I was installing Homebrew on my MacBook Pro (as per the instructions on this page), when the following message popped up:
git-credential-osxkeychain wants to use your confidential information stored in "github.com" in your keychain.
The authenticity of "git-credential-osxkeychain" cannot be verified. Do you want to allow access to this item?
Always Allow | Deny | Allow
Is it normal for this message to appear while installing Homebrew? Why does it need to use my keychain? What is it going to do with it?
Do I have to click 'Allow' for the installation to complete successfully? What will happen if I don't?
If the answer to the previous question is that I have to click 'Allow', what risks do I run doing so? Is there anything I can do to reduce the risks?
macOS Sierra version 10.12.4
