Yes, I did not change any sleep settings. I'm using everything at the factory defaults for my early 2015 air.
Awesome! Thank you very much Audit13 with confirming factory sleep settings!
Looks to be the same on mba A1466 so far. after an hour lunch and followed by an hour meeting mba woke from sleep as it should.
Would like to test an overnight sleep before reporting final conclusion on this upgrade. So for, this has been a great and easy upgrade!
Only downside I can nitpick now is shipping time for ngff adapter from sintech site.
