WHen I turn on my macbook it tries to start up then the screen goes black and white typing starts to appear different messages like "bad" and
"corrupt. I can't remember the exact message but, it will go on like this and won't start up anymore. Any help would be appreciated.
Well...........don't worry. This happens due to corruption of Macbook. Mac corruption is a common issue these days. Actually you need a recovery tool to resolve the corruption issue of Macbook and for this, you can use Mac data recovery software which quickly resolve the corruption issue of your Macbook and also recover all your deleted or lost data.
Actually, I have also suffered with this problem so I am sure that it will also solve your problem completely.
