Rendering Issues (SC 2013)

[portskydiver 1]

Hi there, i've been digging around EA's website and here and have not come across this problem on either site. Just yesterday my game has been having difficulties rendering most buildings in any city that I try, and I have not been able to find any fix to it.

 

All my buildings appear on the map just fine, on any render settings that I try it on. However, white models of the buildings show up right next to it. It's like the base model of the building on the map, but shows up in an off position...

 

 

I've tried un-installing re-installing, but nothing. If the game settings are on ultra or low, nothing changes the white error buildings.

 

I'm on a Mac (2013 Model), recently updated to the OS Yosemite Beta (And the game was working fine after I updated) but then started acting up a day or two after. 

 

Any ideas?
