Frequently Asked Questions
If you see this message when trying to use Name Mangler's Services…
The “Rename” service could not be used because the “(null)” application is corrupt. Try reinstalling “(null).”
…you're using Name Mangler on OS X 10.10 or older: There's some sort of issue there (at the OS level) that prevents Name Mangler's Services from working properly. We can't fix this, and it's highly doubtful Apple will ever fix these older releases.
The workaround is to use Droplets (File > Create Droplet) in older versions of Mac OS X.
