Hey,

While upgrading the firmware for an mP I suddenly realized that I never bothered to upgrade the firmware on my Late 2013 27' iMac. I am still running the apparently ancient 133.0.0 with SMC 2.15f7

1) Is there any significant improvement updating to the current IM141.0118.B12 ?
2) If yes, should I just download the rom and run it, or should I update 'gradually' via updaters?

I hope that might be the reason for 'screen burns' after updating to HS (no issue in S), but yeah, wishful thinking ;)

Anyway,
Thanks a lot.
George
