Force macbook air (2012) to use only 5ghz wifi of time capsule?

Hello!
Is it possible to force the macbook to use only the 5 ghz band of the time capsule wifi?
Otherwise it is loosing lots of speed while switching between the 2.4 and 5 ghz.
(There are approx. 20 other hotsports using the 2.4 ghz band around here...)
Thx in advance!

I would suggest that you configure the Time Capsule to provide a separate name for the 5 GHz network, and then "point" your MacBook at that network.
Open Macintosh HD > Applications > Utilitiies > AirPort Utility
Click on the Time Capsule icon
Click Edit
Click the Wireless tab the top of the next window
Click Wireless Options at the bottom of the window
Enter a check mark next to 5 GHz Network Name (this will add "5 GHz" to the name of the network)
Click Save
Click Update
Then, make sure that your Mac is set to connect to the "5GHz" network as a priority
Open System Preferences (gear icon on the dock)
Click WiFi on the left
Click Advanced at the lower right
Make sure your 5 GHz network is at the top of the list. If not, drag it there
Click OK
Click Apply

I have used Airport Time Capsule with my iMac for several years. I recently purchased a MacBook Air and when it tried to backup to Time Capsule it couldn't because Time Capsule is full. How can I now use the 3TB Airport Time Capsule to back up both?

I have used Airport Time Capsule with my iMac for a couple years. I recently purchased a MacBook Air and when it tried to backup to Time Capsule it couldn't because Time Capsule is full. How can I now use the 3TB Airport Time Capsule to back up both the iMac and MacBook Air? I don't mind losing earlier backups. I have excluded some items from backing up, but since the Airport Time Capsule is full, I can't even begin to back up the MacBook Air.

On your Mac.......
Open Finder > Applications > Utilities > AirPort Utility
Click on the Time Capsule icon, then click Edit in the smaller window that appears
Click on the Disks tab at the top of the window
Click Erase Disk
On the next window that appears, select the Quick Erase option, then click Erase
The operation will only take a few minutes.
Now you are ready to start new backups of both Macs. Back up one Mac first, then back up the other. Do not try to back up both Macs as the same time.

When I start my MacBook Air, I get a problem report on the Time Capsule 802.11n. When I click Continue, it asks for a password. I don't know what the password is because I didn't set this up. How can I find out what the password is?

I have recently update to the OS Maverik and I use a projector with a mini display port adaptor to my MacBook Air, ever since the only thing that projects is my desktop picture. I cannot get it to project my school work that I need to teach my students.

I just ordered a macbook air today and need to know if the 128gb SSD is enough space. I presently have a macbook pro and am using only 30gb hard drive space so, the apple rep said 128 is enough as I do not load much pictures or gaming etc. Also is i5 ok.

Id choose the I5 yes, depends on what your usage is going to be,
....your question about "128 gig being enough" begs the question for IDEALIZED USE of your macbook AIr
In the case of a Macbook Air with ‘limited’ storage on the SSD, this distinction becomes more important in that in an ever rapidly increasing file-size world, you keep vital large media files, pics, video, PDF collections, music off your SSD and archived on external storage, for sake of the necessary room for your system to have free space to operate, store future applications and general workspace. You should never be put in the position of considering “deleting things” on your macbook SSD in order to ‘make space’.
*Generally, unless you NEED the data at least once every few weeks or once a month,...it really does'nt NEED to be on the SSD of your Macbook Air.
Professionals who create and import very large amounts of data have almost no change in the available space on their computers internal HD because they are constantly archiving data to arrays of external or networked HD.
Or in the case of the consumer this means you keep folders for large imported or created data and you ritually offload and archive this data for safekeeping, not only to safeguard the data in case your macbook has a HD crash, or gets stolen, but importantly in keeping the ‘breathing room’ open for your computer to operate, expand, create files, add applications, for your APPS to create temp files, and for general operation.
Ive got more APPS than any human should have on my 128gig AIR,..(50 or so),....and 10gig of working data, important files etc etc.
Still have 82gig available....... the entire point is that someone shouldnt consider the Air a "storage device" for tons of pics, music, vids, etc.
*Never consider any computer a data storage device at any time under any circumstance, rather a data creation, sending, and manipulation device. Anyone who thinks data is safe on any computer, even copied upon multiple partitions is making a mistake that will, without fail, strike.
For needs of packing around a LOT of "big data" with your Air in its case..., get a nice 1TB HD for $70, or even a 2TB drive not much bigger.
Perfect 2TB HD, very slim, the "little giant" made by Toshiba (have several of these) $119

*This one is the BEST external HD available that money can buy:

I'm looking for a laptop that will last me a couple of years which is why I'm upgrading to SSD without losing performance. I usually game on my Mac so I want a laptop to handle that, handle programs in the background and writing or reading without losing speed, I also need a laptop that has fast boot time.
I will be using the laptop mainly for school and running programs such as iWork and mircrosoft office as well as websurfing and video streaming thanks for any advice.

