Hey there, do you know if using the guest account in mac os x is really safe? I prefer using it for everyday surfing, supposing my mac is clean after restart. My question is if I am really out of trouble by switching off my mac out of the guest account and thereby deleting all files. Could it happen that - say I visit malicious and infringed websites (facebook?) - cookies, trojans, etc might remain on the system? Thank you for any hint. I haven't found any information on google yet.
