I have ROOT 5.34.36 installed on MacOS 10.12 (Sierra) via Homebrew and this installation appears to be working fine. When I try and start PyROOT, everything seems normal until I try and draw anything.
$ ipython
Python 2.7.10 (...)
[other details that I can post if needed]
[In a startup script, I `import ROOT as r`
In [1]: r.TCanvas() # with r is my shortname for the ROOT module
Out[1]: <ROOT.TCanvas object at [hex number]>
But here, no window is created. How about something else…
In [2]: r.TBrowser()
Error in <TPluginHandler::SetupCallEnv>: class TGQuartz not found in plugin GQuartz
Error in <TPluginHandler::SetupCallEnv>: class TRootGuiFactory not found in plugin Gui
*** Break *** segmentation violation
[tons more errors]
Any suggestions would be greatly appreciated!
