How to format and save designs from my mac to my Jane 9700

[Lindsey Shade Tippets]

I recently purchased a used Janome memory craft 9700.  I got a cf memory card and an ata adapter, I formatted it then tried to use it in my mac but the mac won't recognize the card when it is formatted for the janome, i then formatted it for the mac and the plugged it into the janome and its giving the memory card error and asking if i want to format it.  Has anyone else had this problem? is there a solution for it? I have embrilliance software and have successfully used designs I have saved on the mac and emailed to a friend to put on the memory card but I would like to avoid that step if I can
