When users update macOS to Catalina, there is potential conflict between mksqlite and the upgraded system. Users may experience error when calling `RSKopen`. We suggested below steps to solve this:
- On your Mac, choose Apple menu
> System Preferences, click Security & Privacy, then click General.
- Click the lock icon to unlock it, then enter an administrator name and password.
- Select the sources from which you’ll allow software to be installed.
Now when you rerun `RSKopen`, you will be allowed to select open when the warning appears, which permits the use of the mksqlite toolbox.
