I have been using the message + app on the mac El Capitan for a while. It crashes and freezes all the time but mainly works. I got a new mac with high sierra on it version 10.13.4. Now message + just quits immediately after opening. I removed it, redownloaded and installed it from app store but it is USELESS. Since it looks like this has been an issue for at least a year and verizon is not updating the app, can anyone suggest another app that does the same thing on the mac? Or a FIX for this problem?
Help is here for you donjames. We can provide the support you need. I apologize for the trouble you are having with Messages+. Have you tried uninstalling as reinstalling? Were all previous files deleted before a new install was performed? BobbyN_VZW
