MacOS Troubleshooting: How to run the game on Mac

Several macOS security or compatibility features can prevent the game from launching, especially on newer versions of macOS or on Apple Silicon machines.
This page lists the most common issues and how to fix them.

Quick Navigation

1. Older Macs Without Metal Support

First thing to verify is that your hardware is compatible with the game. Lucid Lust requires Metal, and all Macs from 2012 and later support Metal. If your Mac is very old and doesn't support Metal, there is unfortunately no fix. The hardware cannot run the game. This is similar to the transition from 32-bit to 64-bit on Windows: very old systems simply cannot run newer games.

2. "File is corrupted" Error

First, ensure your file is not an incomplete download; it should exactly match:

  • the DMG size for v0.5.6 Supporter: 7.747.754.930 bytes
  • the DMG size for v0.5.6 Public: 4.452.937.382 bytes

If the download is complete, some versions of macOS may still display an error because the app inside the DMG is not notarized by Apple. You might see an error message like:
"The disk image is corrupted and cannot be opened."

[Fix] Avoids the false "corrupted file" error.
  • Right-click the .dmg
  • Select Open
  • Confirm to continue (macOS should now show the correct prompt: "This app is from an unidentified developer.")
  • Confirm to continue
3. Won't Launch On Apple Silicon (M1-M6)

On an Apple Silicon Mac, macOS may refuse to launch it if Rosetta 2 is not installed.

[Fix] Install Rosetta 2.
  • Open Terminal and run:
softwareupdate --install-rosetta
  • Accept the terms when prompted
4. Browser Quarantine Attribute

Safari, Chrome, and other browsers can add a quarantine flag to downloaded files, which may trigger a warning or prevent the app from opening.

[Fix] Remove the quarantine attribute.
  • Open Terminal
  • Run:
xattr -c "/path/to/Lucid Lust.dmg"

You can also type xattr -c (with a space), and drag-and-drop the .dmg into the Terminal window to automatically insert the correct path.

5. "App is damaged and can't be opened" Error

This error typically appears on newer macOS versions when trying to open the app itself, even after following the steps above. This happens because the quarantine attribute may persist on the .app file inside the mounted .dmg.

[Fix A] Remove quarantine from the .app before launching.
  • Mount the .dmg file (double-click it)
  • Open Terminal
  • Run:
xattr -cr "/Volumes/Lucid Lust/Lucid Lust.app"

Note: Adjust the path if your .dmg has a different volume name. You can type xattr -cr followed by a space, then drag-and-drop the .app from the mounted volume into Terminal to auto-fill the path.

  • Try launching the app from the mounted volume
[Fix B] Copy to Applications folder first, then remove quarantine.
  • Mount the .dmg file
  • Copy "Lucid Lust.app" to your Applications folder or Desktop
  • Open Terminal
  • Run:
xattr -cr /Applications/Lucid\ Lust.app

(Or adjust the path if you copied it to Desktop or elsewhere)

  • Right-click the app and select Open
[Fix C] Verify the .dmg integrity.

If none of the above works, the download may genuinely be corrupted. Verify it by running:

hdiutil verify "/path/to/Lucid Lust.dmg"

If this reports errors, delete the .dmg and re-download it.

[Fix D] Temporarily disable Gatekeeper (last resort).

Warning: This reduces system security temporarily. Only use if all other methods fail.

  • Open Terminal
  • Run:
sudo spctl --master-disable
  • Enter your password when prompted
  • Try opening the app
  • Re-enable Gatekeeper immediately after by running:
sudo spctl --master-enable
6. Laggy Gameplay

If the game runs slowly, stutters, or your FPS drops significantly, it may be because your GPU or CPU cannot handle the current graphics.

[Fix] Adjust graphics settings.
  • On the main menu, click the gear icon to open the settings menu
  • Lower Hair Quality, Texture Quality, and Shadow Resolution to Medium, while keeping other settings green if possible

These adjustments can significantly improve performance on older or less powerful hardware without affecting the core gameplay experience. After trying the game with these settings, if it works fine, you can stop there and enjoy Lucid Lust!
If the game is still laggy, try more aggressive settings adjustments:

  • Lower all Quality sliders and Shadows sliders to Lowest/None
  • Disable SSAO, SSR, SSS, and other post-processing effects

It is still highly advised to keep Eyes Depth active, as this is a core component of the eyes' appearance.
If the game is still laggy, you can go further by editing advanced game settings.
