Mac app demo checklist for client reviews

The short answer: run the demo once, save the exact UI evidence you may need, check system load before anyone joins, and keep Apple settings close for permissions, display, and audio. Do that before the meeting. During the review, keep the Mac quiet.

This is not a broad "clean your Mac" ritual. It is a client-demo checklist for app makers, designers, front-end developers, and indie teams who need a Mac to show a real product without losing ten minutes to permissions, noisy fans, wrong colors, or a bad output device.

Disclosure: I build TeenyApps, including TeenyColor and TeenyStat. My bias is toward small native Mac utilities. Apple's tools still own the deep checks.

Quick checklist

01Decide what the demo must prove

A client review goes sideways when the demo tries to be the whole product tour. Pick the one path that matters: sign in, edit a record, preview a screen, export a file, approve a color state, or compare a before-and-after build.

Then remove the avoidable branches. Close test data that does not matter. Put the right account, browser, simulator, device, or local build in place. If the review is about visual approval, open the exact screens and states that need a decision. If it is about performance, start from the same workload you will show on the call.

Write the fallback next to the path. A saved screenshot set is not as good as a live product, but it is better than asking five people to wait while you search Finder.

02Save the colors you may need to defend

Color debates are easier when you have values, not vibes. If the review may touch brand colors, dark mode, hover states, or accessibility fixes, sample the rendered UI before the call and name the colors by role.

TeenyColor fits that job because it samples screen colors with Apple's color sampler, copies the chosen format, keeps local color history, lets you rename and pin saved colors, and can export pinned or full palettes as text or JSON. Its source stores the color values, names, pin state, and timestamps locally in user defaults.

Use a small rule. Pin only colors you may discuss: primary button, destructive state, selected row, focus ring, dark background, disabled text. Leave random samples unpinned, or the review palette becomes another mess to explain.

For the exact prep pass, read save brand colors on Mac with pinned swatches. For broader color workflow context, use Mac color picker history and check dark mode colors from screenshots.

03Take a system baseline before anyone joins

A demo Mac does not need to be idle. It needs to be predictable. Watch the system for a minute before the meeting so you know whether CPU, memory, or fan speed is already outside your normal range.

TeenyStat is useful here because it keeps CPU usage, memory usage, and fan speed glanceable from the menu bar and popover. Its source reads CPU with host_processor_info, memory with host_statistics64, fan data through Apple SMC keys when fans exist, and keeps 60-point sparkline buffers plus session high and low values.

The boundary matters. TeenyStat tells you that the Mac is working harder than expected. It does not name the bad process. If CPU stays high, memory pressure is suspicious, or the fan trend makes no sense, open Activity Monitor before the client arrives and fix the cause there.

The exact prep pass is Mac demo performance baseline: CPU and memory. The TeenyStat guide Mac menu bar CPU monitor vs Activity Monitor covers the broader first-pass split.

04Check screen recording and privacy prompts

Screen sharing failure is usually boring: the browser, meeting app, demo app, or recording tool lacks permission. Apple's privacy settings are the source of truth. Review screen and system audio recording access in System Settings before the call, especially after app updates or a new browser install.

Do the same for any app that samples the screen. Apple's permission model is the right tradeoff, but it means a first launch can interrupt the review. TeenyColor surfaces a screen-access alert if macOS does not allow sampling. You still need to grant the permission in macOS.

Never test this by opening private client material in a random online tool. If a color, screenshot, log, or customer record is not meant to leave the Mac, keep the check local or use sanitized sample data.

05Keep display and audio boring

Display and audio deserve their own pass, but they should not dominate every app demo. Confirm the display mode, resolution, refresh rate, color profile, sound output, mic state, app volume, and alert volume before the review.

If the demo depends on a conference-room display, an external monitor, or a recorded walkthrough, use the detailed Mac presentation checklist for display and audio. That article goes deeper on monitor controls, output devices, and per-app sound. If the deliverable is a tutorial or saved walkthrough, use the Mac screen recording setup to stage copied commands, source links, app audio, and the final test take.

For a normal client review, keep it smaller: one known display state, one known input, one known output, one mute path, and one backup if the room hardware does something weird.

Fifteen-minute demo prep

1. Open the exact screen or workflow the client needs to review.
2. Save a fallback screenshot or short local recording of the same path.
3. Pin and name the UI colors that may come up in the review.
4. Check CPU, memory, and fan trend before the meeting app starts.
5. Open Activity Monitor only if the baseline is already abnormal.
6. Confirm screen recording permission for the meeting or recording app.
7. Confirm display, sound output, mic mute, and app audio.
8. Close anything that can generate a notification, sound, or private preview.

FAQ

What should I check before a Mac app client demo?

Check the exact demo path, saved color references, CPU and memory baseline, screen recording permission, display state, audio output, and one fallback for each likely failure.

Should I use Activity Monitor during a client demo?

Usually no. Use Activity Monitor before the demo or only if you need process-level diagnosis. A menu bar system monitor is better for a quiet first-pass signal during the review.

Can a local color picker help in a demo?

Yes, when the review includes rendered UI colors. Save important swatches before the call, then sample locally only when a live question needs a precise value.
