There are not quite as many installers for Mac, but I like Etcher. Another solution that offers more legacy support is UNetbootin.
NOTE: USB should be formatted as FAT32 and should have a GUID Partition Table
Do not plug in your USB yet
Open up your terminal and type this:
diskutil list
Take note of which drives are present and insert your USB. Retype:
diskutil list
A new disk should appear. This is your USB, and will be called "/dev/disk" followed by a number. Usually it will be "/dev/disk2", but I will use "/dev/diskN" from now on.
Next we will unmount the drive:
diskutil unmountDisk /dev/diskN
And now to burn the ISO to the USB:
dd if=/path/to/medaid.iso of=/dev/rdiskN bs=1m
Finally we eject our drive:
diskutil eject /dev/diskN
I find that OS X does not handle multiple operating systems very well, so I recommend using the rEFInd boot manager. The installation instructions are on the creator's website.
