PDFPENPRO SIGNATURE NOT SHOWING UP IN PDF MAC OS XThere is a way to prevent these automatic saves on Mac OS X Lion (this one is not available in Mountain Lion) is to edit your TimeMachine configuration and make sure that the file gets locked after a certain time frame (unfortunately, the shortest possible time frame is one day). In my opinion, this setting should be checked by default, but Apple decided that we need the same user experience as on iOS devices, where we don’t need to worry about saving documents.
