I have the Retina MacBook Pro 13" Haswell. Yes, I applied the EFI Update late last year. Many times, the pinch-to-zoom doesn't work, but four-finger to Mission Control does or double-tap with two fingers works. Sometimes scrolling doesn't work. When two-finger backswipe is used, the whole page freezes and I have to make a new tab. The only way to fix is to close the lid for one second and open it back up. It suddenly fixes itself. Is this a hardware issue or software issue? Any help would be appreciated.
