Q: My laptop's a version 10.5. I've been trying to download the installer for the AIM version for Macintosh. It downloads, but then I try to open it and it says that the operation is not supported. Why does it say this and is there any way I can install AIM on my laptop?
A: AOL stopped making it a while ago so your installer is probably incompatible. Use iChat. It blows the old AIM out of the water and it's already in your Apps folder.
