How to install Pathstitch on a Mac

  2. Search for Pathstitch and press Get. OpenDMG downloads version 1.1.5 from Mason363's own GitHub release.
  3. Open it. The download is checked against its SHA-256 fingerprint and its signature is checked on your Mac before it lands in Applications.

What is new in Pathstitch 1.1.5

## Installing Pathstitch

### 1. Install
1. Download **Pathstitch-1.1.5.dmg** below and open it.
2. Drag the **Pathstitch** icon onto the **Applications** folder.
3. Eject the disk image and open Pathstitch from your Applications folder. You may also uninstall the .dmg from your **Downloads** folder.

### 2. First launch — allow it to open
The first time, macOS will say Pathstitch *"cannot be opened because Apple cannot check it for malicious software."* This is expected for any non-notarized app. Pick the path for your macOS version:

**macOS Sonoma (14):**
- **Right-click** (or Control-click) the Pathstitch app → **Open** → in the dialog, click **Open** again.

**macOS Sequoia (15) and later:**
1. Double-click Pathstitch once (you'll see the warning) and click **Done**.
2. Open **System Settings → Privacy & Security**.
3. Scroll to the **Security** section — you'll see *"Pathstitch was blocked…"* — click **Open Anyway**, then confirm with Touch ID / your password.

You only do this **once**. After that, Pathstitch opens normally every time, and future updates install automatically via the in-app updater.

Is it safe? Yes, completely. The app is 100% open-source, so the entire source code is public and auditable. The only reason it isn’t officially 'notarized' is because Apple charges a $99/year fee to maintain a developer account, which this free project doesn't have yet.
