Downloads
In order to connect to the network you will need to install a supported version of AIM. Windows installers should still work on every version of Windows, even Windows 11. macOS support is provided using WineskinServer, a wrapper for Windows executables. Installation is as easy as opening the downloaded ZIP file and running the application inside.
NOTE: the macOS install is currently showing up as "corrupted", when actually it's macOS quarantining the executable. You can run xattr -d com.apple.quarantine ~/Downloads/AIM35.app to remove the quarantine. I'm looking for ways to avoid that and make usage more streamlined.
