How to Clean Up Your Mac Before a Job Interview Screen Share

It’s 9:53 AM. Your interview starts at 10. You’re going to share your screen at some point — they want to see your portfolio, your code, a live demo, something. You glance at your Desktop. There are 47 files on it. Three of them are screenshots called “Screen Shot 2025-11-03 at 11.48.32 AM.png.” One is a meme called dog-in-a-suit.jpg. Your Dock has Discord and Spotify and that game you uninstalled but the icon is still there for some reason.

Don’t go into the interview like this. Fifteen minutes of cleanup turns your laptop from “lived in” to “professional.”

Why this matters more than you think

Interviewers form impressions on micro signals you don’t notice. A screen full of clutter, weird app names, embarrassing notifications popping up mid-call, or a Slack message from your friend that says something inappropriate — these add up to “this person is sloppy” without the interviewer even consciously processing it.

The opposite is also true. A clean desktop, organized Dock, and zero notification interruptions reads as “this person has their stuff together.” It’s not the deciding factor, but it’s a free win.

Step 1: Notifications off, hard

Before anything else, kill notifications. The single biggest interview disaster is a Messages or iMessage notification with content nobody should see in a professional context.

System Settings > Focus > Do Not Disturb. Turn it on. Or:

• Hold Option and click the Date in the menu bar — instant DND toggle
• Or Control Center > Focus > Do Not Disturb

Verify by opening a notification-heavy app (Mail, Messages) and checking that no banners are appearing. While you’re at it:

• Quit Messages
• Quit Slack (or sign out of personal workspaces)
• Quit Mail
• Quit any chat app you don’t need for the interview

If the interview platform is Zoom, also enable Zoom’s “Do not disturb during meeting” setting in their Notifications preferences.

Step 2: Desktop, decluttered

Move every file off your Desktop. Don’t think about it. Just move them.

Make a folder called Desktop-Triage-2026-02-10 in Documents. Cmd+A on the Desktop, drag the whole pile into the new folder. Now your Desktop is empty. Done in 30 seconds.

You’ll triage the folder later. Right now, all that matters is the clean visual when you screen share.

If you genuinely use Desktop Stacks (View > Use Stacks), they auto-group files into tidy piles. Better than chaos but a clean Desktop is still better than tidy stacks during an interview.

Step 3: Wallpaper check

Look at your Desktop wallpaper. Is it:

• A photo of you and your partner in beachwear
• A meme
• A screenshot from a video game
• Something with text or symbols that could read weirdly out of context

Change it. System Settings > Wallpaper. Pick something neutral — one of the macOS defaults, a clean color, a landscape. The Sequoia and Sonoma defaults are all fine.

Two minutes of effort, removes a real risk.

Step 4: Dock cleanup

Your Dock is a window into your personality. Maybe more than your Desktop, since your Dock is visible most of the time during a screen share.

Right-click each app you don’t want visible. “Options” > “Remove from Dock” for the ones that are pinned. Or quit and they’ll disappear (for unpinned ones).

Hide:

• Personal chat apps (Discord, Telegram, WhatsApp)
• Spotify, Apple Music
• Games (Steam, Epic, anything that screams gaming)
• Random utilities you don’t need today
• That app called “OnlyFans Downloader” your friend installed as a joke

Keep:

• Browser
• The interview platform (Zoom, Teams, Google Meet)
• The portfolio app you’ll demo (Figma, VS Code, Notion, etc.)
• Standard system apps (Mail, Calendar, Settings) if you’ll need them

A minimal, professional Dock takes 2 minutes to set up.

Step 5: Browser, sanitized

If you’re sharing your browser, the tab list is visible. So is your bookmarks bar. So are autocomplete suggestions in the URL bar. So is your active profile picture.

Open a fresh, dedicated profile. Chrome, Firefox, and Safari all support multiple profiles. Make a profile called Interview. It has no history, no bookmarks, no signed-in accounts. Use it for the interview only.

