When you first download and open PeachLeaf, macOS may display a security warning. This is normal for apps distributed outside the Mac App Store.

If you see "damaged" or "corrupted" error:

This happens because the app is not notarized by Apple. Use this command to bypass Gatekeeper:

# After copying app to Applications folder:
sudo xattr -rd com.apple.quarantine /Applications/PeachLeaf.app
sudo codesign --force --deep --sign - /Applications/PeachLeaf.app

Or disable Gatekeeper temporarily (not recommended):

sudo spctl --master-disable
# Open PeachLeaf.app once, then re-enable:
sudo spctl --master-enable

If you see "unidentified developer" warning:

Method 1: Right-click to open (Recommended)

1. Right-click (or Control-click) on PeachLeaf.app
2. Select "Open" from the menu
3. Click "Open" in the dialog that appears

Method 2: System Settings

1. Try to open PeachLeaf normally (it will be blocked)
2. Go to System Settings → Privacy & Security
3. Scroll down to find "PeachLeaf was blocked"
4. Click "Open Anyway"

Method 3: Terminal command

xattr -cr /Applications/PeachLeaf.app

After using any of these methods once, PeachLeaf will open normally in the future.

1. First Launch: A default note window will appear
2. New Note: Press ⌘N or select File → New Note from the menu
3. Start Typing: Click anywhere in the note to start editing

2. Drag any of the 8 resize handles (corners or edges)
3. The image will maintain its aspect ratio

• Click on an image to select it
• Press Delete or Backspace

1. Select Color → Choose Color... from the menu
2. Click on a color palette
3. The color picker will close automatically

All data is stored locally in your home directory:

~/.peach-leaf/
├── state.json                    # Window positions and settings
└── notes/
    ├── note-1234567890.md        # Note content
    └── images/
        └── note-1234567890/      # Images for this note
            ├── image-1234567891.png
            └── image-1234567892.png

Notes are stored as plain markdown files with optional width comments for images:

# My Note

Some text here.

![image](./images/note-1234567890/image-1234567891.png)<!-- width:600 -->
