Specifically with regard to using ActiveTcl 8.5.x with Python on OS X, 
there are some bugs fixed in and; however there are at 
least two serious regressions that exist in  One is a Tk crash 
when attempting to open IDLE's Preferences menu: there is now a patch 
for all current versions of IDLE that works around the problem.  Second 
is a Tk crash when using the clipboard copy command.  That problem 
apparently has been fixed in the top-of-trunk of Cocoa Tk 8.5 (which was 
formerly a separate branch but has now been merged into the main Tk 8.5 
support branch) subsequent to the release of ActiveTk  If 
either of these problems might affect your use, I would recommend 
staying with ActiveTcl for the time being.
