Illustrator CC Problem with iMac 5K Display
The performance of Illustrator CC (whatever version 2015 / 2017 / 2018) is extremely slow. I was talking with Adobe Support via email and they recognized this problem with all Mac Display 5K. it's unbelievable that this kind of thing happens in an application like Illustrator in computers of last generation of Apple. Apple and Adobe were always companies that thought of professional designers. The conclusion of Adobe Support was that they do not know how to solve this problem with 5K iMac displays. The only possible solution is to use Illustrator CS6, a version that is already 7 years old! I hope Adobe does something about it, what a disappointment!
