I have built a website for a client, which looks fine on my machine and in an emulator, but alas won't load for the client. They said it is fine on windows, but not on a mac, where they seam to be using chrome. Looking at the screenshots, it appears they don't have javascript enabled (the big images come from a scrolling banner and a modernizr check for flexbox appears to not be loading) - yet they assure me Javascript is turned on, and a whatsmybrowser test seems to confirm this. Any ideas?
