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.

Requirements: Apple Silicon Mac, macOS 14 or later. Self-contained — no Python or other setup needed.

Pathstitch 1.1.3

Pathstitch 1.1.3

Self-contained macOS app — no Python, conda, or repo install required. Apple Silicon (arm64), macOS 14+.

Smaller download

The bundle is ~17% smaller (DMG 464 MB → 383 MB; installed ~1.5 GB → ~1.1 GB) with no change to functionality:

• Native libraries are symbol-stripped (lossless) and re-signed.
• Proven-unused VTK components and package test suites removed.
• A built-in import smoke test of the full dependency closure gates every build, so a trim can never ship a broken runtime.

Also

• App and DXF refinements.
• Ships with Sparkle auto-update — existing installs will offer 1.1.3 in place.

Install

1. Open the DMG and drag Pathstitch onto Applications.
2. First launch: right-click the app ▸ Open to bypass Gatekeeper (ad-hoc signed, not notarized).

Pathstitch 1.1.0

Pathstitch 1.1.0

Install

The bundled Python backend is trimmed for a smaller download.

Pathstitch 1.0.0

First public build of Pathstitch — a native macOS CAD/CAM app for leathercraft & pattern making.

Install

1. Download Pathstitch-1.0.dmg below and open it.
2. Drag Pathstitch onto the Applications folder.
3. First launch is blocked by Gatekeeper (the app is ad-hoc signed, not Apple-notarized). To open it:
   System Settings ▸ Privacy & Security ▸ Open Anyway, then confirm.

Requirements

• Apple-Silicon Mac (M1 or newer), macOS 14 (Sonoma) or later. Tested on macOS 26.
• Self-contained — no Python/conda needed; the backend ships inside the app.

What's inside

• 2D sketching (line, circle, rectangle, text, pen) with snapping & on-creation dimensions
• Parametric fillet / chamfer (G1/G2, per-corner, drag-to-size, Enter confirms / Esc cancels)
• Trim tool (hover preview + click/drag), offset, stitch-hole generation
• Move/rotate/scale/mirror/duplicate, layers, convert-lines, patterning, paper-folding
• 3D STEP import + unfold to 2D nets
• DXF / SVG / PDF / PNG export, native .stch projects, Finder QuickLook & thumbnails
• Customizable keybinds, light/dark themes, ⌘K command palette, rearrangeable toolbar
