Q. Is it possible to check if permissions are wrong on some or all of the items in the /Library/Application Support/InterMapper Settings folder?

A. You can check the permissions by opening a terminal window and doing the following:

cd /usr/local/bin
sudo -u intermapper ./intermapperd --verify-permissions

If the permissions are correct, there should be two lines of output:

Checking permissions of /Library/Application Support/InterMapper Settings
XExitProcess(0): Permissions checked.
