I'm sure that this was asked many times before though I wasn't able to find a satisfying answer.
I don't care that much of PC version since mine has more than enough to get ultra settings on Unity.
Though I'm quite curious about Mac version of the game. I've recently got MacBook Air (2014) model, mainly for work purposes but I'd be glad if it runs Chapters on the decent settings.
So the configuration of my MBA is Intel Core i5 1.4ghz (it is 2 cores low voltage CPU), 4gb of DDR3 Ram, Intel HD 5000, SSD 128gb.
On which type of settings can I expect a descent frame rate with Antialising turned off?

Let's take for example first 3 books.
