Security update does not install #AppleSoftware

 

I got from the App Store a security update (061-64349) for my MacBook Air 7.2 under MacOS 10.13.6. When the download had finished, my Mac tried to start up but got stuck on a black screen. There was a cursor and it moved in response to my trackpad, but nothing else. A forced shutdown was the only way out. I suspected that the download had been corrupted in some way, so I trashed the update files and got a new download. Same problem. I work around it by forcing a shutdown and canceling the "open applications" dialog on startup. Then when the usual "install update" message appears, I postpone it to the next day.? Has anybody seen this before?

Hi

Occasionally when I have troublesome computers startups after an update, I restart in Safe Mode, and retry the update from with Safe Mode.

Have you tried that?

I had not tried this, but I have now. And it makes no difference.
Apple recommends disconnecting all externals, which I have done and makes no difference.
Apple recommends resetting the SMC, after which my MacBook starts up normally, but trying to install the update still gives the same problem.
The internet gives many different solutions to this kind of problem, all without any indication of their effectiveness, which is not encouraging.
I will ask my supplier if they can be of any help.
