Can't Get Anywhere on my Computer!! I have Finals in a Week!!!

The pic that you showed me is correct. Wheel is what used to be admin. on older systems. Did you run disk utilities from the new external boot drive to check the internal drive? If that is what you meant by Mac HD cannot be repaired, then you will need to get your file off of it and onto the external drive. Then you will has to go in and erase the internal drive and reinstall. I would, on the internal drive erase the main drive not just the indented volume. Set it up just as you ddid the external. Then you can transfer you file back. What ever you can download and install,i would do, rather then transferring back. Things like Itunes and Iphoto library I would transfer. You can pick and choose what files to transfer. http://www.icreatemagazine.com/tips/how-to-move-files-and-data-to-a-new-mac-with -migr

Sorry I took so long to answer. I had to do an os install on my external hard drive to check out how to use migration assistant.So here it what I have. First the user name on the external boot drive cannot be the same as it is on the internal drive or it will not work. Now first go open the internal drive to utilities and migration assistant. And click continue. then check to another mac. Inter password for internal drive . Open utilities- migration assistant in external drive. Click continue and check time machine and other drives. Inter password. I had to do it twice. It will calculate the size. Then you can select what to transfer. You will be asked for the user name of the external drive. You will not want to transfer system or application files unless you have something in applications you want. You will not need settings. You can transfer you home users files or pick thru some of them. Hope this helps. Remember if it's something you can replace by re-downloading or reinstalling , don't copy it. If you have copies of apps in the old download folder then just copy that .
