That is terrible. Though, I don't understand why anyone would turn on a "find my Mac" feature that has the potential to wipe your entire hard drive remotely unless you have thorough backups. Time machine is dead easy to use; try pluging in a usb hard drive and it will ask you if you want to use this as a backup drive. Arc is something that anyone on the mac should use as well for backing up priceless pictures and files. It encrypts the files locally and then sends them to your amazon S3 bucket as a backup. Easy and cheap too as you are only charged what you backup at the S3 rate(as of now it's ~0.125/GB/Month +a very small amount for put and get requests).
