Has anyone installed yosemite for macbook retina mid 2012 ? How does it run ? Any lag when browsing safari ? How is the smoothness in general compared to mountain lion or mavericks ?
Have you been able to get handoff to work ? I can't seem to "pair" my macbook pro with my iphone 6 with bluetooth . But is "pairing" required for handoff ?Mid 2012 rMBP here. In general the UI is a little bit more sluggish than Mavericks. Mission control is very smooth, but Preview in Finder is noticeable laggy. Safari works great and very smooth. The Preview in Finder issue is the worst case of laggy animation I've seen, but you kind of stop noticing it after a while.
