Ok here is my experience with Ubuntu and Macbook Air 6,2.:
Booting live USB:
EFI: 12.04.2 -> without problems
EFI: 13.04 -> without problems
amd64+mac: 12.04.2 -> cannot boot nor recognise Ubuntu USB installer
amd64+mac: 13.04 -> cannot boot nor recognise -||-
with special patch mac_setup.sh from "howto install ubuntu on macbookAir
4,2" (I can provide details) -> booting without using efi is OK with
12.04.2 and 13.04, no difference if "+mac" version or not. (but keep in
mind this bypass and do not use EFI standard way)
Installation from live USB:
12.04.2 -> impossible (freezes when installing grub -> reboot is needed ->
installation is not sucsessfull)
13.04 -> installation works
Booting installed Ubuntu:
12.04.2 -> impossible, because bug in installer (ubiquity?)
13.04 - without acpi=off option in grub -> freeze when booting as aforesaid
13.04 - with acpi=off option -> freeze when booting as aforesaid
13.04 - with nosmp option -> freeze while booting with initramfs shell (saying
something about it could not find SSD with UUID)
13.04 - with nosmp option + with change of root=/dev/sdaX -> first boot usualy
is without problems
-> next boots hangs with SAME settings (only
updated but SAME kernel) at "error: sparse file not allowed" (not serious nor
related bug) or "Loading initial ramdisk" screen (depending on whether you
installed efi or no-efi way).
Usage of vanilla - installed Ubuntu:
13.04 - with nosmp option + with change of root=/dev/sdaX -> strange color
gamut (16bit depth?) + non working wireless.
-> suspend-to-RAM works without problems.
Wireless ( bcm4360 / 43a0 ):
13.04 - with nosmp option + with change of root=/dev/sdaX -> installation of
bcmwl-kernel-source from proposed to saucy results in: A) wireless works and
can see SSID of networks (2,4GHz + 5 GHz)
B) cannot keep connection for more than 3 or 4 seconds when is connected to
wireless networks with wpa-psk or wpa 2.
C) wireless networks without security are OK.

Bug description:
Ubuntu fails to properly boot on Macbook Air 2013 6,1
Ubuntu fails to boot the 13.10 live image from usb without specifying
acpi-off as a boot parameter.
After installation is complete the boot process hangs at a purple
screen. Booting into recovery mode shows that the process stops at the
following:
smpboot: Booting Node 0, #1
I've tried 12.04.2, 13.04, and 13.10. I've also tried booting with
kernel ver 3.9.8-030908-generic and the result is the same.
