Hello!
I have faced the same issue.
The problem is solved in 7.40 starting from Patch level 2 as written in the 2022335 Note.
Base 7.40 Patch 0 doesn't work well on MacBook. I have currently installed the last available now Patch 4 and it seems to be working pretty fine (acceptable at least) on my MacBook Pro 15'' with Retina.
Best wishes,
Anton
