Apple has released iMovie 10.0.2 with fixes for unspecified issues that were causing the video editor to crash. The update also fixes two sharing issues: one that would cause sharing to fail outright and another where the Share button would not respond. Other changes include fixes for instances of blank project thumbnails and high-resolution images that appeared green, plus resolution of a problem where the Crop, Ken Burns, and Map features were not accessible on Macs using certain languages. iMovie 10.0.2 now requires OS X 10.9.1 Mavericks. ($14.99 new from the Mac App Store, free update, 1.94 GB)
Better Text Formatting in iPhoto
If you're creating a card or book in iPhoto, and you're not happy with the formatting options for the text (such as line spacing or justification), copy the text out to TextEdit, make the changes you want there, and paste it back into iPhoto, which will retain your changes.
