Macbook Air Intel I5

Hi guys, I've an Android app, planning to release IOS version but don't want to spend money on new Macbook. Thinking of purchasing intel based refurbished laptop, sole purpose is to test few functionality(IOS related) major development and testing will be done on my primary laptop. All I will do is run Xcode and emulator. Can I go for 2017 intel i5 model? Even a little lag will do for me if it does the work!
