So I have had an ongoing issue with a faulty fan which was due to go to an apple store last week. Miraculously the issue resolved itself before the appointment, and whilst I was still going to get it checked out, I decided to hold off due to the difficulty in getting to my local store. Typically the issue has returned, but now I have installed Yosemite. I'm guessing that because this is a 'credible' installation (i.e. not a beta downloaded elsewhere :roll eyes I should be fine in receiving help from the guys @ Apple. Has anyone been into a store in the last couple days and had any trouble receiving assistance? It's just a little way for me to head if I get turned away with an 'unsupported' system.
