Thanks. All Macs are affected. This issue (see also the other FRUSTRATING issues that BLOCK PRODUCTIVITY on my previous messages in this thread) have been around for ever. As an example of these amazing issues, Adobe Acrobat DC Pro broke the digital signature with certificate on Mac. It took Adobe years to fix it, adven after being reported again, again and again. See the incredible report here: Credential Selected Invalid https://community.adobe.com/t5/acrobat-discussions/credential-selected-invalid/m-p/11202782#M261635 Amazingly, no problem with Adobe Acrobat Reader with such certificate signature issue. All this shows the lack of quality control of Adobe Acrobat for Mac. And worse of all, the lack of customer support when problems are reported. As said, none of those issues arise in other applications like PDF Expert. Just check them out to reproduce them in any Mac. Then, please fix them. Until then, I have switched to PDF Expert. Thanks!
