Hi, bought the HDM today and have a few question about some things that I don't understand really. -Disable SIP, can it be enabled again, between times one uses HDM?

During first backup (what does this mean and what can I do if this is some kind of error?): -Volume is marked as dirty. ?? -Detected case-insensitive catalog.??
