NFCU Scan Deposit on OSX

NFCU's scan deposit feature wasn't working for me. The applet was complaining about 64 bit Java. I fixed this by opening Java Preferences >> General and moving 32 bit java above 64 bit java. Upon retrying the scan deposit feature, the applet complained about not finding a TWAIN compliant scanner, but also a dialog popped up asking if I wanted to install Rosetta to run TwainProxy. I agreed to install Rosetta, and the now it works.
