In certain circumstances a Mac will not allow any software to be downloaded unless it has been installed from the App store. As we do not use the App store for downloads, but we are an identified Developer, it is necessary to slightly modify your security settings in order to install E-Stim Connect. If your settings do not allow installations from locations other than the App store, then you will get the following warning

## To change your security settings
