I'm having trouble downloading the core catalogs files for my program on my Mac. How can I resolve this?


The most likely cause of a library download failure on a Mac is a firewall or security program preventing the download. Adding the Chief Architect or Home Designer program as a firewall exception within the System Settings may allow you to download the core catalogs successfully.

To add Chief Architect as a firewall exception on a Mac

  1. From the Apple  menu, select System Settings.

    In macOS Monterey 12 and prior, this was called System Preferences.

  2. Select Network.

    In macOS Monterey 12 and prior, select Security & Privacy instead.

  3. Select the Firewall option, then click on the Options button.

    In macOS Monterey 12 and prior, select the Firewall tab, then click on the Firewall Options button. If this option is greyed out, select the padlock icon in the bottom left corner and enter your user account credentials to unlock this area for modification.

    Selecting the Options button in the Firewall settings

  4. This next dialog allows you to add or remove programs from the firewall list and configure how the firewall handles requests from these programs. Click the Add + sign to add a program.

    Add a new application to the Firewall Options

  5. In the Finder window that appears, select the Chief Architect or Home Designer application.

  6. Verify that the program is set to Allow incoming connections, then click OK.
