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)
Removing Photos from iPhoto
Despite iPhoto's long history, many people continue to be confused about exactly what happens when you delete a photo. There are three possibilities.
If you delete a photo from an album, book, card, calendar, or saved slideshow, the photo is merely removed from that item and remains generally available in your iPhoto library.
If, however, you delete a photo while in Events or Photos view, that act moves the photo to iPhoto's Trash. It's still available, but...
If you then empty iPhoto's Trash, all photos in it will be deleted from the iPhoto library and from your hard disk.
