Clean up unreachable or orphaned git objects with git prune

Unreachable objects are those that are not accessible by any refs. As an example, say we have made two commits, and reset them to different heads by calling git reset <commit_id> command. Though the git log command will not show the commit info, git still stores it internally as a dangling object.

Find the dangling commit

git fsck --lost-found

Handling Multiple Github Accounts on MacOS

The only way I've succeeded so far is to employ SSH.

Assuming you are new to this like me, first I'd like to share with you that your Mac has a SSH config file in a .ssh directory. The config file is where you draw relations of your SSH keys to each GitHub (or Bitbucket) account, and all your SSH keys generated are saved into .ssh directory by default. You can navigate to it by running cd ~/.ssh within your terminal, open the config file with any editor, and it should look something like this:

Host *
 AddKeysToAgent yes

> UseKeyChain yes
