I have a mac book air where in when i delete an email the sender ids from all other emails disappears and then again appears in a few seconds.

There is this strange thing happening with my Mac book air.Whwnever i delete a mail fro the inbox or send folder,the sender or receiver ids disappear from all others just to reappear after a few seconds.This started happening after i received a mail enquiring about some products i sell online.i replied to the mail taking it as a legit enquiry.
I did not open any attachment with the mail.Am i been hacked.

Welcome to Apple Discussions
I believe you have a failing GPU (aka Video Card). Run AHT and see what it tells you. Do not be afraid to run it up to three times in succession if at first it does not detect an error (sometimes errors that are caused by overheating will not show up until the computer is stressed enough - repeating AHT will do that).
As an aside - the MBA was not designed to take the place of a desktop. If you are powering your MBA by leaving it permanently attached to the thunderbolt port on the monitor you are shortening your battery life.

I have a mac book air 11". When I boot up connected to the huge Thunderbolt screen it detects the detects the fact and gives me great quality. now I am travelling away from the scree it boots up, nice picture, then switches to rubbish resolution.

I have a Mac Book air 11". Normally at home I connect this to a large Thuderbolt Screen. When booting up it some times gets confused and offers me a low resolution result, but some plugging and unplugging of the screen fixes this. I assume it sometimes "sees" the big screen and sets the resolition accordingly. Sometimes does not. But now... I am away from big screen and cannot get the Macbook air on its one to deliver anything other than really poor resolution. I ahve done displays and chosen all three - but no better. And I have said Choose the Best ONe... again not luck. Any ideas. I read in back posts this was a problem a few years ago.

I have a mac book air. Have had no issues with any virus before but today my safari page keeps directing me to a page which says " cyber crime" posing to be by Cheshire Police AUthority uk metropolitan police.Tells me that I have 24 hours to pay a 100 pounds.Using my ipad I looked it up and it appears to be a very common virus.I am worried about my Mac(relieved at the same time that I am not a cyber criminal
!) so anyway what should I do.I tried to fonce quit and then open safari but only that page keeps opening up.Looking up online their was a suggestion to reset safari, but I am unable to click on the reset safari tab as the pop up for stay on page keeps coming up.i have switched off my lap top now.But am really worried.How can I get rid of it?

It's not a virus. It's a JavaScript scam that only affects your web browser, and only temporarily.
Some of those scam pages can be dismissed very easily. Press command-W to close the tab or window. A huge box will pop up. Press the return key and both the box and the page will close. If that doesn't happen, continue.
From the Safari menu bar, select
Safari ▹ Preferences... ▹ Security
and uncheck the box marked Enable JavaScript. Leave the preferences dialog open.
Close the malicious window or tab.
Re-enable JavaScript and close the preferences dialog.
If the Preferences menu item is grayed out, quit Safari. Force quit if necessary. Relaunch it by holding down the shift key and clicking its icon in the Dock. From the menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
to get rid of any cookies or other data left by the server. Open your Downloads folder and delete anything you don't recognize.

I just purchased a camera packaged with Adobe photoshop Elements 11. I have a mac book air- which does not have a cd drive. The package did not come with a code or anything that would provide me with another way to install photoshop that came with my camera. Is there any other way i can install this on my camera without using the provided cd or buying the software again?

That doesn't help the user with the serial code though.
There has to be some kind of code somewhere within the package. The disk itself does not contain one. You can look here for help with finding your serial number:

Is it okay to upgrade to mversion mavericks? i have a mac book air version 10.8.5 and my safari is not responding..

i have a question is it okay to upgrade to OS mavericks? free upgrade? i have a mac book air version 10.8.5,

Shouldn't be a problem if your Mac can run Mavericks > OS X Mavericks: System Requirements
As for Safari. When you say not responding, do you mean it won't open a window, or it won't load websites, or it won't launch at all?
The more details you provide, the easier to help you.

I have a mac book air. I felt down and I have broken the screen: several white lines on the screen. Do you know if I can only change the screen? Is it expensive?

Welcome to Apple Support Communities
Take your MacBook Air to an Apple Store or reseller to have your display replaced. If you want, you can buy the display yourself and install it, but as you can see, that's expensive > http://www.ifixit.com/MacBook-Parts/MacBook-Air-13-Inch-Mid-2012-Display-Assembl y/IF188-083?utm_source=ifixit_guide&utm_medium=guide_intro&utm_content=required_ items&utm_term=macbook_air_13%22_mid_2012

HT1338 I dont have a mac book air can you install apps like (angry birds, temple run)

I dont have a mac book air. Can you install apps like angry birds and temple run?

Can you install them on what? Those are both iOS apps (meaning they can be installed on iPods, iPhones and iPads), but iOS apps cannot be run on either a Mac or a PC. I believe that there is a Mac version of Angry Birds as well, which is completely separate from the iOS version of Angry Birds.

I bought Mountain LIon but no dmg is downloaded. I can see the invoice from Apple but not the OS I supposed to receive. Is it a bugg?? I have a mac book air. Thanks

I have a Mac Book Air with 10.6.8. Is Montain Lion my only update option? Is it a must do?

You can also get Lion, but personally, I think Mountain lion is what Lion was supposed to be.
In any case, there is absolutely no reason for you to get either one; Snow Leopard is a nice and reliable OS - of course, if you want any of the added features of the newest OS, then you will have to buy and install it.
So, the decision is up to you. Also note: any older PPC apps that still worked on Snow Leopard will no longer work on the new OS - you'd have to purchase upgrades if one is available.

If the Mac came w/system DVDs, you will need to obtain them prior to selling.
You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.
If you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number. Here's a list of links to all of those - http://store.apple.com/Catalog/US/Images/intlstoreroutingpage.html Another resource: International Support Phone #s.

HT4399 I have a Mac Book Air and have purchased individually numbers and pages. I was given an excel file on a thumb drive and cannot open it. Is there a way to open the xcl file in numbers?

I have a MacBook Air, and have purchased individually Numbers and Pages. I was sent an Excel file on a thumb drive but cannot open the file. The message states that the Excel file is encryeted. Is ther any way to open a PC file on my Mac Book Air?
Pat and Bob

Excel does not use the .xcl extension for any of its native file formats? The only files I've ever seen with xcl as the file extension were associated with embedded application code projects.
If this is in fact an Excel file, but an encrypted one, you cannot open it (in excel or any compatible application) without the decryption password.

I have a mac book air where in when i delete an email the sender ids from all other emails disappears and then again appears in a few seconds.
