You could still try this : http://www.android.com/filetransfer/ I know it says android file transfer, but it actually is an mtp app as Android these days has dropped mass-storage too. But I have been told the latest OS X update broke it. (I cannot tested it since I do not run/have broken-by-design software/hardware) Otoh you could run an ftp/http server on the device and access things like that. At least http and ftp is something that Apple will not break.
