Mac OSX High Sierra 10.13.1 Inconsistent Results

Case One:
I have a Mac Air Book 13" early 2015 running with an Atiko Thunderbolt 2 eGPU and an early titan.

High Sierra 10.13.1 and latest Nividia drivers and cuda: http://www.nvidia.com/download/driverRe … 6538/en-us

Works great!!

If I swap out the titan with a 980 ti I can not get past boot up… just black screen no “bong” or apple logo.

Supported products on nivida does not list 980ti… so that makes sense… but nor does it list the titan : > )))

Has anyone read any compatibility issues with the 980ti and new High Sierra?

Case Two:
Imac 5K- 27" inch late 2015

Same OSX and driver/Atiko t2 situation… but black screen no bong regardless of titan or 980ti, nor with a GTX 285 Mac edition

Welcome any ideas

Thanks

Peter

My MacBook Pro (Retina, 15-inch, Late 2013) becomes very lag after upgraded to 10.13.1, and
If I start Photos, I can’t move mouse cursor.

Today A security update applied,
I try to reinstall all web driver but macosx tell me It’s not compatible …

What can I do?
