Nope--I had no issues until I upgraded to 10.11.4. I have been hammering it all day in Illustrator, playing music in iTunes, videos on youtube. No issues yet! I doubt that this many people had logic board issues at the same time they upgraded to 10.11.4, but, in my case, I think it was actually a hardware issue that correlated with upgrading. At least I hope so.
Essentially, it's likely worth it to bring your computer to the genius bar to rule out any hardware issues.
453 comments and 19 pages of people with hardware issues... i dont think so
This is a 100% software issue, i had to downgrade to yosemite my mba 2013 and no issues.
Apple with el capitan has developed "metal" the new core graphics, and those deep changes take a time to be stable.
