A note: this page
https://lists.ubuntu.com/archives/kernel-team/2014-January/037052.html
... claims that there is wakeup bug in ACPI for Haswell machines from
vendor HP. That bug could be the same as this, given that this macbook
11,1 also has a Haswell chipset.
And out of the blue I received an email from someone reading this bug
thread suggesting a potential solution to this issue.
Verbatim:
#####
I googled around and found a solution which worked for me:
echo XHC1 >/proc/acpi/wakeup
To verify the change just type:
cat /proc/acpi/wakeup
And now this machine sleeps until the lid is opened!
You may also need to disable the wakeup of usb devices like this:
for usb in /sys/bus/usb/devices/*/power/wakeup;
do
echo disabled > $usb;
done
#####
I have not tried it yet as I would like to learn more about /proc/acpi/wakeup
So far I haven't found the manual page yet.

Title:
[MacBookPro11,1] Won't suspend twice consecutively
Status in linux package in Ubuntu:
Incomplete
Bug description:
I cannot make a MacBookPro 11,1 suspend. When putting the lid down,
acpi_listen prints:
button/lid LID close
button/lid LID open
... so the lid is signalling correctly. Upon opening, the screensaver
prompt is present, and typing in the password brings me back to the
desktop. Nothing is found in dmesg.
When choosing "suspend" from the top-right power menu, the screen goes
black and shortly lights up again, showing the screensaver login
prompt. Typing in the password brings me back to the desktop as if
nothing had happened.
To remark that the power menu in the System Settings shows sometimes
"Suspend" as greyed out.
