Note: Microsoft has been working with Apple from the early days of MacOS 10.7 (Lion). Through this partnership, many issues were addressed leading up to the Lion release. Microsoft will continue to work closely with Apple to address problems that may occur with Office for Mac 2008 and 2011 and Lion OS.
Note: Sync services are not available with OSX versions 10.8 (Mountain Lion) or higher.
- Communicator for Mac crashes when you send an IM or start an audio/visual call.
Note: Microsoft will resolve this issue in an upcoming update to Communicator for Mac.
- Office for Mac 2004 will not run on Lion.
Note: Previous MacOS versions supported Rosetta, an Apple Mac OSX bridge technology that enabled applications such as Office for Mac 2004 to run on the latest chip architecture for Mac. Because Lion no longer supports Rosetta, applications that relied on it will no longer function under the new MacOS.
