • Edit audio separately in Audacity or a DAW
  • Drop everything into a lightweight editor for cuts and export

This keeps each piece dead simple and usually breaks less when macOS updates.

5. About using a dedicated “How To Screen Record On A Mac” style tool

Tools that brand themselves as a one‑stop “How To Screen Record On A Mac” solution try to wrap all of that into one package. Pros and cons in practice:

Pros

  • Screen, mic, and system audio managed in one place
  • Often have templates for cursor highlights and callouts that make tutorials more readable
  • Timeline view so you can nudge voiceover against visuals without a full pro editor

Cons

  • Paid, with upgrades when macOS changes codecs or audio rules
  • Heavier than the native recorder, so more chance of stutter on older Macs
  • Lock‑in: project files are rarely portable to other apps

So I would not rush into a big suite unless you know you will record a lot and want built‑in editing.

6. What I’d actually test for your specific pain points

Run three quick experiments, no big setup:

  1. Blurry check

    • Set display to 1920×1080 or zoom the app to 125–150 percent.
    • Record 20 seconds with Shift + Command + 5.
    • Watch it full screen at 1080p.
      If it is legible, your “blurry” problem is mostly scaling and UI size.

  2. Mic sanity check

    • Same clip, but sit closer to your mic in a quieter corner and drop input gain slightly.
      If that sounds better already, room and distance were the culprits.

  3. System audio minimal setup

    • Add one virtual device, route system output through it for one test recording.
      If that works consistently, keep that simple routing and do everything else as you like.

Once those three checks pass, it does not really matter whether you stick with the macOS recorder, one of the “How To Screen Record On A Mac” type apps, or something like the stack @mike34 described. The key is keeping each problem isolated and solved once instead of wrestling with three at the same time.
