OSX compatibility issue with "make secrets"

[raghavnauhria]

I'm using a MacBook Pro to run this code. The step make secrets throws this error: sed: 1: "./misc/secrets.yaml": invalid command code . For macOS, lines 13 and 15 in secrets.sh need to be edited as mentioned in this link: [https://stackoverflow.com/questions/19456518/invalid-command-code-despite-escaping-periods-using-sed]
