last time i upgrade my MacBookPro(early 2011)

Please give me your advise
excuse me but i can't speak English(
Since you have an older MacBook which came with an earlier operating system on an install disc you could try installing Virtual Box and installing OS X 10.7 or 10.8 onto a virtual machine. Then you can run Aquaria from the virtual box.
I don't have OS X 10.10 to test Aquaria with so I don't know if there's a trick to making Aquaria work on 10.10, this is the best idea I have.
