Microsoft is now rolling out dark mode to OneNote Insiders on the Mac. Dark mode is easier on the eyes in low-light environments. It is important to note that this dark mode feature requires macOS Mojave. Here’s how you can enable Dark Mode in macOS Mojave.
- Click the Apple icon in the upper left corner of the Menu Bar.
- Select System Preferences-> General.
- Select Dark Mode in the Appearances section.
You can download the updated OneNote app here from Apple App Store.
