Sabotages further app installations
Mac OS X Snow Leopard is preventing some users from installing any further software, posts on Apple's support forums indicate. After upgrading to the OS, users may find that Installer is incapable of completing any kind of installation, whether in terms of first- or third-party programs. Because of Installer's deep integration into Snow Leopard, it is even preventing minor upgrades of existing applications, such as Aperture.
The source of the problem is unknown. It may only affect users upgrading from Leopard however, as at least one user reports that a clean installation of Snow Leopard causes no conflicts. The issue also appears to be independent of hardware, affecting several models of Mac. Apple has yet to comment on complaints or offer a solution.
