On August 28, 2009 Apple will be delivering Mac OS X 10.6 "Snow Leopard." This upgrade from Apple introduces a few incompatibilities with Reunion 9.
To address these problems, we will be releasing a free update for Reunion 9 users. This update will be named "Reunion 9.0a"
If you use Reunion regularly, we urge you to delay the installation of Snow Leopard until you download and install the free Reunion update, version 9.0a.
During the week of August 31, the free maintenance update will be available here.
If you have questions about Snow Leopard, please visit Apple's Web Site.

Additionally QuarkXPress 7 will not be supported on Snow Leopard (OS X 10.6) or Windows 7.
