OS X 10.8 Message: "The app can't be opened, because it is from an unidentified developer"

Affects OS X 10.8 and Later: You may see a message warning you that the downloaded package "is not from an identified developer". You can safely ignore it. Cognitone uses a packaging method (multiple packages bundled) that is currently not recognized by Gatekeeper. The actual software being installed is properly digitally signed and registered with Apple.

Message: "Error -5000 while verifying your authorization" (Mac)

This message indicates that one or more folders on your Mac have restrictive permissions that hinder Synfire from looking up system information. On a clean OS X installation, this should not happen. For whatever reason, the default permissions were modified on your system. A -5000 error is an Apple OS X message that is not solely related to Synfire. It can occur with any application.

Message: "You can't open the application because it may be damaged or incomplete" (Mac)

If you happen to get the message "You can't open the application because it may be damaged or incomplete" when starting HN2 or Synfire Pro on a Mac, you should do the following:

  1. Be sure you are logged in with a user that has admin rights.
  2. Run Disk Utility's "Repair Permissions" on your startup volume.
  3. Reinstall the Cognitone software.

We do not know yet why this happens in the first place, but it seems to happen to a few users every now and then. We were unable to reproduce the message on any of our Macs.

Propellerhead Folder Permissions Fix (Mac)

This shell script fixes file and folder permissions in the Propellerhead Software folder. Use this in case some other software installer has messed with the permissions and you can no longer install or update Synfire Pro. This script is meant as a workaround until we will have changed the installer to ask you for admin privileges and make these modifications automatically.

Message: "[E0543] The MIDI subsystem configuration failed" (OS X)

Read this if you are having problems installing a Cognitone product (earlier than HN2 version 2.5 or Synfire Pro version 1.5 only) on your Mac (solution applies to error messages "The MIDI subsystem configuration failed" and "Please make sure Macintosh HD can be written to by the current user").
