Comment 1 garnier 2012-11-08 15:32:01 CET 
On Mac OS 10.8 the problem is not the same :


# Re-establish auto refreshing and verbosity:
/vis/viewer/set/autoRefresh true
/vis/viewer/refresh
/vis/verbose warnings
Visualization verbosity changed to warnings (3)
#
# For file-based drivers, use this to create an empty detector view:
#/vis/viewer/flush
Available UI session types: [ Qt, Xm, GAG, tcsh, csh ]
G4UIQt : Unable to init Qt. Aborted

Graphics systems deleted.
Comment 2 Ivana Hrivnacova 2012-11-14 16:15:05 CET 
A work-around for this problem was to re-order instantiating G4VisExecutive and G4UIExecutive in main so that G4UIExecutive is created before calling vis.mac macro.

The main was changed in this way in the following extended examples:
analysis/AnaEx03
eventgenerator/particleGun
medical/fanoCavity2,GammaTherapy
radioactivedecay/rdecay01

It would be good to add a check in VIS/UI drivers so that in case of a wrong order of creating UI/Vis executive objects, user gets an exception with a meaningful message, before the program stop.
