OS X Lion breaks Adobe products including Photoshop, Flash

The war between Apple and Adobe appears to be continuing. Last year, Apple continuously fired pot shots at Adobe claiming their Flash software causes bad performance, and subsequently announced it would never support the products on the iPhone or iPad, nor would it allow applications that use workarounds to enable it. Adobe responded by launching a "We <3 Apple" and "We <3 Choice" campaign which was targeted directly at Apple's attitude towards its products.

Now, it appears Apple has taken another step to push Adobe away from its platforms. Early reports incorrectly suggested that Apple had disabled GPU support for Flash Player in all browsers. However, the Adobe support page reports that there is an issue where "Flash Player may cause higher CPU activity when playing a YouTube video" but this is a seperate issue, and hardware acceleration has not been disabled. Neowin has heard multiple reports of users having their entire OS crash when the software is used in a browser.

Venture Beat reports that Adobe is listing issues with Acrobat, Dreamweaver, Fireworks, Flash Builder, Flash Catalyst, Illustrator, Lightroom, Photoshop, and Premiere Pro. Apparently, some older programs will no longer run at all, such as Flash Builder and Catalyst which are listed as "will not work on OS X 10.7." Adobe says it doesn't plan on updating the programs to work on the platform. 

Other issues affect the massively popular Adobe Photoshop and Illustrator software, with the "droplets" feature being broken in Photoshop CS3, CS4 and CS5. On top of this, in Illustrator CS5, save or export is disabled from the "Save As" and "Export" dialog when saving to the desktop. In Adobe Lightroom, Nikon cameras are having issues with tethered shooting, with Adobe's only workaround being "remain on Mac OS 10.6.7 until the issue is resolved." Adobe Lightroom 2.7 is now no longer listed as "working."

Finally, the Adobe Reader plugins are no longer compatible with Safari 5.1, with the support website saying that Safari 5.1 replaces Adobe's plugins and can render PDF documents natively. The software still works as a standalone solution, but may cause issues with LiveCycle and Acrobat where they expect the plugin. Adobe says that users should continue using OS X 10.6 until the problem is resolved.

It's puzzling as to why so many issues are in this release of OS X. Previously, Adobe and Apple worked closely on new releases to ensure that their products worked seamlessly and caused no issues. Venture Beat points out that software developers are given access to beta versions of Apple's upcoming OS to get everything working, yet it seems someone dropped the ball in this case.
