This point has been in my mind for some time.Regarding if the time does arrive that my MacBook Air might have to go to a apple store or even sent away for repair. Not long after I had this MacBook I hat to take it to my local apple store for a WiFi fault,as it was then I had nothing much of important on the MacBook. But as time has moved on I have some important private documents and some other info that is also private.what would be the best way to overcome this situation if ever a time comes again that I have to take it to apple repair centre,Some advice would put my mind at rest of what does one do to protect the private items. One reply I had from a friend was to delete all the items on the hdd to an external hdd,that sounds a bit much of a major problem. Any help Please. To put my mind to rest. David.
