Script to remove all cookies from Safari except for a list of domains

README.md

Installation

First, install CookiesTool to a location of your choice (by default the script looks for ~/bin/CookiesTool).

Then download the script below.

curl --proto "=https" --tlsv1.2 "https://gist.githubusercontent.com/msanders/365b06cbc2f9c63981f4ab88234cd330/raw/safari_clear_cookies" -o /path/to/safari_clear_cookies
chmod u+x /path/to/safari_clear_cookies

To automatically invoke when Safari exits, you can use add this to Hammerspoon:

local eventTable <const> = {
  [hs.application.watcher.terminated] = function()
    hs.task.new(
      os.getenv("HOME")
      ..
      "/.config/hammerspoon/scripts/safari_clear_cookies"
    , nil):start()
  end
}

watcher = hs.application.watcher.new(function(app, event, _)
  if app:bundleID() == "com.apple.Safari" then
    local fn = eventTable[event]
    if fn ~= nil then fn() end
  end
end):start()

Homebrew environment variables can be passed to Hammerspoon via:

launchctl setenv HOMEBREW_PREFIX "$HOMEBREW_PREFIX"

Or via shell config.

Requirements

• jq

brew install jq

Clear Safari Cache

To clear Safari cache, run:

rm -rf "$HOME/Library/Containers/com.apple.Safari/Data/Library/Caches/com.apple.Safari/"
rm -rf "$HOME/Library/Caches/com.apple.Safari/"
