I'm filling out an online pdf form for myself and someone else.  I saved my form OK, but it's not letting me save another copy.  The ERROR MSG I get is:


The document could not be saved. There was a Macintosh system error (-51).


Please help!


Thank you

Adobe Reader 9.5.2, Mac OS X (10.5.8)

    Try a copy and paste, of unless there is different information on iy. In which case, can you download the PDF again and fill it out with the different data.

    Or a PDF editor.

    Hi Sanjampet,


    Thank you for responding.  Adobe is not letting me open a blank form while the current one is still open, and I am reluctant to close the form because it has 7 pages of info typed into it!

    Tr saving it, printing it, putting it on a USB drive.  Try on a different computer.

    So that I understand, is the PDF you are attempting to "fill out" still residing "online", or is the PDF downloaded to your computer and you are working on it from there?


    I don't think Adobe Reader will let you "save" files, hence the name Reader. You would need the Professional version of Acrobat.


    Also, there may be some security features on the PDF that will not allow you to "save" it.

    Hi RMGMAN,


    Thank you for responding. 


    The PDF is downloaded on my computer.  And I have successfully saved a first filled-in copy for myself.  What happened next was, I reopened the blank form and started filling out the form for someone else.  Initially it did allow me to save this second pdf file, but as I was finishing up it gave me that error (-51).  And now I cannot save it...

    Here is what Apple has to say:

    I'll try this later, right now I don't have access to another computer.

    I tried the Apple suggestions, but there are no


    "File > Save a Version" or

    "File > Duplicate" or

    "File > Export"


    that I can see.

    That was all I could find in the Apple data base, that OSX does not get much support. I don't have a machine with that OSX, so I could not investgate it at all. Maybe someone else on the forum might be able to offer some help.  Sorry I could not help you.

    Thank you for trying though.

    I haven't tried this app, it's free download. Perhaps those with experience with PDF Editor for Mac could speak about it.

    I'm still confused on if you are editing/fillling out the form with Adobe Reader, Acrobat or Preview.


    The info link sanjampet gave you was for Preview.

    I just used Preview for the first time to fill out a PDF form and it worked great except for one problem. When I printed out the form there were yellow highlighted text boxes. I don't really mind the text boxes, but does anyone know how to get rid of the yellow?

    You should never, ever use Preview when filling out AcroForms. Always, always, always use Adobe reader -


    Preview just trashes AcroForms - and if you save as an image then the form designer won't be able to extract the data.
