2011 Macbook A1278 not updating past Lion
Hello, I have a 2011 Macbook that I got secondhand from a friend. I was trying to upgrade it to High Sierra since this is the newest OS it supports now. However it says Software is up to date when I try to do it from the Apple symbol. None of the OS's downloads show up in the App store. In fact most things in the App Store only load with a question mark. Things I have done: It had no hard drive so I put a new one in. There are no time machine back ups. Have tried internet downloads of previous OS X software's but they download with no image (just the basic hard drive look) and when I install, it happens very fast and upon restart nothing changes with the OS system. When I redownloaded Lion in recovery mode it shows two hard drives, the one I made "Macbook" and another one that says "Untitled" and that it is locked. Could this be why I can't update? Any suggestions for updating completely?
