Some users have asked why it has taken so long just to add Retina compatibility. The 64-bit update we are working on is NOT just for full retina compatibility -- it's a complete modernization of our entire MacOS code base. This entire modernization (eg moving from 32-bit Carbon to 64-bit Cocoa) has been a prerequisite for retina compatibility.
And it's taken over 1.5 years because Screenwriter is a MASSIVE application with hundreds of features -- many more than other programs. We want to make sure we don't break all the reliable features screenwriters have used for decades.
Apple has provided engineering resources, where their engineers have been working side-by-side with us for several months. That should give you an indication of just how difficult the process is.
I can assure you that this update is our 100% priority (and has been for the past 18 months).
