Choose the audio you actually need
A screen recording is a video of what happens on your display. On a Mac, the built-in tools can record the whole screen or a selected area without installing anything. Microphone audio is your spoken narration. System audio is sound produced by an app, such as a video or game. They are different sources, and macOS treats them differently for privacy.
For most tutorials, a clear microphone voiceover is more useful than raw computer sound. Apple’s take screenshots and screen recordings guide and screen-recording privacy guide are the official references.
Record with the Screenshot toolbar
1. Open the toolbar
Press Shift-Command-5. A small control strip appears near the bottom of the screen. Choose either the icon for recording the entire screen or the icon for recording a selected portion.
2. Set useful options
Click Options before recording. Under Microphone, choose your internal microphone, AirPods, or USB microphone if you want narration. You can also choose where the video is saved and enable “Show Mouse Clicks” when a tutorial needs visible clicks.
3. Frame the video
For a selected portion, drag the border so it includes only the relevant app. Close notifications and private tabs first. A smaller, tidy recording is easier to follow and has a smaller file size.
4. Start and stop
Click Record. To finish, click the stop button in the menu bar, or press Command-Control-Esc. A thumbnail appears briefly; click it to trim the beginning or end before saving.
Use QuickTime Player when it suits you
QuickTime Player is another Apple-provided option. Open it, choose File > New Screen Recording, select a microphone from the options menu, then start. Apple documents the player in its QuickTime screen-recording instructions. The Screenshot toolbar is usually faster; QuickTime is handy if you already use it to play or trim video.
Understand system audio and consent
macOS’s built-in screen recorder is designed to capture the display and an optional microphone. Capturing internal app sound may require a trusted, properly installed audio-routing tool and permission settings, depending on your macOS version and the application. Do not install a mysterious “audio driver” from a search ad just to solve this problem.
Use a safer workflow when possible:
- Record the screen and your narration with the built-in tool.
- Export a permitted audio track from your own project, if one exists.
- Combine them in an editor such as iMovie.
- Listen with headphones before publishing.
For meetings, calls, classes, or copyrighted media, get consent from participants and follow your local law and workplace policy. A technical capability is not automatic permission to record someone.
Fix common recording problems
The app cannot see the screen
Go to System Settings > Privacy & Security > Screen & System Audio Recording and allow the app you are using. Then quit and reopen it. Apple’s privacy settings documentation explains where these controls live.
The narration is silent
Reopen Shift-Command-5, choose Options, and select the intended microphone. Check that the microphone is not muted in Control Center. Make a ten-second test clip before recording a long lesson.
The recording is enormous or blurry
Record only the needed portion, use 1080p for most web video, and make text larger before starting. Keep cursor movement deliberate. A quick primer on basic computer concepts is available at ▶ Watch: Computer Basics (open on YouTube).
A repeatable tutorial workflow
- Write three bullet points for what viewers will learn.
- Close private windows and silence notifications.
- Make a short microphone test.
- Record one task at a time.
- Trim pauses, then watch the final file once.
The built-in toolbar is the best first choice: it is free, private, and documented by Apple. Add extra audio software only after you know why built-in microphone recording is not enough.
How to use advice safely
Technology guidance is most useful when it is tested carefully instead of followed blindly. Product screens and menu names can change after an update, so use the official link in this article as the source of truth when a step does not match your device. Read a step all the way through before clicking it, especially when it involves deleting data, changing a security setting, or buying hardware.
Take a small, reversible action first. For example, make a short test recording before a one-hour presentation, check one startup program before disabling several, or try a free cloud project before moving important data. Write down what you changed and keep a backup of important files. This makes it easier to undo a mistake and identify what actually helped.
Be careful with search results and ads. A page that copies a brand logo is not necessarily official. Check the web address, look for the company’s support domain, and do not give a stranger a password, recovery code, or remote access merely because they sound urgent. Reputable support staff will not pressure you into a risky download.
Check before you share, install, or pay
Before sharing a result online, remove private details. A screenshot can show an email address, calendar notification, browser tab, document name, serial number, or location. Read it at full size, not only as a thumbnail. If the task involves someone else’s account, recording, health information, or device, get their clear permission first. “I did not know” is not a useful privacy setting.
Before installing software, read what it asks to access. A photo editor may reasonably need access to photos; a flashlight, simple timer, or watch-face app usually does not need every contact or account. On a computer, download from the maker’s own site or a well-known official store. On a phone, prefer the App Store or Google Play. Remove software that you no longer use, especially extensions that can read what you browse.
Before paying for an upgrade or service, decide what problem it solves. Compare the ongoing subscription cost with the benefit you will actually use. Keep the invoice, read the cancellation terms, and use a payment method that gives you a record of the transaction. A low upfront price does not help if the product has no support, no return policy, or a confusing renewal.
Keep a simple troubleshooting record
When a task does not work, record the model of the device, operating-system version, application version, exact error message, and the last action that succeeded. Do not post account numbers, passwords, recovery codes, private files, or complete serial numbers in a public support forum. This small record helps official support identify the issue without turning troubleshooting into random trial and error.
Try one safe change, test it, and then decide what to do next. For example, if a page will not load, first test another website or network before resetting a whole device. If an app crashes, update it and restart before uninstalling it. If a security warning appears, stop and verify it through a known official channel instead of clicking through it. A calm, ordered approach protects both your time and your data.
Finally, use information as a guide rather than a diagnosis. If a device becomes hot, loses data, reports a possible account compromise, or behaves in a way that could affect safety, pause the task and contact the manufacturer, a qualified repair provider, or the relevant account-support channel. Good technical habits are usually simple: keep software current, protect accounts, make backups, and make one informed change at a time.
