It is a fresh install from Steam with no plug-ins. I have tried both creating and survival and it happens on both. I have started 3 different games with different combinations and they all do the same thing. I can access the inventory and click on the crafting menu. The crafting Menu closes and nothing else happens. Works perfectly on my Windows PC its just my MAC Book Air that it does not like. Is it possible it is a display setting issue. I have also noticed that the character screen overlaps the inventory. I can email you a picture if that would be helpful.
