Okay, so my system is a 2011 iMac and it has a 200GB SSD along side the factory 1TB Mac Hard Drive. Since upgrading to Yosemite i've had a load of problems. I cannot install new updates. I've tried to reinstall Yosemite. I've tried to repair permissions from disk utility. Nothing has worked for me yet. I'm really hoping I can find some help on here. I will upload a couple of screen shots, (one taken with my iPhone). The first screen shot is of the login screen. I apologize about it being a little burry but the thing I wanted to show was the weird characters that make up all the letters on the screen. The second screen shot is a terminal window showing permission denied on the updates I'd like to install after running sudo softwareupdate -iva.
