How to Enable Dark Mode in Word 2021 for Mac
Product
Microsoft Word 2021
Device & OS
macOS
Scenario
Adjusting the visual theme of the Word application to a dark appearance to reduce eye strain.
Observed behavior
Word for Mac does not offer an independent application-level Dark Mode toggle; its appearance is completely tied to the macOS system-wide appearance settings.
Before you start

Ensure your macOS is updated to a version that supports system-wide Dark Mode (macOS Mojave 10.14 or later) and save any open documents, as you may need to restart the application.

Solution 1Recommended

Change macOS System Appearance to Dark

Since Word 2021 for Mac relies on the operating system's settings, you must enable Dark Mode globally through your Mac's System Settings.

Unlike the Windows version of Microsoft Word, Word for Mac does not include a dedicated toggle to turn Dark Mode on or off independently. Instead, it listens to the macOS system appearance preferences and automatically adjusts its interface to match.

1
Open System Settings

Click the Apple logo in the top-left corner of your menu bar and select 'System Settings' (or 'System Preferences' on older macOS versions).

2
Navigate to Appearance

In the left sidebar, click on 'Appearance' to access your system theme controls.

3
Select Dark Mode

Choose the 'Dark' option at the top of the menu. You can also select 'Auto' if you want your Mac (and Word) to switch to Dark Mode automatically based on the time of day.

4
Restart Microsoft Word

If Word 2021 was already running while you made this change, completely quit the application (Cmd + Q) and reopen it to ensure the new dark theme is fully applied.

Change macOS System Appearance to Dark
System-Wide Change: Keep in mind that selecting 'Dark' in macOS System Settings will change the appearance of your entire operating system and all other compatible applications, not just Microsoft Word.

Frequently Asked Questions

Can I enable Dark Mode in Word for Mac without changing my entire Mac theme?

No, Word 2021 for Mac relies entirely on the macOS system settings. There is no independent built-in setting to toggle Dark Mode exclusively for the Word application.

Why didn't Word switch to Dark Mode after I changed my macOS settings?

If Microsoft Word was already open when you modified the macOS Appearance settings, the interface might not update immediately. You need to completely quit the application and restart Word for the changes to take effect.

How do I keep the document page white while using Dark Mode in Word for Mac?

If you want the application ribbons to be dark but prefer typing on a traditional white canvas, open Word, go to the menu bar, select Word > Preferences > General, and check the option for 'Dark Mode has a white page color'.
