MacBook Air 2013: Graphical issues

Hey,
I'm experience a few graphic gliches on my MacBook Air 2013. There two types of graphical issues:
1. Horizontal stripes for a few seconds

Is it just me or do you also experience those issues?

Still: Macbook Air 2013 Wifi Issues On Wake-Up (And Partial Solution)

I just got my new MBA 13" Mid 2013 last week (updated to Mavericks), and have been having issues with the wifi for a couple days now. Specifically, when I wake my MBA in the morning, it will have disconnected from my home wifi and will not reconnect again. It can see the wifi (and it did ask the WPA2 password after I deleted the network in preferences), but it will not connect due to a "Connection timeout".
I didn't have these issues with my old MBP 13' Early 2011 (also running Mavericks). Also, this only started after I had fully set up my MBA and replaced my MBP, that is, connected it to the external display, hard drive, etc.
Now, it turns out what I have to do is disconnect my external hard drive and reconnect to the network. What kind of architecture makes something like this even possible? And it's not just me, https://discussions.apple.com/message/23423481#23423481 had the same problem: needing to remove a USB device in order to be able to reconnect to his wifi.
This reminds me that with my old MBP, I had an issue where copying large data volumes to external drives via USB would render the wifi connection unusable. So apparently there is something about Macbook architecture that links USB and wifi.
But why does this only occur after a full night of the MBA sleeping? I guess it would have to drop the wifi for energy saving, which it doesn't do right away whenever it goes to sleep?
In any way, this is extremely frustrating. What is the deal with USB and wifi in Macbooks? I really hope Apple can fix this via a software solution, but to be honest, I don't trust them to anymore. I guess for them this is "working as intended".
Cheers
Nate
PS: Please, do not post any links to "troubleshooting steps I may find helpful". I do not, because they were not.

It turns out the MBA doesn't even have to go to sleep for this to happen.
Today i received a new HDD for my time machine backups, so some data transfer was necessary. I made a 600GB backup from my Mac and an external hdd I use for media files, then i started copying another 500 Gb from one external drive to another (USB to USB).
Now in the middle of this transfer (which is rather slow to begin with at around 46 MB/s) my wifi connection just went out. My iPhone, iPad and Windows PC can still connect to my router, but the Mac tells me to "move closer" to it.
It's interesting that my Mac can no longer see any other wifis besides my own, so I guess it's wifi range is somehow impeded by these USB transfers? How does that even work?
At around 50% the data transfer had come to a complete halt, so I interrupted the process. Two seconds after I had ejected AND unplugged both external drives, the MBA could "see again". All visible wifis were listed again and I could connect without problem.
Is there anyone with a similar experience? Is this a hardware defect or an architectural problem? Why have I had these USB/wifi-issues on two Macbook models spaced lmost three years apart?

1. Follow these instructions, or these for OS X 10.9 or later.
2. In the Energy Saver preference pane, uncheck the box marked
Enable Power Nap while on battery power
3. You can also try resetting the SMC.
4. Make sure your system is up to date in Software Update.
5. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Macbook Air 2013

I just got myself a new Macbook Air 2013 and while I realized I couldn't expect the smoothest experience, I never expected this much hassle with it. So many differnet issues. No need to have a sad face about it, though - let's get together and figure out how to make this work! At least we only have one graphics chip to worry about this time around
This is going to be a pretty long post but I figured it's good to have it all in one place. Please correct me if you think this is the wrong way to post these things.
Installing and booting
Booting from a normal 2013.6 USB key works fine, but I couldn't seem to get either GRUB or Syslinux working.
I was able to boot by first installing Arch Linux following the Macbook guide at the wiki (having a separate FAT32 /boot partition). Skip the bootloader installation.
Installing rEFInd from OS X (important!) and installing the EFI stub loader made me able to boot fine.
Separate thread.
Stability problems
This is the big worry for me. Every now and then my system hangs for a brief moment and everything involving net or disk access just hangs there for a while and then it seems to work.
So far it only seems to happen when I run something disk- or CPU-intensive. Also had an occassion when I couldn't start X and just got this repeating all over my screen:
ata1.00: failed command: WRITE FPDMA QUEUED
ata1.00: cmd 61/08:f0:10:8c:c2/00:00:0b:00:00/40 tag 30 ncq 4096 out res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)
ata1.00: status: { DRDY }
On the next attempt it worked fine.
I did SMART short and long tests on my disk and they returned fine:
smartctl -a
There are some messages in my boot that indicate this could be disk and/or ACPI related.
journalctl -b
dmesg
This was on a boot when my NIC was renamed from eth0 to wlp3s0 as noted under Wifi - this should hopefully not be a big deal to fix. Will update when I look more into it.
uname -a:
Linux temperance 3.9.7-1-ARCH #1 SMP PREEMPT Thu Jun 20 22:45:32 CEST 2013 x86_64 GNU/Linux
WiFi
WiFi does not work out of the box. Installing wireless-bcm43142-dkms from AUR made me able to connect to my network. I haven't been able to get it stable yet -interface name changes randomly between wlp3s0 and eth0 between reboots and I get disconnected from my network every 30 minutes or so. Disconnects seem to correlate somewhat with the freezes mentioned above.
Separate thread.
Touchpad
Have only been able to get it to work like a one-button mouse using evdev for now. Looks like an upstream bug.
Separate thread
Audio
In order to get audio, I need to put the following in /etc/asound.conf:
defaults.pcm.card 1
defaults.pcm.device 0
defaults.ctl.card 1
I'm no ALSA pro, but I can only seem to get output from the headphone jack so far - no speakers yet.

