How to unblock binary from use because Mac says it is not from identified developer

Question

I have a binary from work that I'm trying to run. I keep getting an error that

“my-binary-amd64” cannot be opened because the developer cannot be verified.

I've looked up solutions online and so far I'm encountering problems. This article for example suggests navigating to your Security & Privacy settings and unlocking the ability to allow changes. I see the prompt for `"my-binary-amd4" was blocked from use because it is not from an identified developer' and then there is an Allow Anyway button but that doesn't do anything. (see image below)

The second suggestion is to find the app on finder and click through some settings. But this is simply a binary, so it doesn't show up in the finder so I can' figure this one out.

Answer 1

The file my-binary-amd64 has a com.apple.quarantine extended attribute. Open a Terminal application window and enter the following command. You need to replace <path to file> with the path to the my-binary-amd64 file.

xattr -dr com.apple.quarantine <path to file>/my-binary-amd64

This should remove the com.apple.quarantine extended attribute. If you do not have ownership of the my-binary-amd64 file, then you will need to precede the above command with a sudo, as shown below.

sudo xattr -dr com.apple.quarantine <path to file>/my-binary-amd64

Using sudo will require a administrator password.

For VSCodium, open a terminal and run:

$ /Applications/VSCodium.app/Contents/MacOS/Electron

Or execute:

$ codesign --sign - --force --deep /Applications/VSCodium.app
$ xattr -d com.apple.quarantine /Applications/VSCodium.app

After this, VSCodium can run up via Spotlight.
