Accidentally deleted Airport interface

HELP!
I was surfing the Internet on my Mac yesterday when it suddenly hung on me.
When I restarted the Mac, the Airport symbol on the top right hand corner was grayed out & indicated that "No AirPort card installed".
I followed some instructions online to try to rectify the problem & somehow after trying several methods, I noticed that the Airport interface in System Preferences > Network is no longer there. When I tried to add it in, the only interface options available were Ethernet, Bluetooth DUN, VPN, PPPoE & 6 to 4.
How do I add the Airport interface back in & to get it working again?
Thanks loads!

Unfortunately, the "No AirPort Card Installed" message is almost always an indication that the internal wireless card on the laptop has failed and will need to be replaced.
The fact that you could not locate an AirPort interface when you checked further confirms that this is very likely.
Take the laptop to an Apple Store or Apple servicer to let them take a look and go over your options with you.

Hi, I accidentally deleted wifi cross sign is shown mentioning wifi not configured. What to do now?

Hi, I accidentally deleted the wifi configuration of my macbook air. It shows wifi not configured. What to do now?

Back up all data.
Open the Network pane in System Preferences. A list of available network services appears on the left. If Wi-Fi is in the list, select it, then from the popup menu labeled with a gear icon at the bottom of the list, select
Make Service Active
Click Apply.
If Wi-Fi is not in the service list, click the plus-sign button at the bottom of the list, and then select Wi-Fi from the Interface menu in the sheet that drops down. Click Create, then Apply.
If there is a closed padlock icon in the lower left corner of the preference pane, click it and enter your administrator password to unlock the settings.
If the above steps don't solve the problem, continue.
Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
Right-click or control-click the line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with "com.apple.airport.preferences.plist" selected. Move the selected item to the Trash. You may be prompted for your administrator password. Restart the computer and recreate your settings for Wi-Fi in the Network preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

I tried reinstalling iWork 09 after accidentally deleting it but now it won't open.

I had iWork 09 since I bought my MacBook Pro in 2010. I have version 10.6.8 right now. I accidentally deleted iWork 09 last week and I tried reinstalling it and each time it says "Installation successful". When I try to open Pages, an error message comes up that says, "Pages cannot be opened because of a problem." . I am a college student and everything I have is saved in Pages, therefore I really need to fix this. Help?

The problem may be that all of the prior bits of iWork '09 were not deleted before you tried reinstalling. The iWork installers are very finicky. Deleting everything & reinstalling is probably needed. The files to delete are the iWork ’09 folder from the main HD > Applications; the iWork ’09 folder in HD > Library > Application Support & the individual iWork application plist files found in HD > Users > (your account) > Library > Preferences for each user. Yvan Koenig has written an AppleScript that removes the files. You can find it on his box.com account in for_iWork'09 > other_iWork'09 items > uninstall iWork '09.zip.

Ethernet and Airport Interfaces Reversed

I created an image of the new Mac Book Pro(Mid 2010) and slapped it on the new Mac Mini(Mid 2010) and everything worked fine except one thing. I used the DVD that came with the Mac Book Pro(Mid 2010) to create the Master Image.
Under Network Preferences, the Ethernet Interface is displaying the Airport status window(i.e, "Turn Airport On/Off" button is in there). And the Airport Interface is displaying the Ethernet stats.
Any ideas what could be causing this?

I had the same problem (reversed Ethernet and Airport interfaces) on my 13" MacBook Air after plugging in my Thunderbolt Display. The solution was to go to Network in System Preferences, click the minus symbol under interfaces to delete both of them, click plus to add each one back, then click Apply. Now everything is as it should be.

Accidental deletion of data in contacts application file

While trying to follow instructions from an application web site to correct doubled listing in my contact file, I accidentally deleted the date in the contacts file under applications rather than the contact storage file. (settings/applications/manage applications/contacts. The Droid seems to work OK but I am wondering what I deleted and if I need to take it in and have it somehow restored. Does anyone know what data was in the Contact file?
Thanks

It should just be a simple system file that will not affect the use of the device. However if it does begin to affect the use and operation the device you can always perform a factory reset to clear it back to like new.

Accidentally deleted exchange account and lost contacts....please help

Hello all,
I have a unique problem and I'm worried that it may not be fixable but hopefully it is. Here is the long detailed explanation.
I was trying to start setup for an outlook account to sync my business emails to my phone (which I never got around to doing) I noticed that under mail/contacts etc. that there was an exchange account.....with it being early in the AM and still in bed I accidentally deleted it. I noticed immedietly after that my texts were coming in with numbers rather than contact names. I don't usually use the start mail (blue with white envelope) I had it archived away.....because I have the gmail app which was much more user friendly. Whoever set up the exchange account must have been at the verizon store when i bought the phone possibly. I did not do this myself. Anyways I have a few more problems that makes this issue worse....for some time now my iCloud has been saying it does not have the appropriate amount of storage......(And I assume is not backing up my contacts) I've never really had to use iCloud before so I think this may not help either. I looked on gmail and only certain contacts....older ones were on there. I went to a verizon store and he helped me re-add my exchange account which im assuming was through my gmail email (Only email I really use) and certain contacts seemed to pop up. After leaving the store I realized that a lot of the newer contacts I've added were still missing......I'm not sure what else I can do to recover these contacts if anything but I am now up for suggestion. This is basically where I'm at right now.....not totally missing everything but missing a good deal. Also would like to get my cloud up and running again so this doesn't happen again. I haven't hooked to iTunes yet but I never really did that regularly so that might not help either. Like I said I am up for any suggestion......maybe a way to look up my exchange account if by chance it wasn't under my gmail email account......Thanks in advance!
Sam

How can I access data from accidentally deleted user?

