A knowledge base article from Adobe describes a ton of issues that customers who upgrade to OS X Lion may experience with Adobe software, including Drive, Dreamweaver, Fireworks, Illustrator, Lightroom, Photoshop and, of course, Flash Player.Regarding the latter in particular (for which Apple is known to care very little), Adobe has found that “Flash Player may cause higher CPU activity when playing a YouTube video.”
The software company initially thought this was “possibly” related to disabled hardware acceleration.
However, that didn’t turn out to be the case.
In an update to their original post, Adobe now clarifies that “The final release of Mac OS X Lion (10.7) provides the same support for Flash hardware video acceleration as Mac OS X Snow Leopard (10.6).”
They had assumed the previous “known Issue” suggesting that video hardware acceleration was disabled in Lion because they had done tests with “a pre-release version of Mac OS X Lion that related to only one particular Mac GPU configuration.”
Adobe now says the company is working “closely” with the folks in Cupertino, California “to provide Flash Player users with a high quality experience on Mac computers.”
But there are other Flash Player issues that are sure to stick around until the next update from Adobe is released.
For example, “The Flash Player settings dialog does not respond to mouse clicks,” Adobe acknowledges.
A workaround is using the "tab" key to change the focus to the "Close" button and use the spacebar to close the dialog.
Customers can also fire up the Flash Player native control pane in Lion’s System Preferences.
Adobe also said that it was planning to add support for a bunch of new Lion features like Auto Save, Versions, Restore, and Full Screen Apps (as well as others) in its software products.
"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," the company behind Photoshop said.
