Handling Multiple Github Accounts on MacOS

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

Tabs and Windows

Function Shortcut
New Tab + T
Close Tab or Window + W (same as many mac apps)
Go to Tab + Number Key (ie: ⌘2 is 2nd tab)
Go to Split Pane by Direction + Option + Arrow Key
Cycle iTerm Windows + backtick (true of all mac apps and works with desktops/mission control)
