In short
Check your institution's recording policy and ask the lecturer first. Then sit near the front, put the MacBook on the desk with the lid open, and start a recording by hand in QuickTime Player or a notetaker. The lecture arrives on the microphone, and transcription follows the Mac's language.
To record a lecture on a Mac, get permission first: check your institution's policy on recording teaching and ask the lecturer. Then sit near the front, put your MacBook on the desk with the lid open, and start a recording by hand, in QuickTime Player for a plain audio file or in a notetaker for a transcript as well. An in-person lecture reaches the Mac's microphone, and a transcript made on the Mac is in the Mac's language.
This guide covers permission, placement, the steps, and what to do with a transcript afterwards. For a class you join over Zoom or in a browser, see recording an online class on a Mac.
How to record a lecture on a Mac
- Check the rules. Look up your institution's policy on recording lectures, and any rule for this course.
- Ask the lecturer. Before the lecture, in person or by email: "Would you mind if I recorded today's lecture for my own notes?"
- Sit near the front. Close to the lecturer, or to a loudspeaker if they use a microphone.
- Set the Mac's language to the language of the lecture if it differs from what the Mac uses.
- Put the MacBook on the desk, lid open. Keep it clear of papers and your hands.
- Start the recording when the lecture begins.
- Stop it at the end, and check that the file or transcript is there before you leave.
- Keep the recording to yourself unless you were told you can share it.
Permission comes first
A lecture is someone's work, delivered to a room of people who did not all agree to be recorded. Three separate things can apply:
- The institution's policy. Many universities and schools have one: some allow personal recording, some forbid it, some leave it to the lecturer. Some already record lectures and publish them to students, which may make your own recording unnecessary.
- The lecturer's wishes. Even where recording is allowed, asking is courteous and many lecturers will say yes. Some sessions, such as seminars with personal discussion, are more likely to be a no.
- The law where you are. Recording laws differ, and some places require everyone's agreement to record a conversation. Other students asking questions are part of the recording.
If the answer is no, take notes by hand. A recording made against a clear rule can have academic consequences, whatever the law says.
Disability accommodations are a separate route
If you need recordings because of a disability, you usually do not have to negotiate lecture by lecture. Many institutions arrange recording as an adjustment through their disability or accessibility service, which tells lecturers on your behalf. Go there first. The arrangement often comes with conditions, such as not sharing recordings and deleting them at the end of the course. Other options, such as live captions or a note-taker, may also be available; live captions for meetings on a Mac compares what a Mac can do by itself.
Where to put the MacBook
A lecture hall is harder to record than a meeting room: the speaker is far away, the room is large and echoes, and there is noise around you.
| Situation | What helps |
|---|---|
| Small room, no microphone | Sit in the first two rows, laptop facing the front |
| Large hall, lecturer uses a microphone | Sit near a loudspeaker; the amplified voice is clearer than the direct one |
| Lecturer walks around | Sit centrally; accept that some parts will be quieter |
| Noisy row | Move; keyboard typing next to the microphone is louder than the lecture |
Keep the lid open: the built-in microphones are in the case, and closing it can muffle or switch them off. If you type notes during the lecture, your keystrokes will be loud on the recording; an external microphone pointed at the front helps, as does writing on paper. Recording an in-person meeting with a MacBook goes further into placement and rooms.
Transcription and language
A transcript makes a recording searchable: you can find the part about a topic without listening to an hour of audio. Speech recognition on a Mac works in the language the Mac is set to. If your lectures are in a different language from your Mac, change it before the lecture in System Settings › General › Language & Region. Mac transcription languages lists what is supported.
Technical terms, names and formulas are where transcripts go wrong most. Check them against your slides or the reading list.
How Notey fits into this
Notey is a Mac app for Apple silicon and macOS 26 or later that records and transcribes on the Mac. A lecture is not a call, so Notey will not notice it; you start it yourself.
- Download Notey and open it. Allow Microphone when macOS asks. No account is needed.
- If the lecture is not in your Mac's language, change the Mac's language in System Settings › General › Language & Region and restart Notey. Notey has no language picker per recording; it follows the Mac.
- Press Start when the lecture begins. A red dot and the elapsed time show in the window, the menu bar and the floating button while it records.
- Press Stop at the end.
The lecture arrives on the microphone track, so the whole lecture, and every question from the room, is on one track and labelled as your side. People in the room are not told apart. The transcript is written as the lecture goes, on the Mac, and the audio stays on your disk. After an English lecture, Notey reads the recording again on your Mac and keeps the words its recognisers agree on; lectures in other languages keep the live transcript.
Afterwards, ⌘K searches every recording by what was said, and each transcript line plays from its timestamp. If you have an account, you can ask for a summary, which is labelled as AI-generated and sent as transcript text only. Check it against your slides before you revise from it.
After the lecture
- Write a short summary in your own words the same day. It is what you will revise from; the recording is for checking.
- Mark the moments you need to hear again rather than re-listening to the whole thing.
- Delete recordings you no longer need, especially if the arrangement says so.
Lectures and seminars are one kind of meeting among many; types of meetings and the notes each one needs compares them.
Frequently asked questions
Is it legal to record a lecture?
It depends on where you are and on your institution's rules. Many universities have a policy on recording teaching, and some lecturers or classes say no. Ask the lecturer and check the policy before you record.
Can I record lectures if I have a disability?
Many institutions allow recording as an adjustment for disabled students, arranged through their disability or accessibility service. Ask there; the arrangement usually comes with conditions such as keeping the recordings to yourself.
Can a MacBook's microphone record a lecture?
In a small room, from near the front, usually well enough for a transcript. In a large hall the lecturer is far away and the room echoes, so sit close to them or to a loudspeaker, or ask whether the institution already records the lecture.
Can I share a lecture recording with classmates?
Usually not without permission. Lecture content often belongs to the lecturer or institution, and other students may be heard asking questions. Keep recordings for your own study unless you have been told otherwise.
How do I get a transcript of a lecture on a Mac?
Record with an app that transcribes as it goes, or record first and transcribe the file afterwards. On-device transcription keeps the recording on your Mac. Set the Mac's language to the language of the lecture first.
