I have a macbook with OS X. I would like to dive headfirst into linux with gentoo(from a liveUSB). However, I am running into issues with creating the bootable USB in a mac environment. I downloaded the minimal-install-x86 .iso and mounted it to the USB, but I am having difficulty booting the USB.

Forgive my ignorance, but would it work to partition my hard drive and install an easier distro (eg ubuntu), create a bootable USB with the newly made ubuntu environment, then boot and replace ubuntu with gentoo?

Never tried myself, and might be wrong as i don't own OS/X but if you can run chroot, you can just install gentoo from OS/X no liveUSB or anything.
That's something OS/X should be able to do, isn't OS/X BSD base?

It is possible that the ISO does not boot on EFI-only systems like the Mac. You can install Gentoo from any Linux distro, so you can simply choose a different ISO that boots.

undeadplato ... the minimal-install-x86 isn't suitable for USB, it also lacks EFI boot capability, which you will need. As chithanh pointed out most any linux install disk can be used (though again, the same caveats above apply in your case) so look for an image that supports EFI booting and will work without having to format the USB device (so, an isohybrid disk image). Ubuntu iso's, I believe, are isohybrid and support EFI, so one of these should be easily transfered to a USB device on OSX, ie

Code:
# diskutil list # note the "IDENTIFIER" for the USB device
# sudo umount /dev/disk1s1 # or whatever the "IDENTIFIER" of the USB device is
# dd if=/path/to/image.iso of=/dev/disk1s1

Once booted follow the handbook as per the standard install method ... though I'd avoid grub2 and use rEFInd as the bootloader/bootmanager.

Note that the method suggested by krinn won't work as OSX doesn't provide /proc and /sys that would need to be '--bind' in the chroot ... you need to use some form of linux.

@kick6 ... that won't help, Apple's Startup Disk preferences *only* looks for /System/Library/CoreServices/boot.efi on the medium, so it can't be used to boot other efi executables. Also, bootcamp should be avoided for linux (unless, of course, you must use it for tripple boot).

best ... khay
