The Macworld 2010 conference program, expected to attract several thousand Apple product users from around the world, will feature six programs: MacIT Conference, Users Conference, MacLabs, Market Symposiums, Power Tools and Creative Safari. All speaker slots for these conference tracks have been filled with leading experts delivering training on the newest and most relevant topics, such as Mac OS X 10.6 ("Snow Leopard") and Final Cut Pro. There are a handful of slots being left open until closer to the event in order to address last-minute, late-breaking topics of interest.

Featured content at Macworld 2010 includes a dedicated, full-day of hands-on training around the iWork suite and an expanded Users Conference that targets a wider base of vertical segments. In addition to creative professionals, photographers, educators, small business professionals and general Mac users, musicians and videographers now have dedicated sessions to help build their skill set.

Sessions will be taught by a faculty of Mac leaders that includes: Rich Harrington, a practiced expert in motion graphic design and digital video and internationally published author of books in the Apple Training Series; Don McAllister, podcasting pioneer and host and producer of ScreenCastsONLINE, a weekly show delivering video tutorials on Apple Mac software to a global audience; and Bruce Nazarian, “The DVD Guy” and CEO of Digital Media Consulting Group.
