How to install.
You'll need a terminal, for this:
First, make sure Skype 5 can accept alternative styles, by typing this command in:
defaults write com.skype.skype SKChatStyleVariants YES
Then, add make the directory structure you need to put custom styles where Skype looks for them:
mkdir -p ~/Library/Application\ Support/Skype/ChatStyles/
Then cd to it:
cd ~/Library/Application\ Support/Skype/ChatStyles/
then clone this badboy into that directory:
git clone https://github.com/mrchrisadams/Comic-Sans.SkypeChatStyle.git
Restart Skype, then choose it from Preferences -> Messaging
.
BOOM! See how long you can last before you claw out your own eyes!
