Why after stating in a Compressor (Apple) Droplet to use the computer's cluster does it work when it wants to insofar as sometimes they render with 'My Compter' and other times 'with my computer's Cluster' very confusing and annoying when you need the speed of the cluster to do its thing.
I have also got the cluster switched on in the Qmaster prefs.
QMaster is known for being unreliable. Sometimes my virtual cluster is available, sometimes it isn't; I don't know why. I used Virtual Clusters on 4 different computers and they all had the same issue: sometimes the Virtual cluster was available, sometimes it wasn't.
