Thanks for Paragon engineers, now 9.5.226 is workable in Mavericks. A issue is, I have a usb stick with linux os partition, while copy file to /root, finder will popup ask for password, is that right? seems finder regard the partition's user root as system user root, maybe it makes sense. And another question is about LVM, I didn't try it, but if a disk contains LVM and ext3/4 partitions, ExtFS can support it too?
