Unusable on MacOS - Can't open

It's hard to use on MacOS X, the developer isn't recognized (installed it from the App Store, though) and every time I close the file I can't open it without authorizing it in the Security & Privacy panel.

Start by reproducing the MacOS X behavior after installing TableTool from the App Store: the developer is not recognized, and reopening a closed file requires repeated authorization in Security & Privacy. No source file or test is identified in the issue; done means the app and its files can be reopened without repeated authorization.
