Important

macOS Usage

Because the macOS app is built and uses an ad-hoc signature, macOS Gatekeeper will quarantine the app and may display a *"Launch failed"* or *"App is damaged"* error upon first launch.

To bypass this protection, after extracting the file, open your **Terminal** and run the following command to clear the quarantine flag:

```
xattr -cr /path/to/CasioEmuMsvc.app
```

(Replace /path/to/CasioEmuMsvc.app with the actual path to your extracted app. You can type xattr -cr and drag the App into the Terminal window). After running this command, you can simply double-click the app to open it normally.
