I have a mid-2009 MacBook Pro that was running OS X 10.11.6 Started to get a kernel panic error and it would not finish booting up. Would not boot into safe mode either. Went back to my Leopard Install DVDs and did an archive and install—moving my old OS to a different folder. This went fine. Computer boots up great and I have access to all my files. So now I need to get it updated to El Capitan. I put in my Snow Leopard Upgrade DVD and clicked install OS X. About 20-30 minutes into install I get all these errors and it refuses to finish the install. It shows an error log full of lines and lines of statements that I don’t really understand. I tried the Snow Leopard install again with the same result. What should I do? Can I install El Capitan without going to Snow Leopard first. Thanks for any and all help.
