How to Connect a Ti89 Calculator to Mac Computers using TI-Connect v4.1

Here is a proven way for those of you that struggle to connect your Ti89 calculator to a MAC computer.

This is what you need to do to get connected:

  1. Uninstall TI Connect v4.0 if installed.
  2. Download and Install TI Connect version 4.1  : https://education.ti.com/ticonnect/ticonnectmac41 . Beware: this link immediately downloads the .dmg file to your MAC, there is no webpage loading. Note: that download link may change if TI places the link on a webpage instead.
  3. Make sure that you do not have a USB cable connected to your computer WHILE installing TI Connect.
  4. If Ti89 is not recognized by your MAC: restart the MAC, try the other USB ports, have patience as drivers may take time to load. Listen carefully for sounds signaling successful driver installation.
