MacOS oh-my-zsh errors fix

After an upgrade to my oh-my-zsh software, I was getting a bunch of errors like the ones below:

[oh-my-zsh] Insecure completion-dependent directories detected:
drwxrwxr-x  3 r00t  admin   96 Aug 19 12:34 /usr/local/share/zsh
drwxrwxr-x  4 r00t  admin  128 Aug 19 12:37 /usr/local/share/zsh/site-functions

[oh-my-zsh] For safety, we will not load completions from these directories until
[oh-my-zsh] you fix their permissions and ownership and restart zsh.
[oh-my-zsh] See the above list for directories with group or other writability.

[oh-my-zsh] To fix your permissions you can do so by disabling
[oh-my-zsh] the write permission of "group" and "others" and making sure that the
[oh-my-zsh] owner of these directories is either root or your current user.
[oh-my-zsh] The following command may help:
[oh-my-zsh]     compaudit | xargs chmod g-w,o-w

[oh-my-zsh] If the above didn't help or you want to skip the verification of
[oh-my-zsh] insecure directories you can set the variable ZSH_DISABLE_COMPFIX to
[oh-my-zsh] "true" before oh-my-zsh is sourced in your zshrc file.

To fix this, I used the ZSH_DISABLE_COMPFIX option. The key to using this one is that it has to be placed before/above the “source $ZSH/” line:

# ZSH_CUSTOM=/path/to/new-custom-folder

# Which plugins would you like to load?
# Standard plugins can be found in $ZSH/plugins/
# Custom plugins may be added to $ZSH_CUSTOM/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.

#Fix errors

source $ZSH/

# User configuration
