APEndpointAggregate Dialog Box
I have a new MacBook Pro, everything is going great except now I am seeing this dialog box whenever I wake it.
I have to dismiss it four or five times every time. I have read the earlier threadon it (which says it's solved, but it isn't), and also followed the steps to create an aggregate device in Audio/MIDI utility, but the issue remains. Seems a bug to me, I'm just posting it here to flag it.
iMac, macOS Sierra (10.12.3), Upgraded to Sierra
