The opportunity

Great players are already on Mac. Too many great games aren't.

We believe Mac is gaming's most overlooked premium audience. Portborn closes the gap between PC games players already love and the Mac owners waiting to play them.

For developers, that means a new platform and a new revenue stream—without building an internal Mac team.

The Portborn process

From source code to a store-ready Mac release.

One partner across engineering, quality, submission, and launch.

01

Assess

We review the codebase, engine, dependencies, controls, and commercial fit before anyone commits.

02

Port

We adapt the build for modern macOS and Apple silicon, replacing platform-specific systems where needed.

03

Polish

We tune input, display, saves, performance, signing, sandboxing, and the details Mac players notice.

04

Publish

We package, submit, and support the launch—on the Mac App Store and wherever else makes sense.

Built for developers

A new audience. Without becoming a Mac studio.

Portborn is the specialist team you do not need to hire. We work from your existing source, protect what makes the game special, and structure the partnership around shared upside.

Start a confidential conversation
01

Your IP stays yours

Permission-based partnerships with clear ownership and boundaries.

02

Aligned economics

Flexible fee and revenue-share structures built around the opportunity.

03

Native means native

A real macOS product—not a compatibility wrapper presented as a port.

04

One accountable partner

Engineering, QA, store operations, launch support, and updates.

Proof, then promises

We started by making one run.

Our technical pilot uses Micropolis to exercise the path from an open-source PC codebase to a modern native macOS build.
