Charlie wants to know if he can make a bootable backup of his hard drive with macOS Big Sur using Carbon Copy Cloner. Leo says he can, but it's not all that easy. Apple has changed the way it does things ... again. It's more secure, sure. But only Apple can sign it. And that means he can't do it anymore without making a clone of the hard drive, installing macOS Big Sur to it, and let Apple sign it. BTW that's how ChromeOS works.
Carbon Copy Cloner
Mike upgraded his computer with an SSD hard drive and after two years, he's getting a drive failure error. SuperDuper said that his hard drive was failing, and won't run. But Crucial, the drive manufacturer says that it isn't and could charge him $500 should they look at it and there's nothing wrong. Leo says it could be a false positive on the part of Super Duper. SuperDuper's SMART technology feature is designed to predict when your drive is going to fail. Problem is, it's not all that smart.
