Adobe InDesign 21.6.0 — Mac build

InDesign 21.5.1 runs on both Apple silicon and Intel 64-bit Macs, as long as you're on macOS 13 Ventura or newer. That covers the current Mac lineup and most Intel models still in use. It's a page layout and desktop publishing app, so it's the tool for building multi-column documents, tables, and formatted text for print, web, or tablet output.

The standout features here are the ones that save time on repetitive work. Data Merge now handles multiline records and UTF-8 encoded data files, which matters if you're pulling in long text fields or non-Latin character sets. Bulk AI-generated Alt Text is also in — you can generate or remove it for multiple images at once, which is a real time-saver when prepping accessible PDFs or EPUBs.

Accessibility got attention in this release. Table accessibility improvements in PDF and EPUB exports mean screen readers will handle complex layouts better. There's also a keyboard shortcut search in the Keyboard Shortcuts dialog, so you can find the command you need without digging through menus.

The interface ships in 22 languages, including English, German, Spanish, French, Japanese, and Chinese. For layout work, this is a solid update.

A few things come up regularly with this version. The instructions cover the steps, and it's worth following them exactly. Mixing releases from different build groups when installing multiple Adobe apps can cause conflicts, so if you're also grabbing Photoshop or Illustrator from elsewhere, keep the builds consistent.

Second, the language setup. InDesign 21.5.1 ships with 22 languages in the interface — English, Russian, German, Arabic, Hungarian, Danish, Hebrew, Spanish, Italian, Traditional Chinese, Simplified Chinese, Korean, Dutch, Norwegian, Polish, Portuguese, Turkish, Ukrainian, Finnish, French, Czech, Swedish, and Japanese. The installer lets you pick, but if you need to switch later, the Language menu in Preferences handles that. The app doesn't require a restart for most language changes.

Third, disk space. The installer needs 4.5 GB free. That's just the base install — documents, fonts, and cache will add more over time. 8 GB of RAM is the stated minimum, and Metal support is required for optimal GPU performance. If your Mac has a dedicated GPU, make sure Metal is available in macOS settings. Intel Macs without Metal support will fall back to software rendering, which works but is slower on complex pages.

The app uses macOS system fonts by default, and you can install additional typefaces directly into the system font folder. It also reads OpenType, TrueType, and Type 1 fonts without extra configuration.

For output, the app exports to EPUB, PDF, and HTML natively. That PDF export respects macOS color management if you have ICC profiles set up. The EPUB export is useful for digital publishing workflows, and the HTML output works as a quick preview without needing the HTML Preview plugin in this version. Print workflows benefit from the table accessibility improvements — tagged PDFs export cleaner structures for screen readers.

The home screen now lets you add local files as cloud documents and download cloud documents. That bridges the gap between local work and Adobe's cloud storage, though you don't need an active connection for most tasks. The collaboration and review comments tools are built in, so multiple people can mark up a layout without leaving the app.

You open the app and land on the home screen. From there, you can start a new document from a preset or open a recent file. For a magazine layout, you'd set up facing pages, columns, and margins. The interface responds to keyboard shortcuts — if you forget one, the Keyboard Shortcuts dialog box in Edit > Keyboard Shortcuts now includes a search field. Type "table" and it filters to table-related commands immediately.

You place text and images into frames. For a data-heavy project like a catalog, you use Data Merge. You import a UTF-8 CSV file with multiline records — product descriptions that span two lines in the source. The Data Merge panel handles those without collapsing them. You preview the merged document, tweak the formatting, and generate the final output.

Before exporting to PDF, you run the AI-generated Alt Text tool. Select multiple images in the document, right-click, and choose to generate Alt Text in bulk. The descriptions come back in a few seconds. If they're not right, you can remove them in bulk and start over. Then you export to PDF with tagged table structures enabled. The output file passes accessibility checks in Acrobat.

If you're working with collaborators, you save the file as a cloud document from the home screen. That uploads it to Adobe's servers, and your editor can open it in InDesign and leave review comments. When the comments come back, you address them and download the updated cloud document back to local storage.

What changed in daily use with version 21.5.1

The table accessibility improvements in PDF and EPUB exports are the kind of change you notice when you run an accessibility check — the tables tag correctly as tables rather than flattened as generic containers. For anyone producing accessible documents for clients or institutions, that saves manual tagging time.

Keyboard shortcut search is a small quality-of-life change. Instead of remembering or guessing the shortcut for, say, fitting an image to a frame proportionally, you open the dialog and type "fit." It shows the matching shortcuts. No more hunting through menus.

Data Merge with multiline records and UTF-8 support removes a previous limitation. If you work with non-English data, or with fields that contain line breaks, you can now import those directly. No need to pre-process the CSV to strip line breaks or re-encode it to a different character set.

The HTML preview no longer requires the HTML Preview plugin. That plugin was separate before; now it's built in. If you export to HTML for web previews, the workflow is one step shorter.

Adding local files as cloud documents and downloading cloud documents from the home screen makes hybrid workflows smoother. You can start a project offline, then push it to the cloud when you're ready to share. Or grab a cloud document to work on during a commute without needing a constant connection.

The bulk AI-generated Alt Text feature is the biggest time-saver for accessibility. Before 21.5.1, you had to generate or edit Alt Text one image at a time. Now you can select a dozen images, generate descriptions for all of them, and remove them if needed. For a 40-page catalog, that cuts a repetitive task down to a few clicks.
