For the download, please ensure that you do not have Gatekeeper set to block the install. Please use the following steps to do this:

1. Open “System Preferences” (via the dock, or via the Apple menu)
2. Open “Security & Privacy”

3. Go to the “General” tab
4. If necessary, click the lock in the bottom left corner to unlock the tab. You may need to enter your mac’s admin password.
5. Click “Anywhere”
6. In the prompt that pops up, click “Allow from Anywhere”

7. Run the app.

You can possibly reset these settings after you first run Trainz, however we have not tested this.

ALTERNATE SOLUTION:

You may also be able to get Trainz to run by doing the following instead:

1. Control click on the Trainz A New Era.app
2. Choose “Open”
3. Accept the warning about the app being unidentified.

For newer operating systems, such as High Sierra, you may need to follow these steps:

In the Finder, locate the app you want to open. (Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu. )
Control-click the app icon, then choose Open from the shortcut menu.
Click Open.

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.

If you are still unable to load the app, then please try the following:

Select the icon and control-click to get the quick menu, then clicked ’Show Package Contents’

Now in the resultant display box make a copy of that icon, rename it and past it in your Applications Folder. Now try running the app.
