Hadron 0.1.1

A small release with one fix.

Fixed: games freezing for seconds when they start a thread. On macOS, Wine looked for free address space by trying every 64 KiB of a region the system had already mapped, while holding a lock every other thread needs. In Astroneer that froze the game for almost three seconds on finishing a mission. Wine now skips such a region in one step. Found, fixed and tested by @Footkick72 in #38, the first outside contribution to Hadron.

Updating from 0.1.0: install this version over the old one (brew upgrade --cask hadron, or replace the app from the disk image), then open Hadron and click Repair.

New here? Hadron is a compatibility tool that lets the native Mac Steam client install and run Windows games on Apple Silicon. It needs macOS 27 and Steam for Mac.

brew install --cask broyojo/hadron/hadron

or download Hadron-0.1.1.dmg below, drag Hadron to Applications, open it and choose Set up Steam. The README has the steps, and the list of games tried says what runs.

Setting up modifies and re-signs Steam.app; Uninstall in Hadron undoes it. Hadron is unofficial and not affiliated with Valve.
