Symptoms: I upgraded to OS X 10.7 or newer, now when I try to start InterMapper, it fails.

There are console messages like this:

24/07/11 5:43:41.630 PM com.apple.launchd:
(com.dartware.InterMapperDataCenter[2330]) getpwnam("intermapper")
failed
24/07/11 5:43:41.644 PM com.apple.launchd:
(com.dartware.InterMapperServer[2331]) getpwnam("intermapper") failed

Cause:

OS X has changed the settings on the InterMapper Settings directory.

Solution:

Back up your /Library/Application Support/InterMapper Settings folder as a precaution (always a good idea when upgrading) and reinstall the latest InterMapper.

We are only repairing the permissions on the directory - no data will be lost.
