QuarkXPress and OS X Mountain Lion
With the release of OS X 10.8 (Mountain Lion) on Jul 25, Apple introduced a new security feature called Gatekeeper, which helps you to keep your computer free of malicious software that you downlaoded. Gatekeeper allows only software from trusted sources to be installed: Apps from the Mac App Store, and apps from registered software vendors who have built their installers with a Gatekeeper signature.
Because QuarkXPress 9.3 was released before Apple introduced this new feature, Gatekeeper (at its default settings) does not allow the installer for QuarkXPress 9.3 (or earlier) to launch if you try to install from a downloaded Installer.
However, there are two ways to install QuarkXPress 9.3 (or earlier) under Mountain Lion:
- Control+click/right-click the installer icon and choose Open.
- Open System Preferences, click Security and Privacy, display the General tab, and then click Anywhere under Allow applications downloaded from.
(After installation, be sure to return this setting to its default state.)
While Quark has been testing with Mountain Lion for several months, the team is currently wrapping up testing. So in a few weeks, Quark will release a free update for QuarkXPress 9 that is compatible with Gatekeeper and has been extensively tested on the release version of Mountain Lion. That version of QuarkXPress will be the first version officially supported on Mountain Lion.
Until this upcoming version is released, Quark recommends that you use QuarkXPress 9.3 on Mac OS X Leopard, Snow Leopard, or Lion.
Update Aug 5:
Current test results and customer feedback show that for most customers QuarkXPress 9 seems to work fine under Mountain Lion with the exception of the Gatekeeper limitation.
However when using Mountain Lion with a few specific Graphics Cards, the Welcome Screen of QuarkXPress causes the application to crash. So far we know of ATI/AMD Radeon HD 5750M, ATI/AMD Radeon HD 5770 and ATI/AMD Radeon HD 6750M having this issue.
Remedy: Remove the "Welcome Sceen.xnt" from the XTensions folder.
We are working on a fix for this.
Update Aug 13:
We just released QuarkXPress 9.3.1, which is now also supported under Mountain Lion.
