SFS will work fine, depending how your kernel is compiled (should have sfs read/write support) otoh, ext2/3 will work too, there is a ext file system which also has write support on MorphOS, but is considered as beta. So you can choose what you prefer. FFS would work too, but given the known problems with FFS, I wouldn`t recomend that. Problem is Mac OS, afaik there is no filesystemsupport for ext2 or 3 and sure none for sfs. But perhaps there is a way to use the virtual network with samba, so you might be able to share your drives this way. I never tested it, because I found OSX so incredible slow without 3D Hardware support, that I decided to use this diskspace for something more usefull :) Oh and btw, you need some patches to use Tiger with MOL.
