Hi scottschierer,

Welcome to the Apple Support Communities!

I understand that your computer reaches the login screen but does not load the Desktop after you log in. In this situation, I would recommend working through the troubleshooting steps located in the attached article to help resolve the issue.

Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support

Best regards,

Joe
