I have been a Mac user for more than 30 years and have gone through the generational changes as each became obsolete. Had to abandon my IMAC desktop that could not handle the latest Safari or other upgrades. Now have Mac book pro. My problem is that i have a biography with photos, etc that I passed along via floppy disks and CDs in PDF form. Original was done in Pagemaker... anyone remember that? The PDF version is excellent except I would like to edit, update and add to it. What is the latest software that would allow me to scan and edit without a major redo/retyping?
