Adobe, one of Apple's most important third-party partners, has commented on its compatibility with Mac OS X Leopard. The company said that most, but not all of its applications are compatible with Leopard without the need for an update.

Adobe Photoshop CS3, Flash CS3 Professional, Contribute CS3, Dreamweaver CS3, Fireworks CS3, Flash Player 9, GoLive 9, Illustrator CS3, InCopy CS3, InDesign CS3, Bridge CS3, Version Cue CS3, Device Central CS3 and Acrobat Connect (Start Meeting) are all compatible with Leopard.

Products that will require updates for full Leopard compatibility include Adobe Acrobat 8 Professional and the company's professional video applications, including Adobe Premiere Pro CS3, After Effects CS3 Professional, Encore CS3 and Soundbooth CS3.

Adobe said it expects to publish free Leopard compatibility updates for the video applications in December 2007 and for Acrobat 8 Professional and Adobe Reader 8 in January 2008.

Older versions of Adobe and Macromedia may work with Leopard, but the company warns there could be "installation, stability, and reliability issues for which there is no resolution." Adobe said these products would not be updated for Leopard.
