Issues with 828k3 Hybrid in Yosemite 10.10.5 @ 88.2/96khz

Checking to see if anyone has had issues with 2x sample rates with this setup. A few months back got a new MacBook Pro Retina, 15" 2.5ghz/discrete graphics. I've been erractically using DP on it with my 828mk3 which I've had for a few years and used with an older computer. Everything was fine until I started using it at 96k and continually got overload issues, MAS shutdowns and one or two other errors. Mind you, this happens on a complete empty project just playing back.

At first I had thought it was a MachFive 3 issue it, then DP/828 when I witnessed it in an empty project then Logic X, then even system audio with Spotify etc. I have no issue on my older Macbook which is significantly less powered so it's not a horsepower issue obviously. This was also with a mostly fresh system without much other software. And even just did a complete wipe/install of the OS and DP/828 and issue still persists ... I then installed Windows 10 via Bootcamp last night, installed DP/MachFive/828 ... no issues at all at 96khz even at 128 buffer. I have to think there is a driver bug in 10.10.5 as my other machine is 10.8.2 and 96k works fine on there. Anyone witness anything here? MOTU tech says they've tested and don't see issues.

Is there anyone who has an 828k3 hybrid and can confirm issues with 2x sample rates on either 10.10.5 or 10.11?
