So, you're saying that clicking 'Build Audiobook' doesn't begin the build process that generates a new file? Builds are working as expected to here in our tests and we haven't received reports from other users that aren't able to build, so the issue may be unique to your Mac. Would you be willing to reproduce the issue and then generate a System Information report to send over to us? This report may provide an explanation. You can create one of these reports by clicking the Finder icon in your Dock, going to the Go menu at the top of your screen, clicking the Utilities menu item, opening System Information.app, then going to the File menu and clicking the Save... menu item. Attach the resulting file to an email to us at
support@splasm.com and we'll have a look.
