We have a database that is continually crashing on Macs. Window users do not appear to be affected. We have over a dozen crash reports from this past week. It doesn't happen on any specific layout or when performing a specific action; sometimes it crashes when it is just running in the background. It is running on FM 13 server. Some of the users are using FM Pro 12 and some are using FM Pro 13. We have switched them to our server to see if there was a problem with server, we have recovered file without any errors, we have uninstalled all plugins to make sure there wasn't any conflict. We are at the point that we do not know what to try to get this working. Suggestions would be greatly appreciated.
