How to Screen Record on Mac: 4 Methods, Audio Fixed
Summary
To screen record on Mac, press ⌘ ⇧ 5, choose the entire screen, a window or a portion, and click Record. Stop with ⌘ ⌃ Esc. The file saves as a .mov on your Desktop. The built-in tool records your microphone but not system audio, so you need a free driver like BlackHole or a third-party recorder for that. Trim in QuickTime, compress with ffmpeg, and only pay for an app when you need webcam bubbles, effects or heavier editing.
Here is how to screen record on Mac: press ⌘ ⇧ 5, pick entire screen, a window, or a portion, and click Record. Stop it from the menu bar. The file lands on your Desktop as a .mov. That covers 90% of cases, costs nothing, and needs no install. The other 10% is system audio, long recordings, and clean editing, and that is where the built-in tool runs out.

What is the fastest way to screen record on Mac?
The Screenshot toolbar. Press ⌘ ⇧ 5 and a small bar appears at the bottom of the screen. Two groups of buttons: three for still captures, two for video. The video pair is "Record Entire Screen" and "Record Selected Portion". Apple's guide also documents recording a single window, and lists every option in Apple's own screen recording guide.
Click one, click Record, work. When you are done, click the Stop button in the menu bar, or press ⌘ ⌃ Esc. You do not need to hunt for the icon.
Three details that save time:
The shortcut works on macOS Mojave (10.14) and later, on Intel and Apple Silicon.
Recordings are saved as
.movfiles named "Screen Recording" plus the date and time.A floating thumbnail appears in the bottom-right corner after you stop. Click it to trim. Swipe it right to save and dismiss.
If you have a specific problem like "send a bug repro to a teammate in 30 seconds", this solves it. If not, keep reading.
Which options in the toolbar actually matter?
Click Options in the bar. Most of the menu is noise. Four items are worth setting once:
Save to. The default is the Desktop. A folder of recordings you will delete next week belongs somewhere else, such as
~/Movies/Captures. Your Desktop stays clean.Timer. Choose 5 or 10 seconds. It gives you time to switch to the right app, close the notification you did not mean to show, and put your hand back on the mouse.
Microphone. Pick the mic you actually want, or None. The default is often the built-in mic, which picks up fan noise and keyboard clatter.
Show Mouse Clicks. Turn it on for tutorials. Viewers see a circle where you click. Turn it off for silent bug repros where you want a clean frame.
Everything else, including Remember Last Selection and the HDR or SDR capture format, is a preference. Set it once and forget it. If you plan to share the file with people who use older players, SDR is the safer pick.
Can you record only part of the screen, or one window?
Yes, and you should. Recording the entire screen on a 5K display produces a large file and shows your menu bar, your dock, and whatever notification arrives mid-take.
"Record Selected Portion" gives you a draggable frame. Drag the edges to resize it. Drag the frame itself to move it. Turn on Remember Last Selection and the same rectangle comes back next time, which matters when you record the same app window every week.
"Record a window" works differently. Hover over the window and click it. The recording follows that window and ignores the rest of the desktop. It is the cleanest option for software demos because nothing else leaks into the frame.
The skip case: if you are recording a full-screen app, a game, or anything that changes spaces, use the entire screen. Window capture is happiest when the window stays put.
How do you record Mac system audio?
You cannot, with the built-in tools. This is the single biggest gap, and every guide that skips it wastes your time.
The Screenshot toolbar records your microphone. It does not record the sound your Mac plays: a video call, a browser tab, an app's notification sounds. The same holds for QuickTime Player, whose File > New Screen Recording command opens the same toolbar on modern macOS.

