I don't have a mac, so I'm guessing. Have you perhaps a .irbrc file in your 
home directory? If so, then maybe that is the cause for both behaviours you 
get. Try running irb with the -f command line option, which disables reading 
the .irbrc file, and see what happens.

Regarding the prompt issue, the >> prompt can be obtained by using the
--simple-prompt command line option, so maybe you can override this passing 
the --prompt-mode default option.

I hope this helps
