[R-SIG-Mac] Get this error message after install "“R” can’t be opened because Apple cannot check it for malicious software."

[Simon Urbanek]

That link is to instructions how to circumvent the check, however, the CRAN R releases are notarized by Apple (i.e. they have been checked by Apple for malicious software), so unless you are sure that you definitely have a release from us circumventing it only enables possible attackers to install illegitimate software on your Mac. So I would strongly recommend following the instruction on the CRAN page to verify the signature of the downloaded package before overriding the Apple security measures.

Cheers,
Simon
