Tried riding last night for the first time using my mac book pro… I started out ok but a few minutes into the ride it would freeze up the body of my rider would disappear along with other riders. It was impossible to ride. I down loaded the app to a windows laptop and it runs perfect, Did a quick ride on the windows laptop last night with no issues and then this morning ran great on the windows laptop. I have a MacBook Pro (13-inch, Late 2011), Intel HD Graphics 3000 384 MB. Is it possible my mac book video card just cant handle Zwift.
