How to use FM file on 2 macbooks and ipad. Most data entry is done on my Mac. Just need to update/sync copies at the end of the day. We live in rural area with satelite serv. and limited monthly useage, so can't be online while working on FM Database. Confused about best way to safely sync / share /update the file thru itunes, remote, or sharing? Sounds like we cannot have FM File open on both macbooks at same time. Thank you for any input.