While I'm using Ubuntu and not Arch, I wanted to chip in with my experiences.
First, I am happy to tell you that I've found a fix for the ata errors/freezes (which for me were so bad I could hardly install) -- at least I think it's the same or related. I got udevd spitting errors about blkid timing out, and it couldn't find the disks. I found this in a Ubuntu forum -- sadly, I can't find the url now. Anyway, Pass
libata.force=1:noncq
to the linux kernel parameters (in Ubuntu you can add this to /etc/default/grub). This disables NCQ, which according to that post wasn't needed.
YMMV and I am not certain that it doesn't have bad side effects, but for me it made the laptop usable.
Other findings:
My Fn key, and thus delete, page up/down, media keys etc didn't work. That's because the keyboard has a new device id which isn't in usbhid. I added entries like the existing apple keyboards with the new device id (05ac:0291) and after recompiling, it works. I'm pretty sure this is fixable by passing the correct "quirks" flags to the usbhid module, e.g. "quirks=0x05ac:0x0291:0x00001248", but I'm not sure which flags should be set (I have an ISO keyboard layout which is yet another flag).
My sound card doesn't work. Or; i hear no sound at least ;-). After checking in alsamixer, it had two cards, one HDMI with S/PDIF only and one with analog in/out and digital in. I tried passing "index=1" to snd_hda_intel, which makes alsamixer pick up the right card by default. I'm not sure if the problem is that pulseaudio still has the wrong card, or something else.
My wifi works after installing bcmwl from Saucy (i.e. the upcoming Ubuntu 13.10 release), which was a relief because I feared this not being supported.
Sometimes after resuming from suspend, the screen is totally dark -- barely discernible in bright daylight. First I figured this was an issue with lightum (a daemon which monitors the lighting and adjusts keyboard and screen brightness), but after checking /sys/devices/pci0000\:00/0000\:00\:02.0/backlight/acpi_video0/brightness it turns out that when this happens, only the brightness levels 13, 14, and 15 (which is the brightest) have any brighness at all. 12 and under means no backlight. The only "fix" I've found so far is rebooting, which sucks. I hope this will get fixed (I will report a bug on Launchpad next time it happens).
Somewhere I picked up that passing
i915.i915_enable_rc6=1
to the linux parameters enables some great power saving features in the GPU. From modinfo:
i915_enable_rc6:Enable power-saving render C-state 6. Different stages can be selected via bitmask values (0 = disable; 1 = enable rc6; 2 = enable deep rc6; 4 = enable deepest rc6). For example, 3 would enable rc6 and deep rc6, and 7 would enable everything. default: -1 (use per-chip default) (int)
Oh, and if anybody knows how I get my GNU/Linux partition to show up in the Mac boot screen I would be grateful! Right now I have refit installed, which works but I would rather just use the built-in boot manager, which works on the predecessor (MBA 3,2).

My MacBook Air 2013 is 'not compatible with Mac OS X Mountain Lion'

Hi,
I just bought a new MacBook Air 2013 yesterday.
I think there may be some driver issues with it as the graphics seem a little choppy.
I tried redownloading Mac OS X Mountain Lion from the Mac App Store but a message constantly pops up saying that Mac OS X Mountain Lion is not compatible with my computer.
Is anyone else getting this issue?

Wait until the next update, or reinstall it from the recovery partition, which is accessible by pressing the Command and R keys at startup.

