Hello, I followed this tutorial on how installing SL's Preview on Lion. But unfortunately the procedure doesn't work with Mavericks. When clicking the app's icon, I get "You cant use this version of the application PreviewSnow.app with this version of OS*X". Looks like it's an artificial (business) restriction and not really a compatibility as it worked on Lion. Is there a way I can run SL's Preview on Mavericks. The newer one is worse for reading PDFs... wider sidebar, horrendous slow font-smoothing (I already tried every defaults command for removing font-smoothing system wide, but appears that Preview uses its own smoothing algorithm).
