Hello,
first of all, the RND plug-ins currently available online are NOT YET Mac OS 10.10 compatible, the official specs
don’t state something different.
In fact, due to the changes incorporated in the 10.10 update, we needed to spend some time to make our products compatible. The good news is that we already have a working RND beta for Mac OS 10.10. However, the Retina display compatibility is not yet given, but we are currently working on a solution and expect to see a fully tested version (Mac OS X 10.10 & Retina display compatibility) in early Q3.
Thanks,
Timo
