I ran into some fan issues on my 2012 Macbook Pro and I'm sure its because its been in some pretty dirty places. Had the fan replaced at Apple for $100 but thought it may be time to upgrade. Also it allowed me to give my wife a very nice laptop that is still working in great order. She loves working with photos and thought she would enjoy using a laptop that doesn't limp along.
So this very second my new Macbook Pro (2017) just arrived via UPS so I'm going to save and close this entry so I can open it up and get going.
