How can I open AIM on my MacBook?

Just use iChat. Should already be in your applications folder. An even better alternative if you want to connect to multiple services is Adium.

Please hold your breathe. I’m about to make a bunch of videos on how OS X works. Installing applications is one of them. Along with maintenance, file-structure, terminal, and so on.

My hosting is just borked until tomorrow. Let me know if there is something you want to learn about and I can make a screencast explaining it.

And to answer your Q. Use iChat. it is already in your applications folder.

yeah, use iChat like thetmle said.

iChat and Adium are both good options.

If you want to learn more about iChat, you can watch the video on this page, directly from Apple, or hang out for @johnpowell.

When you install applications you will find them on your hard drive, in a folder called Applications. Either double-click on your Macintosh HD icon on your desktop (if it’s showing) or click on the blue happy Mac face in your dock (at the bottom of your screen.) That will open a Finder window. From there you’ll see a shortcut to your Applications folder in the left sidebar.

I would also recommend using iChat, which is preinstalled on your Mac, or download and install Adium if you use multiple services like AIM, Gmail and MSN.

Thanks for your help everyone, I’ve been using iChat and am getting used to it…it will just take time!
