Pagesmith works with Mac OS X 10.6 Snow Leopard or higher.
Snow Leopard adds support for text replacement in Cocoa-based applications. Pagesmith already has its own text replacement system. You can continue to use Pagesmith text replacement, or use Snow Leopard text replacement, or use both.
To activate Snow Leopard text replacement in Pagesmith:
Snow Leopard changes the way your Mac works when you double-click a file. PDF files always open in Preview, regardless of the application that created them. In our view, this is a major design flaw in Snow Leopard.
Pagesmith allows you to insure that double-clicking a PDF file will open it in Pagesmith if it is a Pagesmith PDF, or in Preview (or another application of your choosing) if it is not a Pagesmith PDF. This is how double-clicking has always worked on the Mac before Snow Leopard.
To allow Pagesmith to manage double-clicking on PDF files:
When Pagesmith manages double-clicks on PDF files, it uses a small helper application to examine the file and determine whether it is a Pagesmith PDF. The full Pagesmith application is launched only if the file should be opened in Pagesmith.
