I haven’t found a direct import feature, so I guess converting them to TT or OT would be the way to go. Any experience what the best/most reliable method would be? ---

Hi, The only end user software, I know of, that does that it TransType from FontLab. It is possible to use some command line tool or find a online font converter. ---

Hey Georg (and all). Did some research, tried some apps and found this one here to deliver decent conversions (and contrary to the software from fontlab working flawlessly with the newer versions of OS X – no need for Rosetta): [http://www.fontgear.net/fontxchange.html](http://www.fontgear.net/fontxchange.html) ($99,-- as of this writing)
