Hello
How does one reset or change the default Safari user agent in Mojave?
The infö at the post below works well upto High Sierra, but does not work on Mojave as shown below.

Test-MacBook-Pro:~ test$ sudo defaults delete com.apple.Safari CustomUserAgent
2019-02-17 09:07:45.493 defaultss9283:1832129]
Domain (com.apple.Safari) not found.
Defaults have not been changed.
