LightBurn 2.0.05 Mac download

A shop in Columbus needed a consistent way to cut acrylic signs. The operator had a MacBook Air and a CO2 laser with a rotary axis. LightBurn on Mac handled the whole job: draw the shape, arrange the cut lines, and send it to the machine.

• Built-in vector editor for creating and editing shapes from scratch.
• Image tools like vectorization, masking, and edge enhancement for turning photos into cut paths.
• Boolean operations, offset, and weld for refining geometry without leaving the app.
• Rotary axis and camera support for engraving cylinders and aligning work precisely.
• Dark Mode and an improved Camera Calibration option in version 2.0.

LightBurn Mac covers hobbyists and professionals alike. For macOS 11 users, version 2.0.05 is the build to grab. It runs via Rosetta on Apple Silicon, so the M2 MacBook Air in my bag handles it fine.

Drag an SVG from Finder

I start with an SVG from the client. Drag it into LightBurn. The import dialog asks about scale and units — I leave it at mm. The shape lands on the workspace, and I open the Edit Nodes toolbar to clean up a few overlapping lines. The Weld tool merges them in one click.

Next I set the material. I open the material library, pick "3mm Acrylic Cast" from the list. The preset fills in power and speed for both cut and engrave layers. I bump the pass count to 2 because this piece is thick.

Positioning comes next. I use the alignment tools to center the shape on the bed. I check the camera view to see where the material sits. Calibration was set once months ago, so it's just a glance to confirm placement.

I send it over USB. LightBurn displays the job preview, showing every line's order and direction. I jog the head to a corner to confirm zero, then hit start. The laser runs the pass, and I can watch the estimated time count down. When it finishes, the part drops out clean.

That whole chain — import, edit, set material, position, send — stays inside LightBurn. No other program needed.

Set default units and Dark Mode first

After installing, open Preferences. The General tab has two things I change every time:

• Set default units to mm or inches depending on your stock.
• Enable Dark Mode under the Appearance section. It spares the eyes in a dim workshop.

Under Laser Settings, verify that the connection type matches your controller (GCode, DSP, or Galvo). The wrong type means no communication. I also set the home position to the front-left corner — it matches my machine's physical stops.

In the Rotary tab, if you run a cylinder jig, flip the jog direction to CW or CCW to match the motor. Version 2.0.05 fixed the CCW jogging bug, so that now works correctly.

Drop SVGs from Finder into the workspace

LightBurn works as a standalone app, but it integrates with macOS workflows in a few ways:

• File handling: drag SVGs or PDFs from Finder straight into the workspace. No import dialog needed unless you want scale control.
• Keyboard shortcuts follow Mac conventions: Cmd+C, Cmd+V, Cmd+Z. The Edit Nodes toolbar respects those too.
• The DMG install leaves LightBurn in Applications. It doesn't scatter files across the system. Uninstall is just a drag to Trash.
• Since it runs under Rosetta on Apple Silicon, it coexists with native apps. I keep Affinity Designer open alongside for heavy graphics work, then copy paths over as SVGs.

For a real-world mix: a client sends a PDF proof. I open it in Preview to check dimensions, then drop it into LightBurn for vectorization. The trace results need minor cleanup with the node tool. That job becomes a cut file in about five minutes.
