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:
- Uninstall TI Connect v4.0 if installed.
- 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.
- Make sure that you do not have a USB cable connected to your computer WHILE installing TI Connect.
- 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.
