Is there a way to make vi and vim behave differently on OSX?

Is there a way to have two separate config files or somehow disassociate vi and vim on Mac OSX? Simply, I want vi 开发者_开发技巧and vim to open up in 2 different window sizes. Thanks!

Use the v:progname variable:

if v:progname == 'vi'
    " vi-compatible settings
else
    " full vim settings
endif

Should be as simple as using .virc and .vimrc as appropriate.
