MAC OS10.11.6  Finale 2014.5

Does Finale 25 work (efficiently) on an iMac with retina display?  Very disappointed to buy a 2015 27" iMac retina and have to run Finale in Low-resolution.  I hope this has been addressed.

And- how is the speed?  Finale is crawling along in my current project, despite tons of memory and late model machine.  Waiting for redraws again, like in the 90s....!
