Known issues | Adobe on Mac OS 10.7 Lion

Global issues

Files stored in Library folder

In Mac OS 10.7, the Library folder is hidden. Preferences, presets, and other user customization settings are stored within this Library folder.

To access the Library folder:

  1. In the Finder, choose Go > Go To Folder.
  2. In the Go To Folder dialog, type ~/Library
  3. Click Go.

For instructions on additional methods to make the Library folder visible, see How to access hidden user library files | Mac OS 10.7 Lion.

Java Runtime isn't installed by default

Some features in many Adobe applications require the Oracle Java Runtime Environment (JRE). In Mac OS 10.7, Java is no longer preinstalled but is an optional installation item.

Current Adobe installers and applications were built before these changes to Mac OS and anticipate that Java is installed. Adobe and Apple worked together to ensure that you can install Java with Mac OS 10.7, or at a later time before you install Adobe applications. (When you start an Adobe application, you are prompted to install Java if it isn't already installed.) In a corporate IT environment, be sure to preinstall Java, or make sure that it can be installed through firewalls or other security software.

 If the Java Runtime isn't installed, the following issues can occur in Adobe applications: 

  • Features are missing or behave improperly
  • The software doesn't start
  • Prompts to install Java Runtime occur
  • Applications hang or quit

For instructions to install the Java Runtime, see How to install the Java Runtime (JRE) | Mac OS 10.7 Lion.

Crash Reporter delays

In Illustrator CS5 and CS5.1, and in InDesign CS5.5, Crash Reporter doesn’t appear or appears after long delays (10-15 minutes).

Scrolling behavior is opposite of expected

When you scroll, the result could be the opposite of expected due to the "Move content in direction of finger movement when scrolling or navigating" feature. To alter this behavior, deselect the feature at the top of the Mouse section within the System Preferences.

Rosetta not supported

CS2 and earlier versions of Adobe products require Rosetta to run on newer Intel-based Mac systems. These older versions are not supported on Mac OS 10.7 as it doesn't support Rosetta.

Support for Mac OS 10.7 new features

Mac OS 10.7 has some exciting new features such as Autosave, Restore, Versioning, Full Screen Mode, and more multi-touch gestures. For Adobe applications to fully support these features, additional product development is required. Adobe is working to address this issue. For related information, see Mac OSX 10.7 preference to "Restore windows when quitting and re-opening apps" doesn't work with Adobe applications.

Product-specific issues 

Acrobat family

Adobe Reader plug-in and Acrobat plug-in are not compatible with the Safari 5.1 browser, included with Mac OS 10.7 and for 10.6 in July 2011. Adobe Reader and Acrobat continue to work as stand-alone applications on Mac OS 10.7 and 10.6, and render PDF documents outside the browser. In addition, Safari 5.1 renders PDF documents natively. However, the Adobe Reader and Acrobat plug-ins don't function as expected in LiveCycle. And Acrobat workflows that require either plug-in to render PDF documents in Safari 5.1.


If you use forms, digital signatures, portfolios, guides, 3D, extended PDF documents and rights management, and require the Acrobat plug-in to render PDF documents in the Safari browser, Adobe recommends that you continue to use Safari 5.0.x and Mac OS X 10.6. Adobe will provide updates as it continues to investigate this issue. For additional information, see Apple Safari 5.1 and Adobe Reader/Acrobat Advisory.

Adobe Drive 

When Adobe Drive 2 or 2.1 connects to a digital asset management (DAM) server, Photoshop, InDesign, InCopy, Illustrator, and the Mac OS X Finder can't display folders or files in second-level folders of a mounted drive. Adobe Drive 3 addresses this issue. For additional information, see Folder contents not visible in drive mounted on Mac OS 10.7 | Adobe Drive 2.x

Adobe Connect

The Adobe Connect Add-in is not officially supported for use with Mac OS 10.7. For more information, see Known issues with the Adobe Connect Add-in version and Mac OS X Lion.


Contribute CS5, CS5.1

  • Contribute detects LPDF files as PDF files. An error message appears during publish.
  • The Contribute plug-in crashes when you select text or add a highlight color outside the color panel in the Firefox browser (Contribute In Browser Editing).
  • Publishing Content Type with metadata enabled results in Content Type being successfully published but the metadata is not created or populated. Such categories of XML files cannot be edited because validation fails on Lion.

Contribute CS4

  • The color picker does not select color outside the color picker dialog box.



In Fireworks CS4, the color picker doesn't reflect the color selected on canvas. 

Flash Builder

  • Flash Builder 4.0.x doesn't work on Mac OS 10.7. Adobe does not intend to update this product for use on Mac OS 10.7.
  • Flash Builder 4.5.x is compatible with Mac OS X 10.7, although issues can affect installation and product usage:
    • Before installing Flash Builder 4.5.1, install Java for Mac OS X 10.7.  Otherwise, Flash Builder 4.5 is installed instead of 4.5.1. For instructions to install Java, see Install the Java runtime (JRE) | Mac OS 10.7 Lion.
    • Flash Builder includes a version of Flash Player that is not recommended for use with Mac OS 10.7. Rather than installing the default version, download and install the latest debugger version.
    • Right-clicking in the package explorer can stop working after prolonged use of Flash Builder. To resolve the issue, restart Flash Builder.
  • Flash Builder 4.6 for PHP when installed as a plug-in into Eclipse 3.7 is generally compatible with Mac OS 10.7. However, if you are using a stand-alone configuration of Flash Builder 4.6 for PHP (Flash Builder 4.6 integrated with Zend Studio), right-clicking in the Package Explorer is sometimes unresponsive. To resolve the issue, close and reopen Package Explorer. If the issue still exists, restart Flash Builder.

Flash Catalyst

Flash Catalyst CS5 and CS5.5 are compatible with Mac OS 10.7. However, some issues affect usability of the product.

Flash Player

Adobe recommends using Flash Player to get the best experience with Mac OS X Lion. In particular, this version resolves an issue with Flash Player settings panel not responding to clicks in Mac OS X Lion.

Flash Pro

  • Flash Pro CS4 doesn't work on Mac OS 10.7. Adobe doesn't intend to update this product for use on Mac OS 10.7 and recommends not using it on Mac OS 10.7.
  • Flash Pro CS5 and CS5.5 are compatible with Mac OS 10.7.


In Illustrator CS5 and CS5.1, the option to save or export is disabled in the Save As Or Export dialog box if the save location is the desktop. See Save/Export button is disabled on OS 10.7 | Illustrator CS5/CS5.1.

Photoshop Lightroom

Photoshop Lightroom 3

Photoshop Lightroom 2.x

  • Photoshop Lightroom 2.7 is verified to support Mac OS 10.7. Earlier versions were not tested, although they could run on Mac OS 10.7 without issues. However, Adobe recommends that you update to version 2.7. From within Photoshop Lightroom, choose Help > Check for Updates. 
  • Photoshop Lightroom 2.x doesn't install from the installation DVD. For details, see Lightroom 2 doesn't install under Mac OS X 10.6 and 10.7.


Workflows that are dependent on the Adobe Reader plug-in don't function.


Adobe Premiere Elements

  • In Adobe Premiere Elements 9, color artifacts appear in the Timeline area when moving clips within Timeline view.
