Thanks! The FileVault2 driver for Linux that you couldn't find is probably this one: https://github.com/libyal/libfvde/wiki https://github.com/libyal/libfvde/w

Thanks! The FileVault2 driver for Linux that you couldn't find is probably this one: https://github.com/libyal/libfvde/wiki https://github.com/libyal/libfvde/wiki It's experimental though. Better back up your data. I'd recommend to create a partition for ZFS and move data there that you want to use on both OSes, or outright install Linux on a zpool and mount that on macOS. This has worked remarkably well for me, even with lz4 compression and all the other great features. Layer ZFS on TrueCrypt if you need encryption, I wrote a howto a while ago but never had the time to update it: https://github.com/zfsonlinux/pkg-zfs/wiki/Dual-booting-OS-X-and-Debian-Jessie-with-ZFS-root,-cross-mounting-and-full-disk-encryption/1e61fbb42b596b528072d199e7b02c9ed3bf2816 https://github.com/zfsonlinux/pkg-zfs/wiki/Dual-booting-OS-X...
