PDF's will not open in Adobe Acrobat Reader DC on my iMac running High Sierra?

More info would be nice. What version of Reader? How are you trying to open the pdf files (online...File>Open from within Reader...etc)? What exactly happens when you try?

First, thankyou for the reply. I am running Adobe Acrobat Reader DC, version 2018.011.20038 on my iMac

I use auto update and have confirmed that I have the latest update in place. I open PDF’s by clicking or ? double clicking on the icon. When I do, a new page opens and is totally black. I go back to the

email or website where the PDF is, click again, and get the same result, whether I do it 2, 3, or more times. This also happens sometimes when I try to open an ‘item’ in some website——for example, I subscribe to a medical CME site where I read some material, take a ‘pretest’, and then click on an option to take the ‘post test’….but it ‘opens’ with a black page. I had no problem with any of this until about a year ago. The same problem appeared on my MacAir about ? 3-4 months ago, which MAY have coincided with my upgrading the OS to High Sierra 10.13.3

I spoke at length today with AppleCare who could not fix this and said that he ‘saw online’ that Adobe was having 'problems of this type’ with High Sierra and may have a ‘patch or fix’——'so contact Adobe’, which I did and learned that the Forum is my only option. Thanks for any suggestions you might have.

PS——Just noted that if I go to my Paypal account online, I can successfully open any of my monthly statements (PDF’s) with a click???????

What happens if you right-click (or the equivalent on a Mac), save the pdf to your desktop, open Reader and use File>Open to open the pdf file?

I tried downloading the PDF's to my Downloads 'file' in Finder, then went to that file in Finder and was able to open the PDFs!  So, Thanks so much for pointing me in that direction.  I suspect that the underlying issue is a compatibility problem between Acrobat Reader and the High Sierra newest version of the Mac OS----hopefully they will fix it eventually.

More than likely it's because you are using a web browser (Chrome for instance) that doesn't use the Adobe Reader plug-in.
