Each region keeps its own game files. Regions of one publisher share one Wine prefix: the Windows environment with sign-ins, settings, and caches.
Where files live#
Paths start with ~/Library/Application Support/com.lumisxh.arknights-client/ unless noted.
| What | Location |
|---|---|
| Yostar games and prefix | Yostar/Global, Yostar/Japan, Yostar/Korea, Yostar/Prefix |
| Gryphline game and prefix | Gryphline/Taiwan, Gryphline/Prefix |
| Hypergryph games and prefix | Hypergryph/China, Hypergryph/China-Bilibili, Hypergryph/Prefix |
| Custom icons | Artwork/Custom |
| Playtime statistics | playtime-v1.json (local only, never uploaded) |
| Caches | ~/Library/Caches/com.lumisxh.arknights-client/ |
| Logs | ~/Library/Logs/com.lumisxh.arknights-client/ |
A custom installation location replaces only the game folder of that region. Settings → Storage shows the space each part uses. macOS backups exclude game folders and prefixes.
Logs#
Settings → Storage → Show Logs opens the log folder.

What cleanup removes#
| Action | Removes | Keeps |
|---|---|---|
| Clear Caches | Graphics and sign-in window caches (the next start is slower) | Games, sign-ins, settings |
| Rebuild… | Nothing; reruns the Windows environment setup on the next start | Everything |
| Delete Environment… | The publisher's prefix, including sign-ins and Windows settings | All game files and launcher settings |
| Reset All Settings… | Launcher preferences and launch options | Region, installation locations, game files |
| Reset Statistics… | Playtime totals | Everything else |
| Uninstall Game… | The game folder of the selected region (moved to the Trash) | Other regions, the prefix, the launcher |
Try Clear Caches and Rebuild… before Delete Environment….
Uninstall completely#
- Choose Uninstall Game… for each installed region.
- Choose Delete Environment… for each publisher you used.
- Quit the launcher and move Arknights Client.app to the Trash.
- Optional: Delete the folders in Where files live.
Removing only the app keeps game files, prefixes, caches, and logs.
After a launcher update#
Some updates rename the standard game folders to a new layout on the first start. Nothing downloads again. Custom locations are never touched.
If the launcher reports a conflict, do not delete or merge either folder. Report the problem with the launcher message.
