Apple has introduced a new security layer in Mac OS X 10.9 Mavericks. The added security restricts the available feature sets of the KYOCERA Mac Driver installed on Macs running OS X 10.9.

Specifically, the added security prevents the loading of Print Dialog Extensions (PDEs) that are not compatible with sandboxed applications such as TextEdit and apps downloaded from the Mac App Store.

A patch can be applied to correct this issue.
