OSX users can follow by Nicolay77 or mikkom that uses the mdbtools utility. You can install it via Homebrew. Just have your homebrew installed and then go
$ homebrew install mdbtools
Then create one of the scripts described by the guys and use it. I've used mikkom's one, converted all my mdb files into sql.
$ ./to_mysql.sh myfile.mdb > myfile.sql
(which btw contains more than 1 table)
