I tried pavucontrol, it works now ...
PulseAudio and kmix can be weird

Just a small tip, but you can install kernel 3.18 by enabling the testing repository. This should improve thunderbolt support even more.

@hrod what did you change to lower your power consumption. Did you disable pstates? My CPU is running at full frequency unless I disable turbo and set /sys/devices/system/cpu/intel_pstate/max_perf_pct to something low
Nothing special. Maybe try kill your wm and run powertop in a free tty to see if there is something causing higher gpu usage than my i3? It might just be brightness idk.
Right now with chrome and 20% brightness: details.

Anyone else experiencing slow wake ups ?
If I try to wake up right after I close the lid, it take about 30 seconds. Otherwise it wakes up in about 2 seconds, that's odd.
I'm using systemd and this happens with both gnome and KDE, so I don't think it's DE related.
Also, sometimes after wake ups the screen seems to turn off after a few seconds of inactivity. See https://bugs.freedesktop.org/show_bug.cgi?id=86105
Any fix ?

Yup, don't ever wake the laptop up, then close the lid again. It will take AGES to come back around
For me, still the worse problem is the terrible IO wait. I watch the IO wait a lot, and it causes such a performance knock its unreal. Its the worse thing about this MBP on Linux.
Can be fixed by turning barrier off, but I'd rather not risk a corrupt hard drive.

just a note: careful with upgrading now, broadcom-wl + linux 3.18 = kernel panic: https://bbs.archlinux.org/viewtopic.php?id=192287&p=1
to restore (use ethernet):
$ aurget -S downgrade
$ downgrade linux linux headers
$ aurget -S broadcom-wl
i selected linux-3.17.6

This is now fixed with the -dkms version (which makes things easier anyways, since it'll rebuild the module automatically on kernel upgrades)
sudo pacman -Rnsc broadcom-wl
packer -S broadcom-wl-dkms
sudo pacman -Syu
reboot

This also seems to be resolved on 3.18.2-2, great

Just wondering if anyone has this issue:
Closing lid (1st time after reboot) - computer properly suspends.
Opening lid - properly resumes no problem
Closing lid (2nd time after reboot) - computer suspends...wait for it... after a couple of seconds (somewhere between 5-20) it wakes while the lid is closed!!
Offline
Yes, I noticed this after 3.18. For me it suspends shortly after waking up again (lid closed).

Yeah, this has been an ongoing issue for some time (long before the 3.18 kernel).

I just upgraded and my idle temp is around the 90s (and I hear my fans running). Anyone else get this? Know what might be the cause?

@sokuban, Could be gpe66 acpi interrupt. Did you install yosemite on your macbook even once? If not, could be something else.
Offline
Nope, no yosemite, I meant I pacman -Syu'd. (Never heard of this bug, but good thing I found out now; I'll hold off from updating OS X then.) I had been holding off on -Syu-ing for a while because of the broadcom bug, so I only managed to get it in now.
I just rebooted and actually I don't see this problem now. After a bit of use I'll let you know if this continues.

Next time run htop. Could of been a runaway if it cleared after a reboot?

@frank604: I had a kworder thread for gpe06 at full load resulting in high temperatures so I disabled it( echo disable > /sys/firmware/acpi/interrupts/gpe06 )
Is it because of OS X? Any chance I could revert it?
Also, when I'm turning the notebook on, half the time( literally, first time works, second not) it's unresponsive. I can't login, can't startx, can't change TTY, noting. No input works and I have to hold the power button to forcibly reboot the machine. And the second time it works with no hangs. It's a new issue, anyone experiencing this or having nay idea why/ how to fix it?

I'm on an mba so it's a little different. First of all, you can't revert the firmware to my knowledge. There is a new update in Yosemite 10.10.2 that fixed gpe66. But for me gpe4e still was a little crazy. As to the black screen, it is called flipping. I added i915 in my mkinitcpio to resolve this, not sure which video card is used on boot for mbp.

How's the sound from the speakers for you guys? I'm aware that you can control the "Bass Speaker" (as named e.g. in alsamixer) separately to make the sound less tinny and trebly, but the speakers still sound much better when used under OS X. I mean, of course laptop speakers sound bad anyway, but there's still a very notable difference in performance between Arch and OS X.

Hey guys, any success using a Thunderbolt storage drive? I've booted the live media on my MacBook, then I've put a second MacBook into Target Disk Mode. I don't see the drive anywhere in
/dev/disk/by-*
. For example, I was hoping to see "Macintosh HD" appear in
/dev/disk/by-label
.

@anssi: speakers sound good for me. I actually like them more in Linux because they are a bit less, uhm, I think 'spacious' would describe it. That's the only( small) difference for me.
From 3.19( no idea if it's the kernels' fault or something else) I am experiencing some problems: the interrupts( discussed above), lower battery life( also reported by one other user in the MacBook Air thread. Anyone else experiencing this? I went from around 6 hours to 4 hours with the same usage) and systemctl-suspend not working at all, but pm-suspend works without any problems.
Unfortunately due to IRL work load, I haven't been able to look into any of the issues.

@regulament: Thanks for your answer mate! Sounds like we have the same "problem" then, only for you it's not a problem! The speakers don't sound that bad on linux, but IMO the "tone" the speakers have on OS X just sound better. Also, I have a triple boot setup and the sound on windows is similar to linux. Your description about more "spacious" sound on OS X sounds accurate though! I'm just looking to find out if it's even possible to make the speakers sound similar like in OS X because that is a tone that I personally highly prefer!
Considering your issue, I personally haven't experienced that with an up-to-date system, but I'm using 3.18 kernel still. Are you using [testing] then? I've only disabled gpe4e and gpe66 and done nothing else to improve the battery life etc. I'm not using suspend since after waking up from it the number in /sys/class/power_supply/BAT0/current_now seems to increase and the battery drains itself faster after that.

I am not using testing. I'll look into the issues once I get some free time.

Anyone else having an issue with the SD reader not being detected? If I boot normally, the hardware device isn't detected but everything works fine if I boot into the fallback initramfs. I'm suspecting that there was a change in default kernel modules within the past few months but I haven't been able to solve it.
Offline
I never use my SD Card Reader, but I put a card in now and it wasn't mounted. Also, the device doesn't seem to be detected(nothing in dmesg output).
What's happening with Linux on this notebook? It worked pretty much great up until a month ago. Now ACPI interrupts( ok, that may be because of OS X), lower battery life and now no SD Card Reader.

My cores idle at about 70 to 80 C and fan isn't audible. Any recommendations to bring these temps down?

It shouldn't be getting that hot by itself, maybe applesmc is not loaded for you, or maybe you have set the fans to manual... See this post, specifically:
Yup applesmc is loaded. /sys/devices/platform/applesmc.768/fan1_manual was set to 1. I set this to "0", ran stress and got the same results as you. So looks like its being controlled by applesmc now.
(Remember if you have the 15", it has two fans )
When I have it on my lap I like to boost the min fan speed (without changing the whole profile to manual) so it's a bit cooler:
echo 3500 | sudo tee /sys/devices/platform/applesmc.768/fan1_min
echo 3500 | sudo tee /sys/devices/platform/applesmc.768/fan2_min
