We've had Mac computer for years with 3 teenagers using it and never have we been hacked. My husband and I ave iPads and iPhones and we've not had any problems with those either. I use a Mac Book Pro have had it since June and no problems either. We also have a Dell Desktop with windows and that things has McAfee, it's always updating and so is Microsoft. It runs slow, locks up and I'd get rid of it but it has all my embroidery software and files on it. The kids aren't allowed to use it at all.
