I some times get asked if I can fix and work with Apple computers, and the answer is a definite YES. I have been using and fixing Apple Computers for the last twelve years and have seen many changes in the models and components within these machines. Now the components are not always cheap to replace rather like the mac itself but these machines will run for a good 10 years with consistent care and a annual service to keep things sweet. The development of the new generation Imac and Macbook Pro of the retina kind do have me wondering if in the future they will continue to be cost effective to repair after component or user failure.
