Make the program usable for Mac
Adobe Acrobat DC is virtually unusable on an iMac. The scrolling is unacceptably slow and cannot keep up. This is an issue that has been going on for ages. I have resorted to using Acrobat reader on a parallels virtual machine, where it is much faster.
Simply scrolling forwards and backwards uses up to 100% of the CPU and no graphics acceleration.
Why the **** don't you fix it Adobe? It's a disgrace.
