Affected versions

This article applies to all versions of Connect Fonts , running on macOS Mojave (10.15) and later.

Symptoms

When you open Connect Fonts for Mac you get an error dialog; clicking OK quits the application.

‘Error starting FMCore: FMCore error 67112974’ in Suitcase Fusion for Mac

Solution

The macOS hosts file is missing an entry that points the hostname “localhost” to the loopback address (127.0.0.1). Third-party applications or network utilities may remove or change this entry, and Connect Fonts must be able to resolve localhost to 127.0.0.1 in order to connect to the type core.

You can check your hosts file in a Terminal window:

  1. Open Terminal (/Applications/Utilities/Terminal)
  2. Enter the following command and press Enter: cat /private/etc/hosts

The default hosts file should look like this:

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost

If your hosts file does not have an entry for 127.0.0.1 that points to localhost, you can download a script from https://cs.extensis.com/font/replace-hosts-file.zip that will replace your current hosts file with a clean copy. The script must be run from a macOS user account with Administrator privileges.

  1. Unzip repair-hosts-file.zip
  2. Double-click the repair-hosts-file.command file
  3. Enter your macOS password when asked
  4. Restart your Mac
