Making the next Mac test useful

A downloadable app is only the start of a useful test. This preview adds Run client checks, Export report… and the matching mallow diagnostics command, so a report identifies its build, prerequisites and observed timings.

Devlog #0: Hello, Mallow

Mallow is a new open-source project with a simple goal: make it easy, and safe, to run Windows games and apps on Apple Silicon Macs. It builds on Wine, Rosetta 2 and DirectX-to-Metal translation, and it aims to be an open alternative to CodeWeavers' CrossOver.

First, the honest part. Mallow is pre-alpha and in the design phase. No application code exists yet, so there's nothing to download or try. This devlog is where we'll share how it goes, starting from zero.

Why Mallow is 0BSD

Mallow's own code, scripts and docs use the BSD Zero Clause License, or 0BSD. It's about as close to public domain as a licence gets. You can use Mallow for anything, commercial use included, change it, and redistribute it, and you don't even have to keep our name on it.

This post explains why we chose it, how it sits next to a Wine runtime that's LGPL, and what it means if you'd like to contribute.
