MetalHorizon 0.3.2 (prototype)

Prototype. MetalHorizon for Forza Horizon 6, on Apple silicon Macs.

New in 0.3.2

• Experimental Steam support. Point the game folder at your Steam install of Forza Horizon 6 (Steam
  installs ship steam_appid.txt) and MetalHorizon installs a second engine — Blackwell Engine's own series
  plus two of Highball's own patches, so a launcher's
  own window (Steam's included) draws instead of staying black — then downloads and installs Steam itself into
  a prefix of its own, and plays through Steam (steam.exe -applaunch), so the Steam client stays resident as
  Forza Horizon 6 on Steam expects. Not verified in game: this project has no Steam copy to test with.
  Signing in and installing the game in Steam's own window is your step, like Microsoft sign-in already is for
  the Xbox edition. Please report back if you try it.

From 0.3.1

• A welcome window on first launch, and ☕ Support Me (buymeacoffee.com/zaidalexandre).
• No CrossOver.app: the game runs on Blackwell Engine, MetalHorizon's own Wine, with Apple's D3DMetal 4.
• Everything installs by itself from blackwell-engine, checked by SHA-256.

Get started (Xbox / Microsoft Store edition)

1. Unzip MetalHorizon-0.3.2.zip and move MetalHorizon to Applications.
2. Not notarized yet: the first time, right-click it → Open → Open.
3. Accept Apple's licence when asked, then Sign In with Microsoft….
4. Choose a game folder with a short path (for example ~/FH6, not in iCloud Drive), click Download from Xbox (about 160 GB), then Play.
5. If macOS asks to let xodus-service use the "Xodus Service" Keychain item, choose Always Allow.

Get started (Steam edition, experimental)

1. Point the game folder at your Steam install of Forza Horizon 6.
2. Click Install Steam… next to "Steam client", click through Steam's own installer, then sign in.
3. Click Play: MetalHorizon launches Forza Horizon 6 through Steam.

Quit the game from its own menu; for the Xbox edition, wait about 30 seconds so the cloud save uploads.

Known

Frame pacing (short freezes), black near foliage, a crash while the map loads under heavy logging (Xbox
edition). Steam edition: untested beyond installation. Tested on one Mac (M5 Pro, 48 GB, macOS 27).

MetalHorizon 0.3.1 (prototype)

Prototype. MetalHorizon for Forza Horizon 6, Xbox / Microsoft Store edition, on Apple silicon Macs.

New in 0.3.1

• A welcome window on first launch: what MetalHorizon does by itself and the few steps that are yours.
• ☕ Support Me: opens buymeacoffee.com/zaidalexandre.

From 0.3.0

• No CrossOver.app any more. The game runs on Blackwell Engine, MetalHorizon's own Wine, with Apple's D3DMetal 4.
• Everything installs by itself. On first launch the app downloads Blackwell Engine and Apple's D3DMetal from blackwell-engine, checks their SHA-256, shows Apple's licence (D3DMetal installs only if you accept it) and sets up the DirectX 12 shim.
• AI assistant (MCP), plain macOS window (from 0.2).

Get started

1. Unzip MetalHorizon-0.3.1.zip and move MetalHorizon to Applications.
2. Not notarized yet: the first time, right-click it → Open → Open.
3. Accept Apple's licence when asked, then Sign In with Microsoft….
4. Choose a game folder with a short path (for example ~/FH6, not in iCloud Drive), click Download from Xbox (about 160 GB), then Play.
5. If macOS asks to let xodus-service use the "Xodus Service" Keychain item, choose Always Allow.

Quit the game from its own menu and wait about 30 seconds: the cloud save uploads as it closes.
