To all who contributed to Mac OS X improvements:
Thank you!
I downloaded and installed last night on Mavericks 10.9. It was
quick, straightforward, and completed in seconds. For contrast, I
talked several new users at an Intro to Python workshop this past
weekend how to install 3.4.1; it took about 5 minutes to guide each
user through installing 3.4.1. The new 3.4.2rc1 installer is a *big*
improvement.
It also seems as if launching the interpreter from the command line
is also faster now :)