I was given a MacBook Pro by a family member. I set myself as the Administrator, but could not get rid of the previous owner's name on the Home folder.
In my attempts I accidentally deleted something that made the entire computer unaccessable. I can boot up, however, all the work and applications I installed are unaccessable. I can't even open Preferences.
I used TechTool Pro to start up and explore the drive, and found that the previous owner's name was on a folder with a red-circled minus sign. The data (considerable) was inside, but I can't access it.
Is there any way I can get access to that data? I slaved the laptop to my iMac and transferred the folder (with 32 gb of data).
When I tried to open it I got the message: "The folder "sandy....." can't be opend because you don't have permission to see its contents." I used Get Info on the folder and changed Sharing and Permissions to Read and Write, but still no access.
What can I do, if anything to gain access to that folder?

Accidentally deleted bonjour from my computer. iTunes will not open. Help Please.

Accidentally deleted Bonjour from my computer. iTunes will not open. Running Windows XP. Help please.

Uninstalling and then reinstalling your iTunes should also get your Bonjour reinstalled.
For the reinstall, use an installer downloaded from the Apple website:
http://www.apple.com/itunes/download/
... or you could get it back via your Apple Software Update for Windows.
If you'd prefer not to uninstall iTunes, try the following procedure.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the Bonjour.msi (or Bonjour64.msi) to do a standalone Bonjour install.

I just accidentally deleted a video on my iphone 5... Is there a chance I can get it back? If so how?

If you backed up the phone when the video was still on it, restoring the backup will get it back. However, anything new on the phone since the backup will be deleted.

How can I login in to icloud and retrieve a note which I have accidentally deleted on my ipad?

I Have accidentally deleted a note from my ipad and I know it has been backed up yesterday onto icloud but I cant seem to login into icloud to retrieve the note? the icloud.com address just throws up Add Icloud to this device, when I know it is already on it!

You can't use mobile Safari on a device to log into icloud.com. To get to your data, you must use the associated apps. For contacts, use the Contacts app. Only with a computer's browser can you log into icloud.com.

I accidentally deleted Garageband on my MacBook Pro, version 10.6.8. The new version of Garageband is only compatible with 10.9 and above. Is it possible to still get the older version? OR, can I get another copy of the startup CD for my computer

I accidentally deleted GarageBand on my MacBook Pro, version 10.6.8. The new version of GarageBand is only compatible with 10.9 and above. Is it possible to still get the older version? OR, can I get another copy of the startup CD that came with my computer so that I can reinstall GarageBand?

The new version of GarageBand is only compatible with 10.9 and above.
If your Mac can run MacOS X 10.6.8, it probably can be upgraded to Yosemite, if you don't have to stick to Snowleopard for other reasons.
Is it possible to still get the older version?
Amazon or eBay are still selling iLife '11 installer disks, and you could reinstall GarageBand from these DVDs. But it will be expensive.
Have you checked your backups, if you can restore GarageBand from a backup?
OR, can I get another copy of the startup CD that came with my computer so that I can reinstall GarageBand?
Sometimes the AppleStore Support will replace missing installer CDs for a fee.

How can you restore photo stream photos back to Apple TV after accidentally deleting from your iPad

After accidentally deleting photo stream photos on my iPad, this deleted photo stream photos on my Apple TV. How can I restore these photos back to my Apple TV and also to my iPad? Suggestions welcomed

If you have a backup of your iPad prior to the date of deleting your photos, you can find them. Otherwise, you might be able to find them.
If you do have this backup, then you'll have to restore your iPad to that point.
If you had a Mac with iPhoto, then when you connected your iPad, iPhoto would store the photos separately from Photostream.
I despise Photostream. It's turned off everywhere on my system. It is one of the most useless pieces of junk that Apple has foisted on my Mac and iOS. But hey, that's just my opinion.

How can I resend an Apple Store gift card? The email was accidentally deleted.

I was sent an Apple Store (NOT an iTunes) gift card over email, but I must have accidentally deleted it. I know you can resend iTunes gift cards, is there anyway to resend a gift card for the Apple Store?

I know that I can do that. I don't feel like spending any of my money or going and buying another card. I also doubt that im ever going to need more than 50 bucks on itunes. Im asking for a solution that doesnt require much effort, nor money, nor time. Also most stores sell iTunes gift cards, not just apple stores. And I do have a credit card... but thats beside the point.
