Install ImageMagick for image conversion:

Install tesseract for OCR:

brew install tesseract --all-languages

Or install without --all-languages and install them manually as needed.

/*
 To use: 
 1) Get path to file/folder using file selection dialog.
 2) Pass path to secscopGetBookmarkFromURL in order to get bookmark data for it.
 3) Store this bookmark data somehow.
 4) Tell the OS you want access to the file using secscopInitializeURLFromBookmarkData(). Store security-scoped url returned for later.
 5) When you are done using the file call secscopStopUsingURL.

 You will need to do steps 4 and 5 every time you want to open a file across sessions. For example, if you have a recent files menu or a folder that a user selects once and you write data to across sessions.
