macOS Mojave Installation Delay After Upgrade and Logging In


On some devices, after refreshing the device, logging in can lead to the macOS dropping back to an installation process with a suggested insulation duration of around 13 minutes


We have seen several reports on this topic, but we have not experienced this internally.  It is unclear if this is related to particular models of macOS, firmware, etc.

If you experience this and it is of issue to you, then the only course of action would be to raise a support ticket with Apple.
