How to run Heartworm Demo on Mac with CrossOver

Good· Compatibility

Running Heartworm Demo through CrossOver translates its Windows DirectX calls into Metal on Apple Silicon — no reboot, no Windows license, no virtual machine. Most setup time is spent on first-time bottle configuration and installing the game launcher (Steam, Epic, etc.) inside CrossOver. Once that's done, launching feels close to native. Expect 15–30 minutes of setup on the first run.

Step-by-step

Step 1 — Create a bottle

  1. Open CrossOver → click New Bottle
  2. Name it after the game (e.g. Heartworm Demo) and choose Windows 10 64-bit
  3. Open the bottle's Settings and set:

- Graphics: D3DMetal (not DXVK)

- Synchronization: ESync

- High Resolution Mode: Off

Step 2 — Install the game launcher

  1. Inside CrossOver, click Install Application → search for Steam (or Epic Games Launcher if you own it there)
  2. Install it into the same bottle you just created
  3. Launch Steam, log in, and let it fully update before proceeding

Step 3 — Install and launch Heartworm Demo

  1. Open Steam (or your launcher) inside CrossOver
  2. Install Heartworm Demo through the launcher as normal
  3. Launch the game — use the launcher's Play button, not CrossOver directly
  4. First launch may take 30–90 seconds to show a window. Don't force-quit unless it hangs for several minutes.

Step 4 — If you hit issues

  • Black screen / stuck in small window: go to Settings → Graphics in-game, set Screen Type to Fullscreen, then restart
  • Resolution resets on every launch: find the game's config/settings file and set the resolution values manually, then mark the file Read-Only to prevent the game overwriting it
  • Crashes on startup: try switching the bottle's Synchronization from ESync to MSync, or vice versa

How to run Heartworm Demo on Mac with Parallels

Estimate· Compatibility

Using Parallels to play Heartworm Demo means running a full copy of Windows 11 ARM inside macOS. This is the most "it just works" approach for games that don't behave under CrossOver, and DirectX 11 is hardware-accelerated. You'll need a Windows license and roughly 80 GB of disk space.

Step-by-step

  1. Buy / start a trial of Parallels Desktop.
  2. Install Windows 11 ARM via the one-click wizard.
  3. Inside Windows, install Steam / Xbox app and Heartworm Demo.
  4. Enable DirectX 11 in Parallels settings for best 3D performance.