MacBook Air 2013 Camera Problems

I have a MacBook Air 2013 and recently, after the most current update my built-in camera not only does not work with Skype but does not work with Facetime or Photobooth either.
Under "Camera" in System Report my camera does not show up. I have rebooted, shutdown and cold-booted, pressed Shift + Alt + Ctrl + Command when booting.
I don't want to do a fresh install of my (brand new) computer all over again just yet. What should I do? Is it a software issue?
It's rather frustrating because I can't Skype or even Facetime my family and resorting to an external webcam is a ridiculous notion for a laptop.
Thanks,
scintoon

Hey dominic23,
Thanks - that update solved the issue of me not being able to use the webcam. However, now my mic does not work as well. I have rebooted a few times (shut down, cold boot) as well as holding the Shift + Alt + Command when powering up.
Is there a fix to this? Apple seriously needs to fool-proof these updates. Or, at least never have any of these problems in Mavericks
Thanks for all your help.

Safari on MacBook Air showing graphics in 16-bit colour

Hi all,
On my MacBook Air system, graphics that appear in Safari show up as this (here's a small sample):
In particular, look at the mirroring under the image... it's streaky, indicative of 32-bit-to-16-bit colour conversion.
Is there a setting on Safari that can force it to display graphics in 32-bit colour? The MacBook Air's Display settings don't offer anything with regards to setting a display depth:
Any technical details about this issue would be most welcome! It's not a problem for me, but it is noticable in some Web pages.
Incidentally, Firefox 8 also does this too, but running apps like OmniGraffle Pro:
shows good colour graphics (32-bit).
Is this something that the graphics controller is doing?! For Safari and Firefox to use different rendering engines and produce the same results in rendering images with 16-bit graphics is rather perplexing!
Or... is this Lion's doing?! I am running Safari 5.1.2 and Firefox 8.0.1 on Lion 10.7.2.
Cheers!
—tonza

I finally found what was going on with my MacBook Air... turns out it has nothing to do with the machine at all. Instead it was because I was using a 3G connection in order to get to the Internet.
My mobile phone provider was using a proxy server which reduced the size of images by re-rendering them on the fly in order to reduce bandwidth on the 3G network! So all those graphics artifacts were caused by my mobile phone provider!
If my MacBook Air uses another Internet connection (like WiFi) on another provider, the problem disappears!

Macbook Air 2013 - Sleep Problem

The new macbook air 2013 13' sometimes goes right back to sleep after 5 seconds from waking up. I was wondering if this was happening to other macbook air users and wondering if I can fix this.
Thanks

Well the strange thing is i had this problem too went to the apple store couple of times and they mentionened twice that they are aware of this problem and it will be fixed in an update......
A month ago i spilled water on my mba and motherboard was replaced funny thing is with my old drive and only motherboard replaced i do not have this problem anymore....therefore i am allmost absolutly sure this was hardware issue.
Apple's got a hand on denying this sort of issues because if they acknowledge you can let your mb replaced for free.... but of course you never know for sure and thats what they know....

IPhone 4s keeps connecting and disconnecting from my new Macbook Air 2013

Ok I've been having this problem, I recently got an 11 inch Macbook Air 2013 and after I try connecting my iPhone 4s it keeps connecting and disconnecting every 1-2 seconds. I already check the community, I know this subject has been asked many times. Nothing worked out though. My cable cord must be fine because it works perfectly on my PC. I updated the OS and iOS to their latest firmware and still nothing. Whenever I try opening iTunes I get this message saying " iTunes could not connect to this iPhone. This device is no longer connected. " Please if anyone fixed this issue I would appreciate some help. Thanks in advance.

I just solved it, I hope this helps everyone who is experiencing the same problem. Apparently the iPhone seems to charge normally and connect to iTunes if the iPhone battery is over 60%-70%. This must be a power issue the MBA has.

"Insufficient Space" error preventing app download from App Store for MacBook Air 2013

Hi,
I am using a MacBook Air 2013 model with OS 10.9.4 (Mavericks). It has a 120 GB HD with about 17 GB of free space.
I am unable to download from the Mac App Store as I get an 'insufficient space available" error whenever I try to purchase a larger App (> 2 GB).
After looking through the forums I can confirm the following:
- Both the Finder and "About This Mac" report that 16.5 GB of space is available.
- I have toggled Time Machine and restarted my computer with it "On" and "Off".
- The application description does not mention needing more space for installation (specifically I am now trying to download BioShock 2 which needs about 9 GB).
I tried to contact Apple Support for the App Store and they informed me it was a hardware issue. I do not have Apple Care and do not think this is a hardware issue so would rather not pay the 20$ for support.
Cheers,

If you're trying to add a large amount of data all at once, and you get an alert of insufficient space, then from the menu bar, select
 ▹ System Preferences... ▹ Time Machine
If the padlock icon is closed, click it to unlock the settings and authenticate. Turn Time Machine OFF, then back ON and close the preference pane. Restart the computer. Test.

