Various OS X related scripts to setup/automate a Mac
I switched from using Apple's Preview to Smile Software's PDFpen to view and manipulate PDFs. The automator automators/PDFpen/Batch OCR folder.app will OCR a file(s) and folder(s) dragged and dropped onto it. There are two workflows inside the Automator script and you should enable the one that is best suited to your needs.
OCR filewill only OCR a file if PDFpen thinks it has not been OCR'd. If selectable text is present, PDFpen thinks the file does not need to be OCR'd. 99% of time this is the correct choice.OCR file with overridewill pop-up a dialog box asking you if you want to force OCRing. The automator will wait until you make a choice so it's not ideal for unattended operation.
When you pull these scripts to your computer, the files need to be re-associated with their workflows in Batch OCR folder.
