Process "warmd" keep busy mac after upgrading to macOS 10.14.4 After upgrading my Mac mini to macOS Mojave 10.14.4, every time I restart the computer the process "warmd" keep busy CPU and hard disk for 10-15 minutes, with great "spooling" noise and slowing down all the finder. What's happened? Its a well known bug of the upgrade?
Have a read of the following;

Provisioning OSX and disabling unnecessary services

It has instructions on how to disable warmd. I can not confirm they are still relevant at this stage as I myself am installing the latest OSX as we speak. I will provide more details after that install finishes.

TL;DR

Kill warmd: sudo launchctl kill -9 system/com.apple.warmd

Disable warmd: sudo launchctl disable system/com.apple.warmd
