An AI interview assistant for Mac needs three things to work: a native app that supports your version of macOS, two privacy permissions, and a clean path for your meeting's audio. With CoPilot Interview, which runs on macOS 12 or later, you download a zip, unzip it, open the app and answer the permission prompts. From then on it shows live captions of the interviewer's question, followed by a structured answer in about 2 seconds.
Most problems on a Mac have nothing to do with the AI. They come from a permission that was never granted, a meeting app sending sound to the wrong device, or Bluetooth earbuds degrading the audio. This guide covers setup in order, how Zoom, Teams and Meet audio reaches the app, a pre-interview test built on the free AI mock interview, and fixes for the common failures.
You don't need an account to start. The free plan gives you 15 minutes every day, enough to finish every step below.
What your Mac needs
CoPilot Interview is a desktop app, not a browser extension, so the list of supported systems is specific: macOS 12 Monterey or newer on both Apple Silicon and Intel Macs, plus Windows 10 and later. There is no Linux build.
Speech-to-text and the AI models run in the cloud, so there is no GPU requirement. Headroom matters more, because during an interview you run a meeting app, a browser and the assistant at once.
| Component | Minimum | Recommended |
|---|---|---|
| macOS | macOS 12 Monterey | macOS 14 or later |
| Processor | Dual-core, Apple Silicon or Intel | Apple Silicon or a quad-core Intel chip |
| Memory | 8 GB | 16 GB |
| Free disk space | About 1 GB | A few GB for updates and logs |
| Audio | Any working microphone | Wired headset or USB microphone |
| Internet | A few Mbps, stable | Wired Ethernet or strong 5 GHz Wi-Fi |
| Display | One laptop screen | 1080p, or a second display |
If your Mac handles a Zoom call with the camera on, it can run the assistant beside it. Our system requirements guide for AI interview assistants explains each line, and the free AI interview assistant page covers what the app does on Mac and Windows.
Download, unzip and open the app
There is no installer wizard on a Mac: you unzip the app and run it.
- Download the macOS build. In the download section of the CoPilot Interview homepage, choose the macOS button. The file is
CoPilot Interview.zip. - Unzip it. Double-click the zip in your Downloads folder, and Finder extracts the app next to it.
- Move it to Applications. Drag the app into Applications, so the permissions you grant belong to the copy you actually open.
- Open it. The first time you open an app downloaded from the internet, macOS asks whether you're sure. Confirm, and after that it opens normally. If macOS blocks it instead, Apple's guide to safely opening apps on your Mac explains the Open Anyway button in Privacy & Security.
- Skip the signup. The free plan needs no account and includes 15 free minutes every day, sessions up to 15 minutes, the free AI models and all four modes, including Mock Interview.
Do this at least a day before your interview. Permission changes on macOS sometimes need an app restart, and you don't want to find that out five minutes before a call.
The first-launch permission prompts, explained
On first launch, CoPilot Interview asks macOS for two permissions. Each one controls something different.
| Permission | Where to change it | What it enables | Needed for the mock interview? |
|---|---|---|---|
| Microphone | System Settings > Privacy & Security > Microphone | Hearing your voice. In Mock Interview mode, the microphone is the only audio the app captures. | Yes |
| Screen & System Audio Recording (Screen Recording on earlier versions) | System Settings > Privacy & Security, same name | The coding-mode screen capture tools, and capturing the sound your Mac plays, which is how the app hears the interviewer | No |
- Microphone. macOS shows a standard dialog; click Allow. If you click Don't Allow by mistake, Apple's page on controlling microphone access on Mac shows where to turn it on.
- Screen and system audio. On current macOS, recording your screen and recording the sound your Mac plays share one privacy setting, described in Apple's guide to screen and system audio recording access. If you only practice with the mock interview, it can wait. For live captions of another person, or for the screenshot tools, turn it on.
- Restart after granting. Quit fully with Command-Q and reopen. macOS often applies a new permission only after the app relaunches.
- On macOS 12 Monterey, the same settings live under System Preferences > Security & Privacy > Privacy.
macOS never lets an app capture audio you haven't allowed, so these prompts are normal. If captions stop after an app or macOS update, check these two settings first.
How Zoom, Teams and Meet audio reaches the app
Your Mac handles two separate audio streams during a call. The microphone carries what the room hears: your voice, your keyboard, the fan. System audio is what your Mac plays through its speakers or headphones, and in a video call that is the interviewer's voice.
Microphone access alone lets an app transcribe you, but not the person asking questions. CoPilot Interview captures both your microphone and a copy of the sound your Mac is already playing. Because it reads that playback stream instead of plugging into one meeting app, it works the same whether the call runs in the Zoom app, the Teams app, or Google Meet in Safari or Chrome.
That is the main reason it runs as a desktop window rather than a browser extension: an extension can usually reach only one tab's audio, so it loses the interviewer when the call is in a desktop client. When you compare AI interview assistants, check how each one gets the interviewer's audio on macOS. Our explainer on how AI interview assistants capture system audio covers the details, including why older Mac setups needed a virtual audio device.
