Installing Pathstitch
1. Install
- Download Pathstitch-1.1.5.dmg below and open it.
- Drag the Pathstitch icon onto the Applications folder.
- 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:
- Double-click Pathstitch once (you'll see the warning) and click Done.
- Open System Settings → Privacy & Security.
- 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.
Requirements: Apple Silicon Mac, macOS 14 or later. Self-contained — no Python or other setup needed.