If you can’t make a new profile in time, at least:

• Close all tabs except the ones you need
• Don’t type into the URL bar (autocomplete will reveal your history)
• Use Incognito/Private mode for any live demo browsing

Bookmarks bar. If you have a bookmarks bar visible in your normal browser, audit it. Remove or hide anything personal. Right-click the bar > Hide Bookmarks Bar if you can’t quickly clean it.

Profile picture. Some browsers show your Google account avatar in the corner. If yours is unprofessional, sign out or use a different profile.

Step 6: Disk space and performance

A laggy screen share is a bad screen share. Make sure your Mac isn’t thrashing.

Open Activity Monitor (Cmd+Space, type Activity Monitor). Click the Memory tab. Memory Pressure should be green. If it’s yellow or red, quit memory-heavy apps you don’t need.

Click CPU tab. Anything pegging the CPU? Quit it.

Check storage. Apple menu > About This Mac > More Info > Storage Settings. If you’re below 20 GB free, your Mac is going to feel sluggish during the call. Run a quick cleanup if you have time:

Step 7: The screen share dry run

Five minutes before the interview, do a dry run.

1. Open the interview app (Zoom, Meet, Teams)
2. Start a test screen share — share your screen to nobody, just to see what would be visible
3. Open the apps you’ll demo
4. Switch between them and watch what’s visible

Look for:

• Any window with personal info you forgot about
• Background apps that pop up (auto-update prompts, low battery, etc.)
• Anything in the menu bar that’s distracting (weather widget showing your home city, Slack with notification dot, etc.)

If your menu bar is cluttered, hide some items. macOS lets you Cmd-drag menu bar items off, or use a tool like Bartender to organize them.

Step 8: Charge and audio check

Plug in your Mac. A low-battery notification mid-interview is awkward and a bad signal. If the battery is below 50%, definitely plug in.

Test audio:

• Open the interview app
• Join a test call (Zoom and Teams have one built in)
• Verify your microphone and speakers
• Try AirPods and built-in mic, decide which sounds better
• Make sure the right input/output is selected in System Settings > Sound

Lighting check while you’re at it. Open Photo Booth. Look at the preview. If you look like you’re in a cave, move toward a window or turn on a lamp.

Step 9: Have a clean reference doc ready

You might want to share notes during the interview — talking points, questions for them, your portfolio link list.

Open a clean Notes window or a Pages doc with just the relevant content. Have it ready in a separate space (Mission Control > add a new desktop) so you can switch with Control+Right Arrow without flashing your other windows.

Spaces tip: Set up two desktops:

• Desktop 1: Interview app, browser with portfolio, demo app
• Desktop 2: Notes, references, anything for your eyes only

Switch between them with Control+arrow keys. Clean separation, no risk of accidentally screen-sharing private notes.

Step 10: One last paranoid pass

Two minutes before the interview, a final scan:

• Quit everything you don’t need
• Confirm Do Not Disturb is on
• Confirm wallpaper is fine
• Confirm Desktop is clean
• Confirm browser is on the right profile
• Confirm Dock is clean
• Notifications silenced on phone too (your phone notifications can be heard if your mic is on)
• Camera angle and lighting check
• Glass of water in reach

Then, deep breath. Open the interview link 30 seconds early.

After the interview

Whatever happens, take 10 minutes after to triage that Desktop-Triage-2026-02-10 folder. Move keepers to proper folders, dump the rest. Otherwise it just becomes another mess you have to deal with next time.

Also: keep your Interview browser profile around. Next interview, you’ve got a clean profile ready.

The whole pre-interview cleanup is 15 minutes the first time. Once you’ve done it once, it’s 5 minutes — you’ve already changed the wallpaper, you’ve already got the browser profile, you’ve already got the Spaces setup. The system pays you back forever.

Good luck. Clean screen, clear answers.
