how to switch lang. in OSX

Hi people,

I finally got my mac back from the aut. serv. center. with the new disc and Mac OS installed in my computer. Thing is, they installed OSX in spanish and I need it in english. I'm used to having my mac in english and want it that way, how can I do it ?

thanks in advance.

 

thanks a lot, worked like a charm.

just a FYI to anyone who reads this, the apple service I went through was really lame. It took the service center 15 days to replace a hard drive and I had to call them each and every single time to check on any progress.

I just think that if there is not an Apple store around, nor you live in the states, then consider a little more before getting a mac. The great service, sadly, isn't universal.
