macOS app development

Mac apps are their own job.

Not an iPhone layout on a bigger screen. Mac-first behaviour, AppKit when it is the right tool, and App Store work from someone who has done it for years.

Clients hire me when they need a Mac developer who already knows the platform’s corners: windows, menus, sandboxing, signing, notarisation, and the way Mac users expect software to behave.

I build new macOS apps, extend existing ones, and give high-quality technical advice when the next decision is expensive. If the App Store is part of the problem, we treat it as part of the work.

A good fit if

  • You need a real Mac app, not a wrapped website.
  • You want App Store or distribution help from someone who has been in that queue.
  • You need a technical counterpart who will say no when the idea is the wrong size.
