Re: [Visualpython-users] Python-visual in latest Ubuntu

[Bruce S. <Bru...@nc...>]

The implication is that your problem is on the Mac, not Ubuntu. The
problem on the Mac is significantly more worrisome than the Ubuntu
problem, because the platform-specific machinery for creating a window
and handling events is currently implemented in Carbon, for which
64-bit support was dropped. It was not found possible to implement
this in Cocoa, due to thread priority issues.

On the other hand, if you don't require the standard Mac look and feel
but are comfortable with the X11 window manager, you can run VPython
with 64-bit Python on a Mac:
