By default, Mac OS X 10.7 Lion doesn’t come with a Java runtime, but this doesn’t mean that users who need to run Java apps (such as the popular CrashPlan) are out of luck. Apple now makes Java SE 6 1.6.0_26 available as a separate download that the operating system will automatically attempt to install whenever users try to run a Java app, or that can be downloaded separately from the company’s support Web site. Apple recommends that all Web browsers be closed prior to beginning the installation process. (Free, 62.53 MB)
