I’ve read the solution here

Mac 10.15 Catalina: "cannot be opened because the developer cannot be verified"

Dear all, I updated my macbook from Mojave 10.14 to Catalina 10.15.1, then when I want to open the root in the terminal I am facing with message ( “root” cannot be opened because the developer cannot be verified.) could anyone of you help me with this matter please? By the way, I had tried for many time to solve this problem from security&privacy by clicking on “allow anyway” button but, still the problem is remained. Thank you.

but it still keeps throwing the same error for me (developer verification cannot be done)

Here is what I did:

1. cd “location of root”
2. source ./bin/thisroot.sh
3. curl -O https://root.cern/download/nightly/root_v6.18.99.macosx64-10.15-clang110.pkg
4. root

And an error is thrown. Am I doing this correctly? How do I fix this?

Thanks.

@Axel solved the thread you are pointing too. May he can help you with your specific problem.

Just making sure - after curl you did install the package, right? root isn’t going to work out of the box, you need to set it up through . /Application/ROOT-v6.18.99/bin/thisroot.sh (please correct the directory - this is from my unreliable memory).
