trouble with updating 10.13.5 to 10.13.6
I have a late 2017 IMAC, and have made multiple attempts to update High Sierra 10.13.5 up to 10.13.6, but it seems to fail at toward the end up the update cycles. I am wireless connected over my personal wifi. What is the problem?
iMac with Retina 5K display, macOS High Sierra (10.13.5)
