Fred has a 2008 MacPro Cheesegrater, and he doesn't want to replace it. But it's having kernel panics. What can he do? Leo says a kernel panic is Apple's version of the blue screen of death. And it usually means it has a driver issue or a hardware issue. And sometimes, the first line of the panic will tell you something useful. Bad memory is a common cause of them. Power supply failing is an indicator. Try swapping out single RAM cards. That can tell Fred which RAM is acting up. He could just get one of the latest MacMini's and get a Thunderbolt 3 connection.
