Resolving 'File in use' problems on Mac

If Archicad lets one know that a File is In Use by another user and you obviously know that this is not true than it might happen that another application accessed it once and changed this status. There are cases when one can find the conflicting application using these steps:

Open terminal.
Enter the following command:
- sudo fs_usage -w | grep ".pln"
Leave the terminal executing this command.
Go to ArchiCAD and replicate the error leading to the error message.
Go back to the terminal and save the terminal data with "save text as..." from the terminal window menu.
Analyze the saved data and search for application names in it. If you find an application name in this list which is not ArchiCAD then you might be suspicious of that application.

Of course instead of .pln you can write .plp or other according to the real file extension that you have problem with.

Please note that the application modifying your files might be installed on an other computer (e.g. on the server), as well as your local computer.
