IO Error: Os { code: 1, kind: PermissionDenied, message: "Operation not permitted" }

I’m trying to setup a node on my Macbook but get the message in the title when I issue the ./ckb init --chain mainnet command.

Can anyone advise?

Thanks!

Try this:

Click  icon at top left of the menu bar, choose System Preferences -> Security & Privacy, you might find CKB at Allow apps download from: section.

You might want to allow it and then try again, good luck!

Unfortunately I didn’t find any block message for CKB on that screen.

Any other ideas?

it looks like ckb are running in a readonly folder, could you try create a new folder and copy the ckb file to it and run again?