I hope others pipe in with their comments, but the first suggestion is to visit your local Apple Store and try out the units. Trying them out can make a difference in your decision.
This is how I'd try to make sense of this:
MBP 13 2012:
Solid all-purpose portable at a decent price, and even has a 240GB SSD. If you don't load it with tons to videos, this will more than fit your needs as a student and websurfer. A little heavier than the others here, but it's a solid package that's stable. Great if you need to use the CD/DVD.
MBA 13 2012:
Also good, similar specs, notably lighter. Notes are easy to take, and easier to carry on long campus treks. If you're not near a power source, the battery life may be a concern. If you need a CD/DVD, you can connect it when you need it - but it's extra. Servicing a MBA is more difficult.
MBR 15 2012:
Beautiful display, packed with performance. No DVD/CD drive, NVIDIA performance is unproven, kind of pricey, the first generation of a device; it's going to get better over time. Can't be serviced in any way by the user; the Apple Store is your only option. Now's not the best time to get the MBR.
MBR 13 2012:
Same comments.
I'd say the MBA is a good pick. Few moving parts, therefore more reliability. Low heat. You can always attach a CD/DVD drive via USB. Intel Graphics is solid; no problems there. Plenty of capacity for your needs. And the display is bright. MBA 13 or 11, IMO.

How to reset my macbook air 2012?

hi,, my name is jovito ,,i have this macbook air 2012,, and i planning to buy the new version,, and my friend want to buy my 2012 air.. but before he buy this air,, he wants me to reset it first.. and i dont kmow how to.. please help.. thank you...

Before you sell or give away your computer, in addition to the steps mentioned in this support article, take these steps:
Run the Apple Hardware Test or Apple Diagnostics. The buyer will do this (or he should), and you don't want to be surprised by the results.
Reset the PRAM and the SMC, which might contain personal information.
If you set a firmware password, remove it by running Firmware Password Utility in Recovery mode.
If you activated FileVault in OS X 10.7 or later, turn it off.
If you use Boot Camp, the partition must be deleted
If you created any other data partitions on the internal drive, remove them in Disk Utility.
Erase the data partition(s) with the option to zero out data. An SSD doesn't need to be zeroed.
You can't legally or practically transfer any software downloaded from the Mac App Store to the new owner of the machine, even if it was free. That includes OS X, so if you upgraded to OS X 10.7 or later, you must reinstall the original OS, either from the installation media, if applicable, or by booting into Internet Recovery (option-command-R at the startup chime.) If you installed from discs or a read-only USB key, deliver those to the new owner.
The new owner will have to repurchase the software, if need be, under his or her Apple ID. If you ever updated the bundled iLife applications (Garage Band, iMovie, and iPhoto) through the App Store, you can't transfer them either.
Remove the machine from your list of registered products. If it's still covered by an AppleCare Protection Plan, transfer the coverage to the new owner by following the instructions in the AppleCare Terms and Conditions (under the heading "Transfer of Plan.")

Can MacBook Air (2012) handle 1920x1080 resolution on external display?

Hi there,
I was currently thinking about buying the following external display:
http://www.amazon.co.uk/LG-E2251VR-inch-Widescreen-Monitor/dp/B0060LCBTG/ref=cm_ cr_pr_product_top
I have read mixed things about connecting macbooks to external displays so wanted to ask the following:
1. Firstly can the MacBook air 2012 handle an external monitor with resolution 1920 x 1080 @ 60Hz?
2. Secondly, I have heard some Macbooks, with some cables (predominantly HDMI), don't give the option of 1920x1080 when plugged in, instead cap it at around 1600 leaving the external screen blurry. Which connection is best to get the full 1080p resolution, DVI, VGA or HDMI?
Thanks for any help you guys can offer!
Rob

Thanks for your responses!
Captfred - I've tried plugging it into my friends screen now using my minidisplay to HDMI cable and the following options show up:
1080i
1080p
720p
1600x1400
1440x900
etc etc
Is the 1080p option 1920x1080? If I choose the 1080p option, the resolution looks nice and has large real estate on there, the only thing is if I full screen it the top and bottom are cut off? Is this a problem with the aspect ratio of the screen do you think?
Thanks again

Problems with my external USB 3.0 (Toshiba) hard drive and Macbook Air 2012

I can't seem to get any help on this from Apple and I am tired of ti I have a new Macbook Air 2012 model and have several Toshiba external USB 3.0 drives. I did the Mountain Lion App Store 10.8.2 update and all of a sudden non of my drives are mountable or accessible. I've been in IT 16 years and have never seen anything like this. The drives are physically fine and I can see the mapped partitions on a Windows 7 machine just fine and even use HFS Explorer to view the directory structures. The data on these drives is extremely important to not only me, but also the DoD who I am working with on a major project. Now I can't get to my documents to edit them or pull down the virtual machines I setup for my labs.
I've done all sorts of research and googled myself to death. I even foudn the "missing because Apple pulled" 2.0 update to try and fix this issue. Whatever was done with ML 10.8.2 on these notebooks renders the USB ports useless. Does anyone have a solution to getting these drives to mount?

