The MBA's RAM is soldered onto the mainboard, so you can't upgrade it. You can't even upgrade it from 2GB to 4GB in case you only got the 2GB model.

The Dock is on the bottom screen if the arrangement makes them overlap vertically. Otherwise, it's on the screen with the menu bar, e.g. in the following two arrangements: AFAICT, the reason is that the Dock requires you to move the pointer to the screen edge if it's hiding, and that only works for the bottom-most screen.

Simple Answer: No, and here is why: Macbook Air 11 inch (2010): http://support.apple.com/kb/SP617 Macbook Air 13 inch (2010): http://support.apple.com/kb/SP618 I wish apple was a little more up front about this, but these are the official specs of the new macbook air. Notice how the RAM says "onboard" with a 4GB maximum. This is not upgradable later. ...

You have ControlPersist enabled. My educated guess is that the following happens: You have connection to example.com Logout, but because ControlPersist is enabled, session is kept open for future connections. Something goes wrong with your network connection, and thus, persistent connection breaks. When you run ssh somedude@example.com again, it tries to ...

Download Xcode from http://developer.apple.com (you need a free developer account). It's a newer version anyway. If you have another computer, you can insert the DVD there and copy the installer files across the network, or to an USB disk you can connect to your Macbook Air.

I second @Connor W's suggestion of using Activity Monitor (or "top" from the terminal) to see what's using the most CPU. Unfortunately, that might not show what's using the most GPU, and the GPU has plenty of potential to burn power. Here are some additional battery-saving tips: Make sure you have a Flash blocker installed. I like ClickToFlash. It's ...

Some youtube videos use flash. What I've observed is that when flash websites are running on my macbook, it uses more processing power (because flash is not as efficient as other methods) and gets significantly hotter. When you close them, it cools back down. There has been a lot of controversy with Apple not pre-installing flash on their computers and ...

This question is similar to one previously posted where Kevin Y suggested BetterTouchTool. I found this to work better than MiddleClick. Unfortunately the effect of setting a trackpad event to "Middleclick" has drastically different effects depending on the OS and program. because "Middleclick" has no function in OSX if you want to use it natively, I ...

Go to "Control Panel". Click on the phrase "System and Security". Then "Boot Camp". Click on the "Trackpad" tab. In the "One Finger" area, enable the checkbox next to "Secondary Click". Click OK. This will let you simulate a right click by depressing the bottom-right corner of the trackpad.

Yes, it is read only and it is only for the purpose of restoring your system applications. Here is the Apple support document on it.

Windows Setup will not permit you to install to media other than an IDE or SATA connected hard drive, regardless of what drivers you have. Therefore, it is not possible to install and boot a full Windows 7 environment from an SD card. If you must boot Windows from an SD card, consider using Windows PE, a stripped down version of Windows 7 designed to boot ...

You're thinking of the older first generation Core i7 processors, which used 3 memory channels. The newer second generation ("2010") Core i7 only use 2 memory channels.

You haven't specified price in this equation, which allows for a simplified answer that does not depend on any personal preferences: The new one is faster. Why? The i7 definitely beats the Core 2 Duo (even if the speed seems higher, the i7 delivers much more performance than a C2D) 1333 MHz RAM beats 1067 MHz RAM. You can look at some benchmarks that ...

This Mini DisplayPort to HDMI adapter is available from Apple. You will also need an HDMI cable. Apple offers this one (as well as several others).

I do not think that there is a way without any third party applications. InsomniaX 2.0 that will allow you to control the lid behavior. InsomniaX disables the sleep mode on a Apple Laptop allowing you to play music through speakers while it's closed. Also adds the option to enable hibernation mode. We are currently looking for a new icon set for ...

Sure. The further in it is, the lower the resistance across the connection will be, and if the resistance is too high then there may be a problem with the circuitry on the other side picking up the signal. But 75% should be enough. Yes, provided no solder joints separated and no components were damaged. Thinner PCBs may bend under strain, and some are even ...

I found the answer in the Sublime text forums here: http://www.sublimetext.com/forum/viewtopic.php?f=2&t=4342&p=20036#p20036 This fix worked for me. I did some more digging on this and it turns out it has something to do with how OSX renders fonts for certain LCD monitors. I was experiencing this with my MacBook Air when attached to a Samsung ...

Basically all of them. The default format is PNG, which can be opened in Paint (and probably other default apps) in Windows XP and later. You can change the format to GIF, JPEG, PDF, TIFF, and a few others, all of which are trivially opened on and relatively recent version of Windows (with the possible exception of TIFF, but not by much).

Wheel (middle) click: not available by default. Try MiddleClick, it seems to work on Lion. Wheel scrolling: Two finger scrolling as shown in the video in System Preferences » Trackpad.

You will need a Thunderbolt to DVI adapter. Or, Mini DisplayPort to DVI, since Thunderbolt's display connection is essentially the same as Mini DisplayPort. The Mini DisplayPort to DVI Adapter lets you connect an advanced digital monitor […] to a Mac with a Mini DisplayPort or Thunderbolt port.

It turns out, Windows 8.1 is not currently compatible with the latest Intel HD 5000 drivers! I probably should have mentioned that fact. I was able to fix the issue completely by installing the beta drivers for Windows 8.1, more information here: http://techau.com.au/intel-hd-5000-driver-issues-with-windows-8-1/. I then downloaded the drivers from here: ...

Windows 7 needs about 16–20 GiB (32 and 64 bit, repsectively) in a fresh install. Also remember to leave some space for applications.

Minimum for just install is 20gb for x64 and 16gb for x86. Beyond that the question is what programs do you intend to run. Personally, I find that 60GB is decent if you're frugal with your programs (that's photoshop, a few games, and some project files for C++, etc. in my case). Windows 7 System Requirements 16 GB available hard disk space ...

Assuming the drive works, OWC sells a external drive case called the envoy both as a standalone product and as part of their upgrade kits. Since apple uses a non standard msata varient (See thread on askdifferent and ars technica's article) standard msata adaptors will not work

If your computer boots up at all, it might be possible to use a Thunderbolt cable and target disc mode (http://support.apple.com/kb/PH3838) to transfer your files to another mac. Otherwise, like Journeyman Geek said, your only option is to disassemble the computer with some unusual screwdrivers ...

My MacBook Air mid 2012 with OS X 10.8.3 does have the External Audio-IN capability. It is just bit hidden and not well explained by Big Apple. As you can read it suggest to use the iPhone headset (with microphone. Digging in to that one finds out that it is the audio plug (hardware) that is special. One could be stubborn in wanting to use your ...

You can move the dock with the menubar from the top of the main monitor, if you don't mind that. At the Display Panel, you can drag the menubar and drop it onto the secondary monitor, and you can see the dock has also been moved to the same screen. Just be careful that you click on the menubar not the whole screen! Similar to this tutorial: ...
