Is Reunion 9 compatible with Yosemite or El Capitan (macOS X 10.10 and 10.11)?

Although we haven't received reports of compatibility issues with Reunion 9 and Yosemite or El Capitan, it's important to understand that Reunion 9 is a legacy version and will not be tested with Yosemite or El Capitan. No further maintenance updates to Reunion 9 will be released.

Reunion 13 is the current version.

However, if you are still using Reunion 9, we suggest that you get the latest revision of Reunion 9 (version 9.0c).
