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. ...

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.

Goto Apple > About this Mac > More Info > "Select Software" If "64-bit Kernel and Extensions" says Yes you are running 64bit if No 32bit. If you want to change it see this artical http://support.apple.com/kb/ht3773 Regards

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 ...

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 ...

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: ...

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 ...

The detail in your photo is not that good, but it looks like a printed circuit board (PCB) with an edge connector. The copper contacts of an edge connector are typically called fingers, not "pins", and are often gold plated. The mating (female) connector will typically leave part of the fingers on the PCB exposed, so this is probably what you are ...

You can get something like this USB monitor adapter. Several of my co-workers have two monitors attached to their MBP's. One via the DisplayPort, and one via USB. I only use one monitor myself, so I'm not sure if this is the same one they use. It just happened to be the first one listed on Google.

It's 64-bit. All of the MacBook Air versions use Core 2 Duo processors, which are 64-bit processors. The kernel won't be running in 64-bit mode (as @Mathew's answer showed you how to find out), but that in no way limits you to 32-bit apps. OS X can run each program in a different mode, and tries to run each program in the best possible mode -- many ...

I use Flux which helps me a lot at night. It gives you a somewhat lower brightness and the colors are adjusted according to the light you choose.

The first thing I would check is the Activity Monitor for applications that are running with a high CPU usage. Activity Monitor can be found under /Applications/Utilities/Activity Monitor.app In the app, click the CPU column to filter the processes by CPU usage, and then watch it for a while. If you see one application that regularly uses the CPU a lot ...

Technically, it uses a solid state drive, yes. The main component of a solid state drive is essentially a NAND-based flash memory. So it's basically the same.

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.

Check image for step 13 on iFixit. I wouldn't put my solder iron there...
