Interface lags on macbook pro retin 13 late.
The apple forum squeaks on this topic - https://discussions.apple.com/thread/5547471?start...
Question to the owners of this unit, are there any lags? with mission control, swipes?
Or all the same, whether iris or the new OS does not cope with the retina?

Answer 1

Yes, nonsense, I was sitting with a neighbor on the retina, no lags.

Answer 2

20 replies and only ~2000 views and it's called "beeping"? N-yes. I am not the owner of this laptop, but not a word about the interface brakes in any review that I read and looked at. On the contrary, everyone praises him for the smoothness of his work.
