The name of the startup disk of OS X, double-byte characters and umlaut character, if it contains special characters, change the name of the alphanumeric only, start the FileMaker Pro.
Thank you for your post.
user14047 (thank you) may be on the right path. Check that your Hard Drive name does not include any special characters or extra spaces. For testing, you might make your Hard Drive name "MacHD". This is a known issue and if changing the Hard Drive name resolves, please let me know so that I may add this thread to the report.
That did the trick. There was a space in the Hard Drive name and once I took it out it worked.
