KUBECTL Autocomplete and Aliases: Use the following to enable auto-completion for kubectl on MAC.

ZSH Autocomplete

Run the following on your terminal:

% source <(kubectl completion zsh) 

If you are getting the error:

/dev/fd/11:2: command not found: compdef

You might need to activate the completion system. Run the following on your terminal:

$ autoload -Uz compinit

$ compinit

$ source <(kubectl completion zsh)

$ echo "[[ $commands[kubectl] ]] && source <(kubectl completion zsh)" >> ~/.zshrc

Now you can use tab for auto-completion of kubectl commands. 

Alias

You can create aliases and add them to your ~/.zshrc  file, for example:

alias k="kubectl"

alias kgtkc="kubectl get tkc -A -o"

alias kgp="kubectl get pods"

alias kg="kubectl get"

alias kge="kubectl get events"

alias kd="kubectl describe"

Custom:

columns=NAMESPACE:.metadata.namespace,NAME:.metadata.name,PHASE:status.phase,CREATIONTIME:metadata.creationTimestamp,VERSION:spec.distribution.fullVersion,CP:spec.topology.controlPlane.replicas,WORKER:status.totalWorkerReplicas  --sort-by="metadata.creationTimestamp"'

Adding and saving the above in your ~/.zshrc file, make sure you relaunch the terminal. Now you are ready to use the aliases.
