When I go to the store it turns all black and nothing happens. I've done everything and it never works. Either it turn all black or it sits there, loading forever. I am using a mac and also have had problems with this on Windows. The store hasn't worked in about a week.
I am having the same problem for about a week as well, some of the store pages never load, occasionally one will randomly work, if I go to buy something, that transaction takes forever, and sometimes just doesn't register at all. However I am using Windows 8.1, not a mac, so I suspect its the store servers that are the problem...
I too tried all the fixes that support.riotgames.com had on on the subject.
