I have Acrobat Professional XI Mac, which I just installed on my new iMac. I had been copying and pasting from PDFs into Word for Mac 2016 without issue. Uncertain as to why, but now when I paste (choosing Match Formatting as before), nothing shows up in the Word Doc. I do see that in the font field of Word, there is gibberish rather than a font style. Again: successfully performed copy/paste previously and unsure why this problem has surfaced. Any help would be appreciated.
As you have mentioned Mac 2016 ,does that states you are on El Captain?
Also check if Acrobat is updated to the latest patch.
Let us know if that helps.
