Windows 8 RTM Final on Macbook Air

If I try to install the Windows 8 RTM Final (from MSDN) on my Macbook Air Mid 2011 using Boot Camp, I get this error:

Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu

I already formatted the disk with NTFS, removed it, reformatted and more...

Does anyone know to resolve this error?

Thank you very much

How can I identify which application is responsible for my battery life being short?

My laptop is getting much shorter battery life than advertised, and obviously that's going to be due to some code running that's draining it faster than is optimal.

How can I (using Mac OSX 10.6) determine which applications are hitting my batteries hardest?

Recording with audio input MacBook Air

I'm trying to record analogue stereo sound with my MacBookAir. The external mic is plugged to the headphones jack, but it is not being shown in the System Preferences. I did a little bit of research, and there is some rumor, that the headphone jack only supports digital-in for mics.

Is there a built-in way to use the analogue stereo sound without purchasing an external converter or a new mic? With my old MacBook 2,1 it was usual for me to do this, but with my new MacBook Air 4,1 it seems to be a tough task.

What is the white thingy that come with the new MacBook Air?

At one point on the MacBook Air specs page there is this photo. It looks like a USB Flash drive, but is described as the "Software Reinstall Drive"? If so, then maybe it is read-only then?

Boot Camp issue - Windows 8 on MacBook

I've installed Windows 8 on my Macbook Air and I'm facing issues with the BootCamp software. On clicking "Boot Camp Control Panel...", i get the following error:

enter image description here

Its a Microsoft Account User and I'm also the Administrator (only user in the System).

I tried creating a new local user account (Standard privileges) and I was able to open the Boot camp control panel.

The reason I have to access this is to change my trackpad settings (such as bottom-right button to right-click, tap to single click).

Can someone help me out on this?

Macbook Air - fonts not aliased on external monitor

I have 2010 Macbook Air 11", which is connected via DisplayPort to HP LP2475w LCD monitor. Unfortunately the text displayed on the external monitor has rough edges and as far as I can tell, it is not anti-aliased at all.

I searched for a solution and the one most commonly offered, such as here, did not work for me. For the record, it says to run this command in the terminal:

defaults -currentHost write -globalDomain AppleFontSmoothing -int 2

Any other options?

"Remote Disk" volume always mounted (but only in Finder)

I just bought a new Macbook Air the other day. Everything is fine except, for some reason my Finder keeps showing the volume "Remote Disk". Now, I assume this is the shared optical drive that is supported on the air.

The problem is I'm not sharing any drives on any other Macs. In fact, it was there as soon as I booted up for the first time. Cmd+I doesn't give me any information about it (it just shows a CD icon) and the drive isn't shown in /Volumes or Disk Utility, nor does it respond to being unmounted.

Does anyone know how I can get rid it?

Which is faster, a new MacBook Air with a 1.8 GHz i7 processor, or a prior-generation MacBook Air with 2.13 GHz Core 2 Duo?

Which is faster, a new MacBook Air with a 1.8 GHz i7 processor, or a prior-generation MacBook Air with 2.13 GHz Core 2 Duo?

I'm wondering if this would be a step down or a step up in speed and processing power. Both have a 256GB hard drive and 4GB of RAM – although I believe there's also a bump to the type of RAM (from 1067 to 1333 MHz) and the graphics card.

This computer is used for programming and development, running IDEs and virtualization when necessary. Gaming isn't important.

How to install Windows 7 on a MacBook Air through Device Sharing from an ISO file?

I am trying to install Windows 7 on a MacBook Air using Boot Camp. I've read that it can be done through Device Sharing with a PC so the Windows 7 DVD will be read in the optical drive of the PC, since the MBA doesn't have one.

I have a laptop that has no optical drive but I have PowerISO so I can mount the Windows 7 ISO on it.

How would I go about installing Windows 7 with this setup?

Can you disable the standby mode on a Macbook Air 2010 model?

It seems that the Macbook Air 2010 model has some issues waking from its standby mode which it goes into after an hour of on-battery sleep. I'm looking for a way to disable this standby behavior. I'm sure there's a plist file somewhere that will turn it off but I can't find it for the life of me. Anyone have any ideas/hints?

Changing USB host controller on MacBook Air from high-speed to full-speed?

Here's my situation; I have a 2011 MacBook Air running Windows 7, and I'm looking for a way to change the USB host controller or hub's speed from high-speed (480Mbps) to full-speed (12Mbps).

