I am going to HAVE to update my operating system. I dread it. I know it is going to cause me all kinds of problems, but I'm beginning to be shut out of things. I currently have Mac OS X 10.6.4. Can anyone guide me to a website or thread that will get me through this process as easily possible which will ALSO inform me of what changes to expect and how to keep things as much like they are now as they can be? My work as an online college instructor is all wrapped in this, so I have a very vested interest... Thanks!
