Lion release breaks numerous Adobe titles

updated 10:50 am EDT, Thu July 21, 2011

Flash Player loses hardware acceleration

The release of OS X Lion is causing problems with a host of Adobe software, a support article shows. "Known issues" of varying degrees exist with high-profile titles such as Acrobat, Dreamweaver, Illustrator, Lightroom, Photoshop and Premiere Pro. The biggest problems however lie with Flash, spanning apps like Flash Builder, Flash Catalyst and most notably Flash Player.

Whereas the latest versions of Builder and Catalyst may simply not work well in Lion, Player is experiencing higher CPU use in Lion due to hardware acceleration being disabled. Flash is already an infamously resource-intensive plugin, particularly on Macs, which have long had more trouble with the software than Windows PCs. Apple CEO Steve Jobs has in the past singled out Flash for causing stability and security issues.

Some other key Lion issues with Adobe software include the lack of Safari 5.1 compatibility for Reader and Acrobat plugins, and Droplets breaking in Photoshop CS3 through CS5. Adobe also points out that because Lion abandons Rosetta, any software from CS2 or earlier will no longer function.

Regarding taking advantage of the new features in Lion, such as Auto Save, Restore, Versions, Full Screen Mode and added gestures, the company says it is still undecided. "Since many of these features require new code in order to work properly, Adobe will investigate which ones make sense to our customers for inclusion in future versions of our products," it writes.

    Adobe Remains Late to Need

    Again why Flash and Apple OS community second class citizens.

    What's "lazy" in Spanish?

    Adobe ("house" in Spanish) has had a year to get ready for this. Apple isn't trying to do anything other than advance my user experience.

    doesn't surprise me

    Adobe is a Mac developer so they have had access to the beta versions like all developers. Adobe is like Quicken, refusing to keep current, relying on old software to make as much money as they can without doing any new work. I'm loading Illustrator CS4 and Acrobat to see if they will work. These are the only two Adobe applications I need and I'd rather replace both but haven't found an adequate replacement for Illustrator and creating forms in Acrobat is better than in other applications. I always remove their Safari pdf plugin anyway so that doesn't bother me.

    Join the Program

    Adobe really needs to join the Apple Developer Program to get pre-release and betas of Apple's new OS. That way they can warn their users of any possible issues. Yeah, right.

    I just tested Flash Builder 4 and Flash Catalyst CS5. At first glance they appear to work. Based on the tech doc they make it sound like they don't work at all. Then again it's not my work computer so I just opened them up quick threw together something simple.

    an this is why subscription might suck

    Suppose you just subscribed to accomplish a short term problem when something like this happens...Adobe gonna give you a discount??? Not!

    going to miss Rosetta

    looking forward to Lion, but it's going to be difficult without Rosetta. there's a lot of good software out there which hasn't been keeping current. hopefully, kicking the Rosetta crutch out will prompt some updates, though.

    No excuse

    There is no reason.....Lion has been available to developers for a while they should have had updates available on release day or soon after!

    Adobe PSE should be OK

    If it isn't sold thru the AP store I doubt they'll pay much attention.

    InDesign 5.0 and 5.5 seem to be OK, with the only problems being the now-hidden user Libraries folder and Lion not shipping with Java. Those aren't anything Adobe could have prepared for. Hiding Libraries is just Apple being silly. Like hostility to Flash, not including Java (and soon not supporting it) is just part of Apple's growing tendency not to 'play well with others.' That'll probably lessen after Steve Jobs retires.

    Adobe may take a pass on adding higher-level, Mac-specific Lion features such as Versioning and Full Page. Because they develop for Windows and OS X, they usually do things their own way, so the Windows and Mac versions are alike. In fact, InDesign already has a Full-page-like feature.
