ADOBE.GIF Adobe Clarifies Photoshop CS3, Snow Leopard Compatibility

Relax, it runs.

Late today, Senior Photoshop Product Manager John Nack clarified the compatibility of Photoshop CS3 and Apple's OS X Snow Leopard, which is scheduled for release in two days on Aug. 28.

"It turns out," Nack wrote on his blog, "that the Photoshop team has tested Photoshop CS3 on Snow Leopard, and to the best of our knowledge, PS CS3 works fine on Snow Leopard."

The blog entry confirms a number of informal reports from developers with the latest seed of the operating system that the Intel version of Creative Suite 3 runs without issue on Leopard. Nack did point out two open issues:

1. The blue highlight ring around PS windows displayed by Exposé is too heavy.

2. When using arrow keys to nudge the values in text fields up and down, the values now change more slowly on a Japanese OS.

The company has posted a FAQ on the compatibility between Mac OS X Snow Leopard and Creative Suite 4, the current implementation, available as a PDF. The company confirms in that document that "Adobe has tested and determined that our Adobe Creative Suite 4 products and components are compatible with Mac OS X Snow Leopard" although Nack noted two exceptions:

• auto-updates to Flash panels and

• Adobe Drive/Version Cue

But in the same document, Adobe addressed CS3 compatibility with the new operating system, saying:

"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)."

While Adobe has no plans to release updates for CS3 issues under Snow Leopard, Nack said, "we have reason to expect that all meaningful issues of running Photoshop CS3 under Snow Leopard have been resolved. However, because we have not done the level of testing that true certification demands, we need to stand by our statement that we don't officially support CS3 on Snow Leopard."

PowerPC plug-ins and device drivers (for scanners, as an example) will require the Rosetta PowerPC code interpreter, as they do on Intel Macintoshes now. According to reports from developers familiar with the prerelease versions of Snow Leopard, the upgrade process will detect PowerPC applications and drivers and install Rosetta. You can also opt to install Rosetta during installation. And if you try to run a PowerPC application without Rosetta, you will be prompted to download and install it.

Two Additional Adobe Notes

ACR 5.5

Last week, Adobe released its Photoshop Camera Raw 5.5 plug-in and DNG Converter 5.5 Release Candidates at http://labs.adobe.com. The update extends Raw file support to four of the latest popular camera model releases, including the Nikon D300s, Nikon D3000, Olympus E-P1 and Panasonic DMC-FZ35. In addition, the Camera Raw 5.5 Release Candidate also includes a correction to the demosaic algorithms in the Raw conversion process for Bayer sensor cameras with unequal green response.


Also of note, the company introduced new features on Photoshop.com, including Group Albums and support for video upload, playback, and sharing.

With the newly added video upload capabilities, users can upload videos up to 200MB in size through their browser, or up to 2GB through the Adobe AIR Uploader in most major file formats. These videos can be shared with friends and family and viewed directly on Photoshop.com.

And with the new Photoshop.com Group Albums feature provides a fun, group members can share a single collaborative album with drag-and drop ease, make creative and entertaining edits to each other's photos, and post comments on photos and videos for their friends and family to see.
