Abrir la última ubicación del Finder (pestaña o ventana) con un atajo de teclado

Puedes obtener esas válvulas desde "Finder defaults", está en la primera posición bajo FXRecentFolders clave.

Aquí está el AppleScript (basado en el respuesta de Oliver Joseph Ash ):

on findPathSeparator(theData, theFile)
    set pathSeparator to {0, 0, 0, 1, 1, 0, 0}
    set bytesFound to 0
    set bytesSearched to 0

    try
        read theFile from 0 for 0

        set numIterations to 0

        repeat (get eof theFile) times
            set theId to id of (read theFile from bytesSearched for 1)

            if theId is item (bytesFound + 1) of pathSeparator then
                set bytesFound to bytesFound + 1
            else
                set bytesFound to 0
            end if

            if bytesFound is (count of pathSeparator) then exit repeat

            set bytesSearched to bytesSearched + 1
        end repeat
    on error msg
        msg
    end try

    return bytesSearched - (count of pathSeparator)
end findPathSeparator

on getPathFromData(theData)
    set pathSeparator to {0, 0, 0, 1, 1, 0, 0}

    set theFile to (open for access POSIX file ("/tmp/get_recent_folders") with write permission)

    set eof theFile to 0

    write contents of theData to theFile

    set startPosition to findPathSeparator(theData, theFile)

    try
        read theFile from startPosition for 0

        set thePath to ""

        repeat
            set idList to id of (read theFile for 8)

            if (idList does not end with pathSeparator) then exit repeat

            set theLength to item 1 of idList

            set thePath to thePath & ("/" & (read theFile for theLength as «class utf8»))

            read theFile for (4 - theLength mod 4) mod 4
        end repeat
    on error msg
        msg
    end try

    close access theFile

    return thePath
end getPathFromData

tell application "System Events"
    tell property list file "~/Library/Preferences/com.apple.finder.plist"
        set dataItems to property list item "FXRecentFolders"'s property list items's property list item "file-bookmark"'s value
        set itemNames to property list item "FXRecentFolders"'s property list items's property list item "name"'s value
    end tell
end tell

set lastPath to getPathFromData(item 1 of dataItems)
do shell script "open " & lastPath

Sólo hay que asignar un atajo de teclado global a ese script.
