Requirements

• Apple Silicon or Intel Mac

Installation

About notarization: DodoPulse is not currently notarized by Apple. Notarization is Apple's security process that scans apps for malware before distribution. Without it, macOS may show warnings like "app is damaged" or "can't be opened". This is safe to bypass for open-source apps like DodoPulse where you can inspect the code yourself. Fix: Run xattr -cr /Applications/DodoPulse.app in Terminal, then open the app. Notarization is planned for a future release.

Option 1: Homebrew (recommended)

brew tap dodoapps/tap
brew install --cask dodopulse

On first launch, right-click the app → Open → confirm. Or run: xattr -cr /Applications/DodoPulse.app

Option 2: Download DMG

1. Download the latest DMG from Releases
2. Open the DMG and drag DodoPulse to Applications
3. On first launch, right-click → Open → confirm (see note above about notarization)

Option 3: Build from source

1. Clone the repository:

   git clone https://github.com/dodoapps/dodopulse.git
   cd dodopulse

2. Build the app:

   swiftc -O -o DodoPulse DodoPulse.swift -framework Cocoa -framework IOKit -framework Metal

3. Run:

   ./DodoPulse

Option 4: Create an app bundle (optional)

If you want DodoPulse to appear as a proper macOS app:

1. Create the app structure:

   mkdir -p DodoPulse.app/Contents/MacOS
   cp DodoPulse DodoPulse.app/Contents/MacOS/

2. Create DodoPulse.app/Contents/Info.plist:

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
   <plist version="1.0">
   <dict>
       <key>CFBundleExecutable</key>
       <string>DodoPulse</string>
       <key>CFBundleIdentifier</key>
       <string>com.bluewave.dodopulse</string>
       <key>CFBundleName</key>
       <string>DodoPulse</string>
       <key>CFBundleVersion</key>
       <string>1.0</string>
       <key>LSMinimumSystemVersion</key>
       <string>12.0</string>
       <key>LSUIElement</key>
       <true/>
   </dict>
   </plist>

3. Move to Applications (optional):

   mv DodoPulse.app /Applications/

Option 5: Run with Automator

This method allows DodoPulse to run independently of Terminal, so it keeps running even after you close Terminal.

1. Build DodoPulse first (see Option 1 above)

2. Open Automator (search for it in Spotlight)

3. Click New Document and select Application

4. In the search bar, type "Run Shell Script" and drag it to the workflow area

5. Replace the default text with the full path to your DodoPulse binary:

   /path/to/dodopulse/DodoPulse

   For example, if you cloned to your home folder:

   ~/dodopulse/DodoPulse

6. Go to File > Save and save it as "DodoPulse" in your Applications folder

7. Double-click the saved Automator app to run DodoPulse

Tip: You can add DodoPulse to your Login Items to start automatically at boot:

1. Open System Settings > General > Login Items
2. Click + and select your DodoPulse Automator app

Usage

Once running, DodoPulse appears in your menu bar showing CPU and memory usage.

• Left-click the menu bar item to open the detailed panel
• Right-click for a quick menu with settings, language selection, and quit option
• Click a card to open the related system app

Changing language

1. Right-click the DodoPulse icon in the menu bar
2. Select Language from the menu
3. Choose your preferred language from the submenu
