Hmm it looks like maybe the sed behaviour I used is not available on BSD sed

[HimbeersaftLP]

You could install the gnu-sed package from homebrew and replace sed with gsed in the script.

But why are you trying to use this on macOS anyways?

[chenyulun]

Because I want to debug IOS 10.3, which is not supported by Safari on my masOS, and actually macOS has a need to debug lower versions as well

[chenyulun]

But our project can debug ios12 at a minimum; so I went back to download the safari-7614.4.6.11-branch branch

Interesting, I didn't know that, but it seems very fitting for Apple to do such a thing.
I can try to fix the sed command to work on BSD sed.
