Studying for my medical board exam, I'm using a question bank to prepare for the exam by the name of Usmle World. When browsing the net yesterday, I came across this link, and I followed steps 1a and 1b. http://osxdaily.com/2012/04/07/tips-secure-mac-from-virus-trojan/ Today, trying to open the UWorld app, it gave me this error: I went to the site and download the proper program. Now, I can't locate Java Preferences in my Utilities folder. I was told from another thread that J7 will open up it's own folder...but I'm not sure what to click on to get the app working.
