Update installing - mac freezes while restarting; Problem with safe mode
Hi everyone,
I have two problems.
Firstly, after a long time I wanted to install updates appearing in Apple store: iTunes and security update (2020-002 10.13.6) which require restart. I downloaded them and restart mac but first problem appeared. Restarting started as usual but when it went completely black, mouse cursor has appeared and nothing happened. After 20 minutes of nothing I turned it down with power button. Sadly it's happening all the time, I have tried it like six times yet. I am not able to restart the mac or even shut it down normally. It always freezes with the black screen and mouse cursor (when I press any key it just makes the "error" sound) so I alway have to use power button. Fortunately, the system always works normally after this restart.
Secondly, I wanted to try install it (do restart) in safe mode, but another problem appeared, I am not able to run safe mode (*face palm*). I am holding Shift key while booting but it always run in normal mode (I have tried both Shift keys). I was looking for the solution but I don't have FileVault on (it's off) neither I have firmware password set up. Well, then there should be no problem in starting safe mode...

Can anyone help me with this problems?
