It still works, but if you use Yosemite or some other relatively recent options, you may have to jump through some extra hoops. The traditional tool for doing this is rEFIt, but it's been abandoned for five years now.

Many Mac users prefer to use something other than GRUB as the default boot loader, relegating GRUB to secondary status or not using it at all. If you care to do so, you can probably find instructions somewhere on the Internet, but I don't have any URLs handy.

This is definitely fringe/bleeding-edge stuff, so I don't recommend you try it.

GRUB has the ability to boot the OS X kernel directly, but that can be tricky to set up and may lose you some features in OS X. If your Ubuntu installation is in BIOS/CSM/legacy mode, it may be harder, since GRUB can't redirect to an EFI-mode boot. See here for some basic information, although that doesn't give complete instructions for what you want. In any event, you may need to write a custom GRUB entry to get this to boot. It's traditionally stored as /System/Library/CoreServices/boot.efi on the OS X root partition but since Yosemite, it's typically stored on the emergency-boot disk instead, since the root filesystem now uses an LVM setup by default, which the firmware can't read. An EFI-mode GRUB should be able to chainload the OS X boot loader, but the GRUB prober might not know where to find it.
