Most likely you'll have an IP address assigned to your wireless interface of 192.168.something.something, and a default gateway of 192.168.something.1. For now, the important thing to remember is the default gateway.

Now open a browser and go to http://<ip address of default gateway>. YOu should see a menu of options, including the name of the SSID, and any wireless security options. You may have to enter a username and password to get at it. The default username is root, and the password is either blank or something less than 8 characters.

I would seriously read up on setting up wireless encryption for your home network. As much as we all like to think that people won't take advantage of you, that time has passed. Setting up encryption only takes about 5 mouse clicks, a good password, and re-connecting your laptop to the SSID and entering that same password. Use WPA2 as the encryption standard.

One thing I just noticed: Buffalotech website (above) has a knowledge base article that states not all of their equipment will work with the Apple OS. It's an older article, and honestly, not well-written. I'd try using the setup first and see what happens. If it works, great. If not, then worry about it.
Good luck,
