Dock on Mac
It is very Apple to hide the dock on Mac and only have it appear when needed. However, when I first enabled the feature to automatically hide and show the Dock on macOS 13 in System Settings, I contemplated turning the feature off immediately for how frustratingly slow it was. Before turning the feature off, I Googled Stack Overflow and found this answer:

Execute these in shell:
defaults write com.apple.dock autohide-delay -int 0 
defaults write com.apple.dock autohide-time-modifier -float 0.4 
killall Dock
You need to have turned on the auto-hiding feature in System Preferences first. To modify, you can always change the delay by values to whatever suits you best.
You now have a dock that hides and reappears faster
To reset:
defaults delete com.apple.dock autohide-delay
defaults delete com.apple.dock autohide-time-modifier
killall Dock
