dj pro Minimum Requirements

I know on the website it officially says supported by any Mac that can run OS X 10.9.

I’m thinking about getting a 2012 MacBook Air with i5 1.7, 128gb ssd, 4gb ram.…

Now I’m new to Mac so be gentle but normally when looking for specs for applications I’d get a min procossor speed & min ram.

Any help & advice please.