Headphones or speakers?
| Setup | What the app hears | Verdict |
|---|---|---|
| Wired headphones | The interviewer cleanly through system audio; you through the microphone | Recommended |
| Built-in speakers | Both voices, but the interviewer can echo back into your microphone | Works; keep the volume moderate |
| Bluetooth earbuds | Both voices, but earbuds can drop to a lower-quality mode while their mic is in use, which garbles captions | Use wired if you can |
| Microphone only (system audio not allowed) | Your voice and a faint, echoey copy of the interviewer; nothing of theirs once headphones go on | Fix the permission |
- Choose devices in the meeting app before the call. Set the speaker and microphone to the ones you tested with. Our guides to using AI in a Zoom interview, an AI assistant on Microsoft Teams and an AI assistant on Google Meet walk through each app.
- Plug in headphones before you start a session. System audio capture follows the active output device, so connecting headphones, a dock or a monitor with speakers mid-call can move the sound away from what the app captures.
A pre-interview test routine using the free AI mock interview
Run this the day before, on the same Mac, network and headphones you will use. It takes about 15 minutes and checks both halves of the audio path.
- Set up as you will on the day. Plug in your headphones, join the network you'll use, and close apps and browser tabs you don't need.
- Run the audio check. On the app's setup screen, use the audio check to confirm your microphone picks you up.
- Do a short mock interview. Open Mock Interview mode, paste your résumé and the job description, and choose three questions. The AI reads each question aloud and you answer out loud. Each answer gets a score out of 10, what to fix and a model answer, then a report card at the end. This proves the microphone path works and doubles as a warm-up.
- Test the interviewer side. Mock Interview captures only your microphone, so it can't confirm system audio. Start a short Candidate Mode session and have a friend call you on Zoom, Teams or Meet and read two questions. The captions should show their words, and a structured answer should appear about 2 seconds after each question ends.
- Try the coding tools if you have a technical round. Paste a screenshot of a practice problem and check that coding mode returns complete code, its complexity and an example run.
- Write down what worked. Note the microphone and speaker selected in the meeting app so you can match them on the day.
Troubleshooting on macOS
Work down this table in order. It's sorted roughly by how often each cause is the real one.
| Symptom | Likely cause | Fix |
|---|---|---|
| No captions at all | Microphone permission off, or granted but not applied | Turn the app on in Privacy & Security > Microphone, quit with Command-Q and reopen |
| Captions show only your voice | System audio isn't being captured | Turn the app on under Screen & System Audio Recording, relaunch, and check the meeting app's speaker setting |
| Captions stopped mid-call | The output device changed: headphones, a dock or a Bluetooth switch | Reselect the device in the meeting app, then restart the session |
| Captions garbled or half missing | Bluetooth earbuds in a low-quality mode | Switch to wired headphones or a USB microphone |
| Screenshot tools fail | Screen recording permission missing | Enable it in Privacy & Security, then relaunch |
| Answers arrive slowly | The network, not your Mac | Use Ethernet or move closer to the router; pause large downloads and syncing |
| The app won't open | macOS blocked it, or your Mac runs a version older than macOS 12 | Use Open Anyway, check your version under Apple menu > About This Mac, or download the zip again |
If a permission already shows as on but the problem persists, toggle it off and on, then relaunch. If the app is missing from a list, click the add button below the list and choose it from Applications.
Slow answers usually trace back to Wi-Fi rather than the model; our breakdown of where AI interview assistant latency comes from shows where the seconds go. Still stuck? A two-minute dry run with a friend surfaces nearly every issue, and you can email support@copilotinterview.com.
On the day: running it beside your call
- Open the app before you join, and keep the headphones and device selections you tested.
- Give each window room. A second display gives the meeting and the app their own space.
- Let it listen. In Candidate Mode, captions appear as the question is asked. Press Answer, or let it answer automatically when the question ends.
- Use the answer as structure, not a script. Explain it in your own words and check any example before you say it aloud.
Follow the rules of the employer or assessment you're in — many people use it only to practice, which works on the free plan. If you're still deciding whether a real-time interview assistant suits you, read how the live flow works first.
On privacy: session files stay in your own Documents folder. Audio is streamed in short encrypted segments through CoPilot Interview's proxy to a speech-to-text model, and the question text goes to the AI model you chose; nothing is kept on its servers beyond the request. The security page has the details.

Does CoPilot Interview work on Apple Silicon and Intel Macs?
Yes. It runs on macOS 12 Monterey or newer on both Apple Silicon and Intel Macs. 8 GB of memory works, and 16 GB is more comfortable with a meeting app and browser open.
Which macOS permissions does an AI interview assistant need?
Two. Microphone access lets the app hear you. Screen & System Audio Recording (Screen Recording on earlier versions) covers the screen capture tools and the sound your Mac plays, which is how the app hears the interviewer. The mock interview needs only the microphone.
Why do the captions show only my voice?
The app is getting your microphone but not your Mac's system audio. Turn the app on under Screen & System Audio Recording in Privacy & Security, quit and reopen it, and check that your meeting app plays sound through the device you tested.
Should I use headphones or speakers on a Mac?
Wired headphones work best. The app reads the interviewer's voice from system audio, so headphones don't block it, and they stop echo into your microphone. Bluetooth earbuds can drop to a lower-quality mode while their mic is in use, which garbles captions.
Is the Mac app free?
Yes. The free plan costs $0 with no credit card and no signup, and includes 15 free minutes every day, sessions up to 15 minutes and all four modes, including Mock Interview. Paid plans start at $14.99/mo on sale (regular $19.99).
Can I use it during a real interview on my Mac?
Follow the rules of the employer or assessment you're in — many people use it only to practice, which works on the free plan. Where live help is allowed, run the exact setup you tested the day before.
