Hi @amcalabrese29,

Thanks for your message and welcome to our community.

Please kindly check the operating systems supported by TeamViewer and the versions on both devices.

If both operating systems are under support and latest TeamViewer versions are used, please try these steps:

Restart PC on both of device
Uninstall TeamViewer from both devices. Please make sure, to also delete the reg-entries on your computer How do I uninstall TeamViewer on my Mac? 
Download TeamViewer afterward directly from our homepage and install it on the two devices again. Do not use any old Setup.exe. How do I install TeamViewer on MacOS? 

Hope this could help.
