File dmg damaged on Mac OS [solved]

Hello everyone, I switched to the 11.6.7 operating system on Mac and I can no longer install RT because a message appears telling me that the downloaded file is damaged and cannot be opened. I tried all possible options from the security settings and downloaded the installation dmg file at least ten times.

Hi @carlos1960,

I am not a McPerson, but from where
did you fetch RT?

Have fun!

…from the RT official download page…

I found the solution on the net. You have to open the Terminal, type the following string:

sudo spctl --master-disable

type enter, enter your password, and type enter again. In this way you can install programs not downloaded from the Apple app store.
