DRIG macOS Apple Silicon preview (2026-11-12)

Native macOS preview for Apple Silicon, built from main at 7666a0d6 plus the Metal fix in 67e91f29. The track material now packs its shader parameters into one uniform buffer, preventing a vertex buffer slot collision on Metal.

This snapshot also includes the recent AI, track rendering, drift and front-end changes from main.

Copy DRIG.app from the DMG to Applications or another local folder. The image includes the engine and DRIG icon. On first launch, select your own complete Windows GRID 2008 installation folder for the game resources.

The app is ad-hoc signed and has no Apple notarization. Verify the DMG using SHA256SUMS.txt.

Validated on Apple M4 with macOS 15.7.7. Donington reached 300 ticks with 11 opponents in windowed and offscreen runs, and a solo night run at Haruna reached 300 ticks. Bevy logged nonfatal mesh allocator errors. The public image passed signature, checksum and contents checks.

DRIG macOS Apple Silicon — engine-only preview (2026-11-02)

Native Apple Silicon macOS preview built from main 7dd7089e628d55a7d45c1a0642b554edfd3197d8 (Rust 1.99.0). Includes the DRIG app icon.

Copy DRIG.app from the DMG to Applications or another writable folder before opening it. This public download contains only the independent engine, not original GRID resources. On first launch select your complete purchased Windows GRID 2008 installation folder. On this Mac, resources retained in the private portable DMG can also be used after copying its app out and selecting DRIG.app/Contents/Resources/Grid.

Apple Silicon only. The app is ad-hoc signed, not notarized by Apple. This is an experimental preview, not a compatibility or performance guarantee.

The one-click rebuild script and packaging source are published in #15 (branch codex/macos-rebuild-release). Run Rebuild GRID.command --code-only for a public engine-only image, or supply --game-root for a private portable image. The engine is built from a frozen fresh main; packaging comes from the script checkout.

Checksums are supplied alongside the DMG. Build provenance is included in DRIG.app/Contents/Resources/build.json.

Validation: native release build; signed DMG verified; exact file whitelist excludes game assets; packaged executable --help passed.
Native Metal race smoke test passed: 300 ticks, 11 opponents, exit 0, rendered frame inspected. Test resources were read from a separate private image and are absent from the public download.

DRIG macOS Apple Silicon — engine-only preview (2026-10-29)

Experimental native Apple Silicon build of DRIG, the independent Rust/Bevy engine for Race Driver: GRID (2008).

No original GRID game data is included. You need your own purchased Windows GRID 2008 installation.

Install and play

1. Download DRIG-macos-arm64-preview-2026-10-29.dmg.
2. Copy DRIG.app to Applications or another local folder.
3. Launch the app and select your complete Windows GRID folder, containing grid.exe and cars.

The game folder stays in place. grid.exe is read for parameter data, not executed. Settings and logs are stored in ~/Library/Application Support/GRID Reassembly. To choose a different game folder, remove game-root.txt from that directory and launch again.

Scope and limitations

• Native arm64 / Apple Silicon. Tested on Apple M4 with macOS 15.7.7 and Metal; Intel builds are not provided.
• Ad-hoc signed, not notarized by Apple. macOS may require explicit user approval to open downloaded software.
• Preview quality: menu-to-race and a 12-car Donington render were checked. Feature gaps and significant slowdowns in smoke-heavy scenes remain. This is not a complete or performance-certified recreation.
• No NVIDIA/DLAA build features are enabled.

Engine source: fac75955722d03329110b3475dc53f250d6b00c4.

The packaging-source ZIP contains the macOS launcher/build helper, generated DRIG icon and release resource notices. It is an overlay for the engine source checkout, not a second copy of the game. SHA-256 checksums are provided for both downloadable files. Project, font and third-party license notices are included inside the app.
