Security Update 2020-002 freeze during the restart process

Hello,

I am installing the Security Update 2020-002 on my iMac 18,3 running High Sierra but the upgrade process freeze during the restart process.

During the reboot, I just get a black screen with the pointer displayed and it doesn't go further.

Is anyone facing the same issue ? What is the workaround ?

I still can force the iMac to turn off using the button and when I turn the computer on, it starts as usual. But I can see in App Stores > Updates, that there is a restart expected to finalise.

Thank you for your help or comments.

iMac 27", macOS 10.13

In the Apple Support Community search field enter: High Sierra Security Update 2020-001. You'll get several posts from people who had issues with that piece of junk with some useful advice and workarounds. Once upon a time, I would immediately install an Apple security update. Now, they've become so consistently buggy that I wait at least two weeks and see what the issues are, if any. I've passed on several because of reported issues. Not much point in having the latest security on the Mac, if it doesn't boot. I'm very disappointed at the lack of adequate testing on these updates before releasing them.
