Updates 10.13.4 and 5 to my 2018 iMac have both failed despite several attempts. The update downloads and it attempts to restart but fails leaving a black screen and an arrow cursor top left.
The only way to bring it back to life is to hold down the power button - then it switches off and I need to press and hold again to restart it. The software is then still showing as 10.13.3. I have tried this several times even leaving it overnight to cogitate what it should be doing.
This sounds more like a Microsoft type of problem. Has anyone please got a non-too-technical cure?
