Hello, everyone! I have recently bought a MacBook Pro retina 2015 (mjlq2) with i7, 16gb ram and intel iris pro. I like everything about this notebook except one problem that bothers me - the scrolling is pretty choppy in the browsers (both Chrome and Safari). My old Lenovo Yoga 13 runs more smooth than my new 1800$ mac I've tried a clean install sierra and clean install el capitan with the same result. Is my problem because of integrated GPU? Should I change it while I can to the new rMBP 2016 with dedicated card?
