hlafferty28,
My name is Scott, I am a product support specialist on the AutoCAD team and I understand that you are experiencing some freezing behavior in AutoCAD LT 2015 for Mac, I'd be happy to help you with this.
This is a known issue regarding desktop subscription licenses with AutoCAD and AutoCAD LT for 2015, our developers are already working on this issue but they would appreciate it if you could attach a log generated from the Mac from when the freezing behavior occured, I believe you should be able to find these logs in console - view - show log list.
Regards,
Scott
