CEO Steve Jobs introduced the first piece of news on Wednesday, a new version of iLife, Apple's programmes for managing photos, editing videos and music and doing other tasks.
Other new features include the ability to manage photos in a full-screen view, slick new slideshow templates and the ability to e-mail customized photo-postcards from iPhoto.
The presentation also is likely to yield details about a new Mac operating system. There has also been speculation the company will show off an updated ultralight MacBook Air laptop.
