the latest security update will not finish downloading 2021
I have tried and tried to let the latest security update finish downloading but it always fails. I don't know why. Do I try it in safe mode?
My disk is only half full so I don't understand the problem. My macbook is a later 2015 so I can one more update from apple. I don't know if I should just wait for the next system upgrade? I have an antivirus already.
I am concerned bc hackers found a vulnerability in iOS and possibly used this to install Pegasus. I only found out about this bc my antivirus sent me a message, not bc Apple sent it. Now the fix won't install.
I can navigate this system but I'm not an expert at it so is there something simple I can do at home or must I take this to a physical store and see if the experts can get it for me?
MacBook Pro 13″, macOS 11.5