Your options, in order of effort:
Record voice only. Use a decent external mic and narrate. For tutorials this is usually what you want anyway. A clean voice track beats a muddy mix of voice plus app sound.
Install a virtual audio driver. BlackHole is a free, open-source loopback driver. You route system output through it, then select it as the input in the toolbar. Setup happens in Audio MIDI Setup, and you need to build a Multi-Output Device so you can still hear what you record. Do it once, and it keeps working.
Use a dedicated recorder. Third-party recorders handle internal audio without driver gymnastics. Camtasia, ScreenFlow, and CleanShot X all do. More on those below.
One more caveat. Streaming services such as Netflix, Prime Video, Apple TV+, and Disney+ use DRM. Their video often records as a black rectangle. That is by design, and no setting changes it.
Can you screen record from the Terminal?
Yes. If you live in a shell, this is the sleeper option:
# Record the screen for 30 seconds and save it to a folder of your choice
screencapture -v -V 30 ~/Movies/Captures/repro.movThe -v flag records video. -V 30 stops after 30 seconds. Leave out -V and the recording runs until you stop it with Ctrl+C. No toolbar. No clicks. You can wire it to a keyboard launcher or a script that records a reproduction case on demand.
It records the screen only, and it has the same audio limits as the toolbar. For a quick, repeatable capture, though, it is hard to beat. Nothing to install. The binary is already on your Mac.
When does QuickTime Player still make sense?
Less often than older tutorials claim. On Macs running High Sierra or earlier, QuickTime Player was the way to record the screen: File > New Screen Recording, then Control-Command-N. On anything modern, that command opens the same ⌘ ⇧ 5 toolbar. You gain nothing by taking the longer route.
What QuickTime does well is the step after recording. Open the .mov, then Edit > Trim, and drag the yellow handles to cut dead air from the start and end. File > Export As lets you pick a lower resolution, which is the quickest way to get a multi-gigabyte capture down to something you can attach to an email.
Here is what you should expect on file size. Screen recordings are saved at your display's native resolution, so a Retina display produces a heavy file fast. If the destination is a chat app or a ticket, shrink it first. An ffmpeg one-liner does it in a single pass:
# Re-encode to H.264 at a lower quality target; larger CRF = smaller file
ffmpeg -i "Screen Recording.mov" -vcodec libx264 -crf 28 -preset medium output.mp4Pick a CRF between 23 (higher quality) and 30 (smaller file) and test on a short clip first.
Do you need a third-party screen recorder?
Probably not for bug reports. Probably yes if you record weekly, narrate, or ship tutorials. Here is the honest split.

Stay with the built-in tool if you record short clips, one person watches them, and trimming in QuickTime is enough. It is free. It has no account, no watermark, and no upload step.
Move to something else if you need any of these: internal audio without a driver, a webcam bubble, zoom-on-click effects, scrolling capture, or editing that goes beyond trimming the ends.
A short, concrete set of paths:
Setapp. One subscription that bundles 270+ Mac apps, CleanShot X among them. Pay once a month for the bundle instead of buying each recorder separately. The sensible route if you would use two or three of the bundled apps anyway.
Descript. You edit video by editing the transcript. Delete a sentence in the text and the matching footage disappears. Strong for narrated walkthroughs, though media hours are metered even on paid tiers.
VEED. A browser-based editor with auto-subtitles and translation. It runs on any OS, so it fits a team that is not all on Macs. The free tier watermarks exports.
Kapwing. Another browser editor, built around collaborative editing and subtitle generation. Good when several people need to touch the same cut.
Check each tool's binary size, permissions, and pricing model before you commit. A recorder needs Screen Recording permission in System Settings, so it can see everything on your display. That is a reason to be picky.
Why is your recording blank, or missing the screen?
Two causes cover nearly every failure.
Permissions. If a recording comes out empty or an app cannot capture, open System Settings > Privacy & Security > Screen & System Audio Recording and enable the app. Quit and reopen it after you change the setting. macOS only reads the permission at launch.
Protected content. DRM video, as covered above, records as black. The workaround is not a workaround. Do not try to defeat it.
A third, quieter one: a recording that stops immediately or never saves is usually a full disk. A 10-minute capture on a Retina screen is not small. Check free space first.
What would we actually do?
For a one-off bug repro: ⌘ ⇧ 5, record a window, Stop, drag the thumbnail into the ticket. Total time, under a minute.
For a recurring tutorial: buy a decent USB mic, record voice only with the built-in toolbar, trim in QuickTime, and compress with ffmpeg. No subscription. No new apps. If you need system sound and polish, install BlackHole first, and only then look at a paid recorder.
For a team on mixed machines: a browser editor, so nobody needs to install anything.
One tool. One job. Start with the one already on your Mac.