I have the same issue.
I have two disks HDTC720XK3C1 (Portable Toshiba Hard Disk, USB 3.0 + 2.0, 2.0 TB). Purchased on the same date and same model. One inexplicably stopped working.
When i connect the drive, the systems show an message that say:
"You need format the drive <x> before can you use it
Do you want to format it"
I attach the two pictures with the screen error and disk managment.
Question for the group: These devices seem not very reliable ? this type of error the warranty covers? Sugestions ?
i think, that a backup tool should be secure. This is the 7th time I use it and the data is completely lost. Opinions?

Your only option is to sell the one that you have and buy a new one with 8 GB of RAM.

Reinstalling mountain liom on macbook air 2012 takes much time?

Is This normal? Im currently reinstalling os on my secondhand macbook air 2012. It will took almost 2 days. Will this be just fine? Letting the macbook turned on for 2 days? Does this wont overheat the macbook? Or damage its parts?
Or this wont really take 44 hrs. Im also using the wifi connection, my normal download rate is 80-120 kbs/secs in when downloading in safari.
Or what if ill cancel this and connect to another network connection but im also worrying if download stops.

You need to be able to download just over 4 GB. If your connection speed is only 80-120 Kbps, that's quite slow and it will take a long time. Of course, it also may not take quite as long as it's predicting... Early time estimates in things like that can be quite inaccurate.
You should be able to safely cancel and try on a faster network, or you could just leave it running. The latter will not cause the machine to overheat unless the machine has a hardware problem already.

NetInstall MacBook Air 2012

I'm struggling to NetInstall a MacBook Air 2012 and amd looking to the Apple family for help
This is the scenario:
Lion Server running 10.7.4
Download Install Mac OS X Lion.app from App Store (Build 11E53)
Use SIU to create a NetInstall Image
On MacBook Air (Build 11E2702) reboot and hold down "alt" I can see all enabled hosted images
Select the newly created NetInstall Image
MacBook Air fails to boot displaying no entry sign
Now this is where I get confused as everything I've read says that all I need to do is download the lastest version of the Lion Install app and use that create a new image
So what am I doing wrong?
Thanks in advance

Hi
Wireless deployment is not supported with the NetBoot Service. This has always been the case with Apple's own tools. Read the extremely small and informative section entitled "NetBoot and Airport" here:
https://help.apple.com/advancedserveradmin/mac/10.7/#apdF74471B9-9904-4C01-B22F- BF25E01251E7
You may want to consider using DeployStudio as wireless deployment is supported:
http://www.deploystudio.com/Home.html
To give you an idea of performance - I've deployed a 17GB Image to 6 MacBook Airs simultaneously in around 2 hours. The MBAs were placed as close as possible to the nearest 5Ghz enabled WAP for maxmimum bandwidth availability and when nothing else was on the wireless network.
As ever and depending on the quality of the network and the size of image, YMMV.
HTH?

Problems on Mavercks on macbook air 2012

Since i updated my Macbook air 2012 to mavericks i am having some problems, my system freeze sometimes forcing me to restart by pressing the power button for 10 seconds.
Another thing i noticed, its that when i am using graphics aplications, like Final cut or games, me screen glitches a little, if i try to alternate between aplications, make zoom, or this kind of thing, and thats quite annoyng and a little scary, becouse every time look like my system its going to crash.
Id like to know if thats a probem that i can solve by myself, or it is a mavericks problem and apple may fix it in the next updates.
Thanks a Lot

Make sure there's enough free storage space.
Click your Apple menu  top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space.
And try a Safe Mode boot.
Startup your Mac in Safe Mode
A Safe Mode boot takes much longer than a normal boot so be patient.
Once you are in Safe Mode, click Restart from the Apple () menu.

Can I add a second monitor to my MacBook Air notebook and use both monitors simultaneously?

Can I add a second monitor to my MacBook Air notebook and use both monitors simultaneously? For example, have a spreadsheet open on the notebook monitor while the second monitor is displaying an architectural drawing?

MiniDisplay-to-? adapters ... ? replaced by VGA or DVI or HDMI
Best to use only 1 adapter to match the intended cable since mutliple-adapter setup (buy a VGA, then add VGA-DVI adapter) tendsto lose signal strength.
Also graphics chips run hotter driving external display, and since the graphics chip in Air is part of the CPU the CPU may throttle itself as the integrated graphics chip heats up.
Two modes of operation:
Mirror ... same image both displays
Extended ... the other screen is "extra screen space"
