I have some web applications (java applets) which have trouble running with Java 7 and java 64 bit.
The tech support wants me to install Java 6 and disable Java 7, here are the instructions:
Please download and install the Java update named "JavaForOSX2013-05.dmg" from Apple for better security. For OS X 10.7 and above: http://support.apple.com/kb/DL1572
After that, please follow the instructions below to re-enable the Apple-provided Java SE 6 web plug-in and Web Start functionality: http://support.apple.com/kb/HT5559
Security-wise, is it safe to setup OS X this way?
