If Quark 7 won’t launch on your Mac and you get an error stating the the Color Manager.qrc extension is damaged or missing, there is a fix that is working for many users. It seems like some of the color management frameworks get damaged and need to be re-installed.
This has been suggested by a Quark Tech Support person. It did work for many users.
1. Go to > Macintosh HD > Library > Frameworks >
and trash Logosync.framework, Xlan Frameworks, Kodak.CMS (both the files and folders in there).
2. Go to > Macintosh HD > Applications > QuarkXPress folder > For System > QuarkXPress Components > double click to launch and give the location of QuarkXPress folder to install it.
3. Now launch QuarkXPress 7.0 and see the results.
