Installation and First-Time Setup

Install Notomo

System requirement: macOS 15 or later.

Download the latest DMG from notomo.app, open it, and drag Notomo into the Applications folder.

You can also use Homebrew:

brew install --cask notomo

Move to official Homebrew

Notomo is now in the official Homebrew repository. If you installed it from the natsustan/notomo tap, switch to the official cask. Uninstalling without --zap keeps your settings and license:

brew uninstall --cask notomo
brew untap natsustan/notomo
brew untrust natsustan/notomo
brew install --cask notomo

If you installed from the DMG and want Homebrew to manage Notomo, quit Notomo, move it from Applications to the Trash in Finder, then run:

brew install --cask notomo

Your settings and license are kept. If Notomo asks for Accessibility permission again after reopening, turn it back on in System Settings.

Either way, future releases arrive through Notomo’s in-app updates.

Complete first-time setup

1. Launch Notomo, then open Apple Notes.
2. Grant Accessibility permission when prompted.
3. To use Quick Open, Templates, Skills, and note links, grant access to the Apple Notes database folder.
4. The first time macOS asks, allow Notomo to access Apple Notes through Apple Events.
5. Click the Apple Notes editor, then try typing # or pressing ⌘K.

Why permissions are needed

Accessibility locates the cursor and reads selections. Apple Events reads the current note and performs formatting actions. Notomo does not copy your notes library into its own database.

Confirm that Notomo is ready

Start a new line in Apple Notes and type # . If the line changes to the Title style, Notomo is working.

If nothing happens, open Notomo → Settings → General, check the Accessibility status, and click the Apple Notes editor again.