I know high-speed is backward compatible, but I need the controller or hub itself to run at full-speed, since I'm testing some 433MHz radio hardware that gets some nasty interference from USB operating at high-speed.

On a regular PC I can access the BIOS and configure the USB hardware there, but on a Mac it's a different story.

Any help is appreciated!

How to move Macintosh bottom dock bar from one screen to another?

On a MacBook Air running OS X Lion, I have a dock bar at the bottom of the built in screen, how can I move this to my external screen? I've already got the menu bar moved, but the screen system preference control does not appear to also control the dock location.

Network Settings per Network

I'm using macbook air with Mavericks. I'm connecting so many wireless network, I could set up TCP/IP settings per network which I connected. How can I do this in Mavericks?

example: I have a router in my home and I want connect this router with manual TCP/IP settings like ip, dns, etc. and I have a router in my office too, but I want connect this router with DHCP. In Linux OSes, network settings setting per network. I'm using Mac OS X now and How can I do that in Mavericks?

Microphone not working on Apple Macbook Air 1,1 (Early 2008; A1237) under Linux

I'm running Linux on the MBA. I can't make the microphone work.

I test using alsamixer and arecord -Dhw -fdat -vv mic.wav together with aplay -Dhw -vv mic.wav

It seems there is a problem with Linux kernel trying to decipher Apple corrupted 'BIOS', in particular the mic pins are not seen/wrongly assigned.

As far as we are concerned here, is there any difference between using rEFIt and BIOS-compatibility mode (see https://wiki.archlinux.org/index.php/MacBook where they claim to have everything working out of the box on mba1,1) and between, say, Ubuntu and Arch?

A nice proposal would be to compile the latest Linux kernel and run hda-jack-retask or a similar patching program, to find the right configuration (in the case of Realtek codec, the missing things I'm supposed to check are either some vendor-specific COEF verbs, EAPD or GPIO setup.), and then come up with a kernel patch to address the issue.

The MAIN PROBLEM here seems the lack of data on how Apple implements and controls the codec, namely whether they have the mic pins as virtual pins, or something else.


Some useful data:

The output from alsa script run as root http://www.alsa-project.org/db/?f=adae8ebee1007043fe83414ac4972319e02255fa

The command hda-jack-sense-test -a (with HP connnected)

Pin 0x14 (Internal Speaker): present = No
Pin 0x15 (Green HP Out): present = Yes
Pin 0x16 (Not connected): present = No
Pin 0x17 (Not connected): present = No
Pin 0x18 (Not connected): present = No
Pin 0x19 (Not connected): present = No
Pin 0x1a (Not connected): present = No
Pin 0x1b (Not connected): present = No
Pin 0x1c (Not connected): present = No
Pin 0x1d (Not connected): present = No
Pin 0x1e (Not connected): present = No
Pin 0x1f (Not connected): present = No

Most likely the chip is Realtek ALC885 (compare also ALC889A) http://guide-images.ifixit.net/igi/bBTSqaeK5JpQ1AWe.large , although at the moment alsa reads it as ALC889A

Takashi Iwai's tutorial https://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio.txt

Some people researched the original files from a running OS X installation on this same model (I think the relevant files are AppleHDA.kext/Contents/MacOS/AppleHDA AppleHDA.kext/Contents/PlugIns/AppleHDAHardwareConfigDriver.kext/Contents/Info.p‌​‌​list AppleHDA.kext/Contents/Resources/layout12.xml.zlib AppleHDA.kext/Contents/Resources/Platforms.xml.zlib) http://www.insanelymac.com/forum/topic/220090-alc889a-pin-configuration/#entry1554954 , even though there seems to be a mismatch with what OS X sees as the mic pins and what happens under Linux (Here help would be mostly required)

Datasheet http://www.realtek.info/pdf/ALC885_1-1.pdf (from the same Realtek, one can also try to download Linux driver, but this is just taken from ALSA project, as stated in the readme file.)

Here for the first time support to audio (except mic) for MBA2,1 (which is morally the same as 1,1) is patched into the kernel http://www.alsa-project.org/pipermail/alsa-devel/2010-February/025511.html

This guys might have done a similar job, though to a more recent version and for sound globally, not just mic: http://blogs.aerys.in/jeanmarc-leroux/2013/09/15/fixing-2013-macbook-air-ubuntu-sound-issue/ and https://bugzilla.kernel.org/show_bug.cgi?id=60811

Note: Mic's the only thing that doesn't work for the MBA1,1 under Linux, while the remaining part of audio works just fine.
