Hide Finder on Startup

In Mac, to find the Finder when login. Here is the way.

Create Apple Script as below code and export as Application. Use Login Item to ensure the script run as a usual application.

I also added a 90 seconds delay just in case the Finder is triggered in later.

tell application "System Events"
delay 90 
tell UI element "Finder" of list 1 of process "Dock"
perform action "AXShowMenu"
click the last menu item of menu 1
end tell
end tell
