Adobe Creative Suite compatibility with OS X Mountain Lion

Adobe Creative Suite compatibility with OS X Mountain Lion

Summary: Creative Suite versions 5 through 6 have good level of compatibility with the recently released OS X Mountain Lion, Adobe says. However, read the fine print and check your workflow before upgrading.


According to Adobe, the company worked closely together to test Creative Suite with Mountain Lion. An Adobe technical note says that there are no CS updates needed for the system upgrade.

However, reading down the compatibility list, I note potential caveats with security and plug-ins. For example, Creative Suite 5 and 5.5 aren't signed by the new Developer ID authentication and require a Digital Signature verification method.

Adobe has added the Gatekeeper signing requirements to our currently shipping applications.  However, our legacy products created before Mountain Lion's Gatekeeper feature was available are not signed. If you download one of those legacy (unsigned) applications, the Gatekeeper security feature may pop-up a security dialog that warns users against downloading non-signed applications from the Internet.

The note said that future Adobe updates for CS5–6 will be handled through the Adobe Updater, the company's new automatic downloading and installation utility.

The concern over plug-ins concerns Rosetta, which no longer supported in OS X Mountain Lion. Adobe said that Creative Suite 2 is now totally orphaned with Mountain Lion. The worry is that ancient Rosetta-dependent plug-ins as well as some drivers for older printers, scanners, and some input peripherals also may stop working under Mountain Lion since they may require Rosetta's PPC support.

So, it's important to check your entire workflow carefully before upgrading.

  • Rosetta / Power PC Compatibility Died with Lion

    Rosetta, the Power PC emulator, stopped shipping with the introduction of OS X Lion last year. This isn't anything new. Mountain Lion is just continuing what Lion started.
  • Not of fan of Apple, but this is rediculous

    I am not a fan of how Apple drops a lot of support for things like Mac's only a little over 3 years old. But when complaining that Mountain Lion does not support some old software because it continues to not support Rosetta a Power PC emulator. That is over the top. For one thing Apple never said Rosetta was going to be a permanent addition. It was a application meant to ease OS X Lion users into a changeover. Personally I have to ask why users so bent on support for older applications that require Rosetta would upgrade the Mac to a OS that does not support it? To me if you plan to move forward you move forward. If you plan to run old apps then you stick with what runs old apps.
