defaults write com.apple.finder AppleShowAllFiles OFF

Now it doesn’t

tell application "Finder" to get folder ".spring" of home
#Can’t get folder ".spring" of folder "username" of folder "Users" of startup disk  of application "Finder"

I need to copy a file to that location.

Answer 1

I would avoid the Finder in this case if possible. do shell script should be able to do what you want.

tell application "Finder"
    set fileToMove to choose file
    set targetPath to "~/.spring"
    set moveCmd to "mv '" & (POSIX path of fileToMove) & "' " & targetPath
    do shell script moveCmd
end tell
