Hello I'm new to the forum and new to the Mac world, left old windows this Christmas after a 12 year love hate realtionship (it just wasn't working out) and entered the mac world. Took delivery of my new Mac pro (base model). It is great, but for the first week she was silent,, now I can gear the hard drive, is that normal? (Standard hard drive read/write sounds). Peace of mind would be appreciated. Wouldn't ask if she hadn't been so quiet at the start!
