+| macOS (Intel) | `Skiller-<version>-macos-x64.dmg` | Signed + notarized. Same flow as the Apple Silicon build. |
 | Windows (x64) | `Skiller-<version>-win-x64.exe` | NSIS installer. SmartScreen may show a one-time warning — click "More info" → "Run anyway". |
 | Linux (x64) | `Skiller-<version>-linux-x86_64.AppImage`, `.deb`, or `.tar.xz` | AppImage: `chmod +x`, run — static squashfuse runtime, no `libfuse2` required (works on CachyOS/Manjaro/EndeavourOS out of the box). `.deb` for Ubuntu/Debian. `.tar.xz`: extract, `cd Skiller-*`, run `./install.sh` once (sets SUID on `chrome-sandbox`, registers a `.desktop` entry). Passing `--uninstall` to the same script removes the menu entry. |
