I've been a PC user until this year and used Adobe Acrobat all the time on my PC. It's an invaluable resource. I moved to an iMac this year and although the Mac has a built-in PDF creator it's very limited in its capabilities. I tried to research the professional PDF creator options for the Mac but there isn't much written out there so decided to bite the bullet and bought the Adobe Acrobat Mac product. It's just not comparable. The functionality is very limited compared to the PC and as a result I now need to use Dropbox to sync documents with my old PC so that I can use the full functionality of Acrobat on my PC as this Mac product is all but worthless. Don't rush out and buy this until they resolve the issues OR just buy the cloud version (£13/month) of acrobat which doesn't have the limitations that this Mac-specific version has. Very disappointed. Currently no better than the cheaper PDF creator products that are available for the Mac.
