(No matter how you copy the file from the dmg, the OSX will still remember that it was downloaded and then it will claim it is damaged and it can’t be opened - it is a “clever” system on Apple part with some very interesting word choices to discourage you to run anything else that didn’t come through APP Store). To change these preferences on your Mac, choose Apple menu > System Preferences, click Security & Privacy, then click General.Īfter you copy the file to Applications and then try to run it on recent MAC OS (Catalina, Big Sur) it may show message of it being damaged. This button is available for about an hour after you try to open the app. Note: You can also grant an exception for a blocked app by clicking the Open Anyway button in the General pane of Security & Privacy preferences. The app is saved as an exception to your security settings, and you can open it in the future by double-clicking it just as you can any registered app.

The message about unidentified developer will pop up again but this time there will be also Open button.

Control-click the app icon, then choose Open from the shortcut menu.

Launchpad doesn’t allow you to access the shortcut menu.

In the Finder, locate the DAP6 app in the Applications folder Don’t use Launchpad to do this.This doesn’t necessarily mean that something is wrong with the app. If you try to open an app that isn’t registered with Apple by an identified developer (Yours truly), you may get a warning dialog (depending on your security settings).
