Whosondephone Posted April 12, 2019 Share Posted April 12, 2019 After failing to get Yosemite working I have had great success installing and running Siera and upgrading to Mojave. I have one minor issue. In the beginning the machine would fail to power off on occasion. That no longer seems to be the case. However it seems to release a serge when powering off. It brings down the USB hub of my DVI switcher. Nothing has been permanently dammaged as of yet. I can bring it back up by unplugging the DVI switcher and the monitor. Can someone shed some light on the issue, or direct my attention. Thanks.
