Mainframe: Configuring tn3270 on Mac OS

Note: Due to limitations of the software, users will be unable to connect to the OSU Mainframe using the tn3270 client for OS versions earlier than Mac OS X.

TN3270 is a 3270 emulator for the Mac OS. This software is needed to connect to the OSU Mainframe and access applications such as Marx and TSO.

This software is available on the OSU Site Licensed Software Downloads page.

Instructions for installing and configuring the Mac OS X client are listed below.

Mac OS X

After downloading the installer from the OSU SLS site, decode the tn3270x_316.hqx with Stuffit Expander if necessary. Double click the resulting "tn3270_X_3.1.6.dmg" file, which will mount the tn3270 disk on your Desktop. Create a folder on your hard drive where you would like to store the application.
