Specs: i7-7700HQ GTX 1080 16GB DDR4 256GB Nvme drive - High Sierra I was able to get Mojave, and High Sierra installed and they experience the same issue. I removed Mojave, and installed High Sierra. Whenever a password prompt appears the loading wheel will appear and the password prompt will be unresponsive for a moment or two then it disappears and able to use it. I believe this is relating to aggressive down-clock of the CPU as I notice that when it downclocks to 1.3GHZ, is when I experience the loading wheel. Anyone else have this issue? submitted by /u/Aeather [link] [comments] [► Source]
