I am wondering this as well.What about battery life? Is it the same as it was under yosemite ?
I'm reading everywhere that el cap reduced battery life, I hope they've fixed that at least in the 11.2 !I am wondering this as well.
I just recently swapped out my HD on my late 2011 15" MBP to a Samsung 850 EVO SSD (cloned the HD to the SSD) and battery hasn't been that great. Almost feels like I had better battery on with HD, although I have read that peeps weren't too impressed with battery on 10.11.1. Wonder if it's improved in .2.
