My Macbook refused to boot, don't know why but took it to my local Apple Store. They tinkered, could not get it to start and did not give me any hope that they could help. "Leave it with us and we will see what we can do." Being out of warranty, only just, I looked for alternate repairers and found Macfixit. Long story short, packed it up, sent it to Melbourne and they returned it, recovered all my data, fixed the problems and got it up and running again with a 6 month warranty on the repair. Happy as. Thank you Macfixit, you saved my bacon. I will certainly be recommending their services to other Mac users. Great job guys.
