Adobe: CS4 Ready for Snow Leopard, Not So Sure About CS3

| News

Adobe Photoshop Product Manager revealed that the Creative Suite 4 applications are Mac OS X 10.6 compatible on Wednesday, but added a warning that the company hasn't tested the older Creative Suite 3 apps to ensure they won't have any problems.

According to an Adobe FAQ (PDF), "Older versions of Adobe creative software were not included in our testing efforts. While older Adobe and Macromedia applications may install and run on Mac OS X Snow Leopard (v10.6), they were designed, tested, and released to the public several years before this new operating system became available. You may therefore experience a variety of installation, stability, and reliability issues for which there is no resolution. Older versions of our creative software will not be updated to support Mac OS X Snow Leopard (v10.6)."

In other words, CS3 users are on their own if they upgrade to Mac OS X 10.6. That doesn't, however, mean that the Creative Suite 3 apps don't work under Mac OS X 10.6. The Mac Observer's initial tests, for example, seem to indicate that at least Photoshop CS3 performs as expected with Snow Leopard.

The company's Creative Suite 4 apps, including Photoshop, InDesign, Illustrator, and Dreamweaver, are Snow Leopard-ready. "At this time, none of the Adobe Creative Suite 4 products and components requires updates to be compatible with Mac OS X Snow Leopard," the company said.

Mr. Nack, however, elaborated on Adobe's comments by adding that there are some Snow Leopard compatibility issues. "As for CS4, everything is good with the exception of auto-updates to Flash panels, and Adobe Drive/Version Cue which doesn't work at the moment," he said.

While Adobe's announcement is good news for Creative Suite 4 users planning on installing Mac OS X 10.6, CS3 users likely won't be so happy and may want to consider holding off before upgrading to see if any critical issues surface.

Mac OS X 10.6, or Snow Leopard, is scheduled to be released on Friday, August 28. Be sure to check with The Mac Observer for reports on Snow Leopard compatibility issues.

For the price Adobe charges for Photoshop they treat their customers better than this.


Meh. If I finally have to dump DW/FW then that’s what I’ll do. Upgrading to a taller pile of Adobe poo (with Flash panels, no less!) is no longer an option I’m considering. It works as is or I finally change my workflow to something less expensive.

Fresh install of Snow Leopard followed by a fresh install of CS4 Master Collection.

Flash CS4 doesn’t work


I totally agree with the first post. I was loyal to Aldus then Adobe for over 20 years instead of using Quark Xpress. However, now they have a virtual monopoly, they load the prices on each package. Cs4 prices are absolutely outrageous. If they aren’t going to make CS3 compatible with the operating system (Snow Leopard), then I think this sends a clear warning for the future. While I’m on the soapbox . . . Why does almost every other Application’s icons appear as miniature images of the file (including Microsoft Office), but Adobe are just Program ‘blocks’, such as Ps, Ai etc? Not so clever at their inflated prices, and obviously ego.
