You can set up dual boot with an EFI boot manager such as efibootmgr, refit or refind. First shrink your mac partition with disk utility in Mac OS X or gparted, then use the free space to install Linux. The cleanest way to share data would be to move it to a separate partition which both OSes can mount, although you can mount non-journaled HFS from Linux if you want to avoid doing that.
