2. You may have to disable Mac OS Gatekeeper

There's a security feature called Gatekeeper on Mac OS that prevents apps that are not downloaded from the Mac Store from running. To disable this feature, go to the Apple Symbol menu > Sytem Preferences > Security & Privacy > General > and look under the section Allow apps downloaded from: > Make sure the raido button Anywhere is selected.

3. You may receive this error if you have IVox version 3 voices installed on your Mac OS

If you have IVox version 3 voices, Kurzweil may receive an error on launch. This is currently a known issue that is being investigated by our engineers for a solution. The current workaround is to go back to IVox version 2 or lower voices, please see below for more details.

How to resolve the IVox issue:

1. Perform a spotlight search for IVox, this should locate the IVox Voice Manager, open it.

2. Go to Tools > Uninstall Infovox IVox

3. Reboot, after rebooting the IVox voices should be fully removed, they should no longer show in Kurzweil as choices.

4. If you would still like to use the IVox voices, you could install the v2 IVox voices at this point, as version 2 of the IVox voices are not known to cause a conflict at this time.

If you need more information about your IVox installation, refer to the official IVox manual here.