[SOLVED] No Audio on Macbook air 2013

Hey all,
Currently I have no sound (either through speakers or headphone jack) on my macbook air 2013.
Card: HDA intel audio controller
Chip: Cirrus logic CS4208
when I boot up alsamixer, it says everything is unmuted and everything is at 100% volume, everything looks like its working fine but still no sound.
Things that I have already done but no effect:
blacklisted snd_intel8x0m (as per ALSA page)
added options snd-hda-intel model=intel-mac-auto to both my sound.conf and modprobe.conf files.
I am running the most up to date version of everything, including kernel version 3.12.8 which is supposed to have out of the box support for the card.
Let me know if you need any other information!
Thanks!

I pretty sure its not that. I use ratpoison as a WM (I like a minimal arrangement for my laptop) which doesn't use pulseaudio. Even when I had Gnome with pulseaudio. I still had the same issue.
So I ran speaker-test -c 2 on my computer and this is the output:

HP 23xi / 25xi compatibility with Macbook Air 2013?

Hi,
I'm looking to buy an external monitor (HP 23xi or 25xi) for my Macbook Air 2013 (10.9.1).
Since the MBA doesn't have a HDMI output, I was wondering if a Mini DisplayPort-to-DVI can be used to connect the external monitor?
I've gone through several forums, and many guys seem to have problems relating to blurry displays on their HP monitors -- when hooked up using DisplayPort-to-HDMI adapters
So, can anyone confirm the compatibility of MBA with the HP monitor, and the adapter used?
Many Thanks
Piyush

Hi Piyush90.
I found information on Apple.com about a "Thunderbolt" connector that enables you to connect your Mac Book Air with other monitors. It doesn't state specifically what monitors it will work with but it looks promising that it will be a viable solution to your question.
I've included a link below to the webpage about Thunderbolt.

Can I change my Macbook Air's Graphics card?

Hello, I'm having a problem with my Macbook Air's graphics card. When i open After Effects CC, it says that i need an approved NVIDIA Graphics. That in other means, should I change my Macbook Air's graphics card? Even some programs requires me an NVidia Graphics or ATI graphics to render the media. This annoys me a lot as i can't render the media out the software!
So, is there any possible way i can customise my Macbook Air's Graphics by changing it or some sort?
Service it? Pay it? Ask the iBox store? Dismantle it myself? Please help!!
Product: Macbook Air (128 GB)
Operating System: OSX Mavericks 10.9.4
Processor: 1.4 GHz Intel Core i5
Graphics: Intel HD 5000 -----------> Needs to be changed!!!
Memory: 4 GB 1600 MHz DDR3
Thanks afterwards! =D

Hi.
Macbook Airs only handle integrated graphics card, and there is no slot on the Motherboard to add one. If you want a discrete graphics card, to use with professional software, you need to go towards an iMac, Mac Pro or 15 inch Macbook Pro Retina. If you do not want to buy a new machine, you could get an older second hand Macbook Pro with a discrete graphics card.
The Macbook air isn't built to use this kind of software.
Thank you for using Apple Support Communities.
All the best,
James

Why can't I update bootcamp software on my Macbook Air 2013?

I'm running windows 8 on my 13" macbook air 2013. Apple sent me a notification of updated bootcamp support software and directions for installation. This web page included a list of the models that are supported by this software and mine is one of them. When I began installing this support software an error message said my computer model isn't supported. I called apple care and they told me it isn't their responsibility to supply windows drivers for people running bootcamp. This sounds fishy and completely wrong. Can someone help, please?

Can you go back and post the web page and actual details (drivers, versions, etc)?
Are you trying to update in Windows and from the Apple Software Update application? manually downloading in Windows? you can use either.
Yes, very fishy. Use to be even worse I think with just how well they are ready to answer and help with Windows on Mac topic.
Use to be the old support pages were to me easy to see and find updates and tech support articles but you can still try there for both your Mac, firmware and model specific, and for Boot Camp.
Also when Mac OS X gets updated, often you download new drivers from within Boot Camp Assistant, too, a 3rd method.
Wasn't clear which method was used.
