Has anyone encountered issues when upgrading an existing Apple Mac computer from macOS Sierra (10.12.16) to macOS High Sierra (10.13) where it doesn't boot into the system volume? After upgrading the SOPHOS Safeguard DE client to ver. 8.00.3.9 and then updating the OS, after several restarts it can't find the startup disk. I have to go into Recovery Mode to manually select the macOS boot volume. Another thing to note, I can't update the computer with the latest macOS update called "macOS High Sierra Supplemental Update". No matter if its through the Apple App Store or manually, it won't install. Any insight would be greatly appreciated!
