I am editing some PDF (adding bookmarks) on my MBPro and want to be able to edit it on the iMac as well. How could I do this? Is there some sort of online software, like Google Docs, that allows for inserting bookmarks on PDF files? Is there a way to have the whole HD in an online cloud so that whatever I do on the MBPro same changes would happen to iMac? Or rather I would be accessing the same stuff from a cloud?
