How to wipe clean and test my MacBook?
I'm using a four year old computer and I'd like to get more mileage out of it. Aside from running slow, it works well now with the occasional click or hum that causes concern.
Would it be wise and/or possible 1) to backup my files 2) wipe clean the machine 3) test the hardware, maybe replace the old hard drive (solid state sounds nice!) 4) reinstall Mac OS and 5) transfer only the apps and files that I need in order not to bring over all the detritus and baggage hidden in corners of the old hard drive?
The part that I really need advice on is how to test the hardware and see if I should replace anything to increase the longevity of the machine.
Is this a good question?
