Dear Sietse, I run your code and got the following result: === system branch is Darwin: Darwin === cpu branch is x86_64: x86_64 === system: Darwin === cpu: x86_64 === platform: osx-64 It seems to me that the system is OK. But first-setup.sh issues the same error message. After downloading "first-setup.sh" again and try to update again, I'll report the result. Thank you. Best regards, Dalyoung
