I have the same issue that sunrun has reported. I'm not certain if it's related to sleep but I usually have to restart my MacBook Pro or the performance is too poor to be useable. After restarting I have no issues with the client. OS: High SierraSystem: MacBook Pro 15-inch 2017CPU: 2.9Ghz i7Memory: 19GBGraphics: Intel HD 630 / Radeon Pro 560
