macbook mid 2012 with catalina 10.15.7 crashes for the recent security update 2021-006 10.15.7
Mac book is unable to take the security update
I also have other problem that back up is not taking with new hard drive also
Tried with safe boot and apply security update but the update bar could not progress full night
after force restart - I could see the update has not happened because its still showing in system preferrences
suggestions please welcome
