I have a problem using CVX after I update my Mac OS to Catalina

I have been using the CVX toolbox for 2 years on my mac. However, after updating my mac OS to Catalina I am getting malware error when I try to run CVX.

Catalina’s new security feature. I think this thread

contains an answer by @HMaths with a solution.

after following the steps I could install standard solvers. However, I get this warning
“libcilkrts.5.dylib” is damaged and can’t be opened. You should move it to the Trash.

and I cannot use Mosek. could anyone help me with that?

Does it really say “is damaged” or something else? Can you paste the full error?

Also: here are some much easier tricks which got MOSEK to work on macOS 10.15 for us:

Assuming that it isn’t actually damaged (bad download, bad unpack) then the solutions from MOSEK blog I linked should also help.
