Macos – How to launch applications in 32 bit from Terminal in Snow Leopard

32-bitmacososx-snow-leopardterminal

Like a lot of people, I have some issues with launching my applications in 32 bit mode, because of the far-from-perfect LCC 3.1 driver for my Logitech di novo edge keyboard. Basically, I am not able to use the correct keyboard layout when in 64 bit mode (my layout changes when I switch applications which is very annoying).

So I am forced to launch my applications in 32 bits.

Can I do this from the terminal with an exec command? Checking the 'launch application in 32 bit mode' seems to have no effect (but it does work from the gui).

Thanks in advance.

EDIT
I should have precised I am trying to make the mvimscript (given in macvim) launch macvim in 32 bit. So solutions based on open, although launching the application in 32 bit, are not what I am looking for, because they seem not to correctly handle pipes and argument passing.

Best Answer

Use arch -i386 macvim
