How I got two computers to update one contribution graph under one github user

Here's what I did to hook up my work computer to attribute commits to my personal Github account.

Assumptions:

If you're following along I'm going to assume you've set up an SSH key to enable pushing / pulling from your second computer.

Dependencies:

A suitable test repo — I cloned my sadiejay/sadiejay repo to test commit and preview the author field.

Documentation:

I then used this blog post to set up my GPG Key.

Github documentation for additional reference.

Steps:

Once I installed the GPG command line tool I followed the prompts.

For macOS, or at least my GPG cli, prompted to input your "Real Name"

I believe "Real Name" corresponds to your Github name NOT username.
For example, my name is Sadie. However, username is sadiejay.

Screenshot of Github name and username

For email use whatever is by your name in your commit history. I made sure to use my no-reply address provided by Githbub. Check note under step 8

And that should work once you generate and input your key into Github.

Help I messed up I didn't change the automatically configured committer info

Incorrectly setup gitconfig

You can edit your gitconfig file with git config --global --edit after you've made a commit on your local computer.

From there you can either

  • git rebase -i and cherry pick which commits needs changing, then git commit --amend --reset if you've pushed to remote

  • git commit --amend --reset author if you haven't pushed to remote.

Updated author -note new commit hash because of rebase

Conclusion + Note

In addition to having the GPG key, having the git config file match the github name and email is the main takeaway, email alone DID NOT work for me on the M1 pro.

I don't know what would happen if I need to change my email to make work email domain.

If I'm missing something or someone can explain what the GPG key is I'm all ears.

This could be all wrong and I just got lucky, but hopefully my lucky instructions help you too 😅
