Mac OSX has created some limitations when using MultiLedger in multi-user mode. If you choose to have your company files reside on a Mac OSX computer, you may open it from that computer as a Single user only, meaning that no one else can access the files remotely at that time. When the user on the host computer is not using MultiLedger, users on other networked computers using OS 9.x or OS X can open the files remotely.
Tip: If you are using OSX, please make sure you have the most recent 6.0.7 or 7.0.8 version of MultiLedger running on your computer.
