    Hello,

    A little about my MacPro set up:
    2009 Mac Pro 4,1 with a flash upgrade to 5,1.
    running High Sierra with about 32GB RAM. My boot drive is an SSD. I recently noticed my MacPro will not wake from sleep after installing an MSI RX 570 Graphics card. The card works great up until the point of trying to wake it up. I am forced to do a hard reboot. I did not reset the PRAM or anything yet. Before I installed the RX 570, I was using a GTX 680 flashed for Mac. Anyone have any tips to wake from sleep without having to hard reboot? Thanks!

    What version of high Sierra are you on? Because Polaris GPU’s has an issue where they weren’t waking up from sleep on 10.13.2 and 3 but this issue was resolved with the release of 10.13.4. So if you aren’t already updated to it, do so.

    Hello t8er8,

    I updated from 10.13.3 to 10.13.4 and it worked! That was an easy fix. Thank you for your suggestion!
