Apple users on the last two versions of Mac OS X are getting a security upgrade for Java. The new version for 10.6 Snow Leopard and 10.7 Lion will set web browsers not to automatically run Java applets, making it harder for malware to sneak in. Although it's possible to set them to run automatically from preferences, the setting will turn off again if use Java for a long enough period of time. This is a feature Apple first introduced for Safari only in Lion, back when it dealt with Flashback malware in Java. As we mentioned before, it makes running Java a bit less seamless, but it's also a safety precaution meant to prevent a recurrence of Flashback, which infected some 600,000 Macs. It should be showing up as an automatic update and can also be found here for Lion or here for Snow Leopard.
