Downgrade Safari

Alistair_XIII Said:

"Downgrade Safari: I have just downgraded from Catalina from Mojave. Everything is working well except for Safari. The version of Safari from Catalina no longer works on Mojave and it cannot be opened. I am now without a browser on my Mac. The Safari icon has a cross over it and the error message below appears when I click on it. Can anyone help me get a version of Safari back that works on my Mac? Thank you."

2. Then, install your macOS Mojave anew.

3. Finally, migrate it over.
