Apple has issued a System Management Controller (SMC) update for the MacBook Pro with Retina Display, which fixes several sleep and wake issues for users running Mac OS X 10.7.4 Lion. Additionally, like the SMC updates recently issued for MacBook Air models (see “MacBook Air SMC Updates 1.5 and 1.6,” 27 July 2012), this one enables Power Nap support when running 10.8 Mountain Lion.

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.
