Mac document review checklist for Markdown and monitors

The short answer: before sending a Markdown draft, support note, release note, spec, article outline, or handoff document, freeze the source and audience, preview the Markdown locally, verify links and tables, make the monitor readable, and save one review note with the final decision.

This is for people who review text-heavy work on a Mac: product docs, internal briefs, customer-facing support notes, README drafts, changelog sections, acceptance criteria, launch copy, and technical handoff notes.

Disclosure: I build TeenyApps, including TeenyTool for local utility checks and TeenyDisplay for external monitor control. My bias is toward local Mac workflows. Finder, Preview, your editor, and macOS Displays settings are still the baseline.

If the source is a PDF, use the narrower Mac PDF review checklist. If the source is a CSV or dashboard, use the Mac data review checklist or dashboard QA checklist. This guide starts when the review target is a text document, often in Markdown.

Document review decision table

01Freeze the review target first

Start with the boring details. Write down the file name, owner, audience, deadline, source material, and the decision you are supposed to make. Are you approving the words, checking format, confirming links, or deciding whether the document can leave the company?

This step prevents two common failures. The first is reviewing an old draft because it was the last one in a chat thread. The second is editing a document without knowing whether the reviewer needed copy fixes, factual checks, formatting checks, or legal approval.

Use a plain folder when files are involved. Keep the source draft, any screenshots, exported previews, and final notes together. If the review turns into a file upload or client handoff, switch to the Mac file upload checklist before sending it.

02Preview Markdown before the draft spreads

Markdown is readable as plain text, but review happens in the rendered result. Check heading levels, bullets, numbered steps, task lists, links, tables, blockquotes, and code fences before the text lands in a ticket, docs system, README, CMS, or customer email.

TeenyTool includes Markdown Preview in its local Mac menu bar toolbox. Its Swift source parses block types for headings, paragraphs, bullets, ordered lists, task list items, tables, blockquotes, rules, and fenced code blocks. It uses Swift's AttributedString inline Markdown parsing for inline emphasis and links inside preview text.

For the focused local workflow, use the TeenyTool guide to Markdown preview on Mac for local document review. It keeps README drafts, release notes, support replies, docs tables, and private snippets in one review pass.

That is useful for a quick manual check. It is not a promise that every docs platform, Git host, or CMS will render every extension the same way. CommonMark exists because Markdown implementations have historically differed. Treat a local preview as a first pass, then check the real publishing system when the exact renderer matters.

03Keep private snippets out of throwaway web tools

Markdown drafts often include material that feels harmless because it is "just text": internal URLs, customer names, issue IDs, unreleased product copy, discount terms, code samples, support macros, migration notes, or legal caveats. The cleanup job can be small while the data is still sensitive.

Use local tools for local problems. Preview the Markdown locally. Clean copied text locally. Count words locally. Decode or format private snippets locally when a tool supports that job without sending the input to another service.

TeenyTool's homepage is explicit about the boundary: most tools run on the Mac, while license validation, update checks, IP Address, and DNS Lookup use the network. That makes it a good fit for local text, Markdown, JSON, URL, PDF, color, timer, and image checks. It is not the right tool when the work depends on live web facts.

04Make the monitor state serve the review

Long document review is harder when the external monitor is technically sharp but practically uncomfortable. Do not choose the display mode by resolution alone. Choose the state where headings, footnotes, tables, code blocks, comments, and side-by-side source material stay readable for the whole session.

Start in macOS Displays settings for arrangement, mirror or extend, resolution, refresh rate, brightness where available, and color profile. If a third-party display hides useful controls behind hardware buttons, TeenyDisplay can help after macOS sees the display.

TeenyDisplay's homepage and source confirm external monitor brightness, contrast, volume, input source, shortcuts, URL commands, software dimming fallback, resolution and refresh-rate handling, and presets. The preset source can save supported values such as brightness, contrast, volume, input, resolution, refresh rate, and HiDPI state against display identity. Use that for repeat review desks, not for random one-off setups.

For the review-specific monitor pass, use the TeenyDisplay guide to Mac external monitor setup for document review. It focuses on readable scaling, brightness, contrast, source windows, and a repeatable Review preset.

05Review links, tables, and code blocks separately

Do not review a Markdown document as one blob. Headings, links, tables, and code blocks fail in different ways. A good paragraph can sit under the wrong heading. A perfect table can be unreadable on the target width. A code block can wrap in a way that changes what the reader copies.

For links, check the visible anchor, destination, and whether the link should be internal, external, private, or public. For tables, check whether the columns survive the target viewport. For code blocks, check language labels, line wrapping, and whether the snippet includes secrets or machine-specific paths.

If the document will be shown live on a call or room display, run the Mac presentation display and audio checklist too. Document readability in your editor is not the same as document readability for someone across a room or screen share.

06Leave one boring handoff note

A reviewed document should not depend on memory. Save a short note beside the final draft or paste it into the ticket where the draft will be approved.

A useful review note includes:

1. Document file name, owner, and reviewed version.
2. Source status: current, stale, missing, or partially verified.
3. Renderer checked: local preview, docs system, Git host, CMS, or email.
4. Links checked, including private links that should not ship.
5. Tables, code blocks, screenshots, or other sections that need a second look.
6. Display setup used if readability or presentation mattered.
7. Decision: approved, approved with caveat, blocked, or needs source review.

The note can be short. It just needs to tell the next person what you actually reviewed.

Ten-minute Mac document review routine

1. Put the draft, sources, screenshots, and notes in one folder or ticket.
2. Write the reviewer, audience, and decision needed at the top of your note.
3. Preview Markdown locally before pasting it into a shared system.
4. Check headings, links, lists, task items, tables, and code blocks as separate passes.
5. Keep private snippets in local tools until they are safe to share.
6. Set a readable monitor layout before starting a long review.
7. Use the target renderer when exact Markdown behavior matters.
8. Save the final decision with the reviewed file name and source status.

Common questions

How should I review a Markdown document on Mac?

Freeze the source and audience first, preview the Markdown locally, check headings, links, tables, code blocks, and task lists, then send only the reviewed version and a short decision note.

When is an external monitor worth using for document review?

Use an external monitor when it lets you keep the draft, source material, and notes visible without constant window switching. It is worth it only if text stays readable at the chosen resolution and brightness.

Should private Markdown drafts go into web preview tools?

Avoid web preview tools for drafts that include private customer details, unreleased product copy, internal URLs, credentials, or legal notes. Keep those checks local until the text is safe to share.
