I've slowly been converting from PC to Mac. The Mac is awesome and powerful when you know how to use it. I have a few laptops and recently had an issue with one, I restarted it and got a circle with a slash. After an extensive search on how to resolve, I discovered that a safe boot did the trick! Macs are mysterious to me in that I don't know why or how it was fixed. But what if it didn't? In Windows there is something that can check the OS system file integrity (sfc scannow). I want something like that for my Macs. I have found 'file' and 'HD' integrity checks, but I need OS level.
Why must Macs be so mysterious? I want to know more about the OS and be able to tell if I'm going to have/currently having issues. Is there anything out there that I can use to do what I want? I can buy it, I don't care. This system is so cool, I want it ridiculously solid and for me, that means being able to perform OS integrity checks.
