HT6207 Security update made my MacBook Air lose the dock. Help

Once this update occurred, I lost my background and my dock. How can I get them back? Version 10.9.2

I checked both of those items and neither worked. Turn Hiding is not checked, but "position on bottom" is. I've gone to Sys Pref/Desktop & Screen Saver and selected the desired background picture, but once I click it, the background does not change. In fact, each "change" that I request, does not produce a change. If I change my dock to "turn on hiding", and then go out, come back to menu/Dock, the Turn on Hiding is not checked. I've rebooted, I've tried to reinstall the security patch, I've tried to reinstall the operating system and yet, it still doesn't show up a background, or my Dock.

Slow Sleep Wake-Up after Security Update 2014-002 MacBook Air

Hello! I have a 2013 August MacBook Air. I experienced the "screen goes black, hard restart" issue for many months until one of the updates cured that issues, thank goodness. I just updated with Security Update 2014-002 and just noticed it took about 20 seconds for my MacBook Air to wake-up from sleep mode. I was fearful it was back to the "black screen, no wake-up" issue with this update, however when it finally came back up I was relieved albeit very cautious now. Anyone else have this same issue?

Hello macforme
If you are having issues with waking from sleep and slow startup times, then check out the article below. The main thing to try is to reset the SMC and NVRAM as a starting point sort the issue out.

Yosemite made my macbook air slow. Please help.

Hello, my computer has been almost unusable for the past few weeks, I'm quite sure since I installed Yosemite. I read on another thread that I should run EtreCheck and start my own discussion. Here are the results, please help
Problem description:
I installed Yosemite and now my computer is crawling, the fan goes on for long periods and gets overheated. My hard drive was full but I migrated many of my files to dropbox and made sure to only selective sync files that were necessary on a regular basis.

What version of OS X are you using? If Yosemite, you need to update to 10.10.1 or higher.
In any case, start by going to the editor preferences>general, clicking this button and restarting the editor:

Insert the install disk and press c on startup. Select your langauge then, if there's a menubar click utilities then click Disk Utility. If you didn't see the menubar continue with the installer until you see it.
Once in disk utitly select the drive and repair permissions.
After the repair is done, quit the utiltiy.
You can try to reboot and see if it works if you reboot, but if it doesn't repeat the same as before again.
Now you can continue with the installer and install the os.
Quit

I have downloaded the updates on my macbook air but when i restart my computer it says can not install updates due to an unexpected error????

i have downloaded the updates for my macbook air and when i restart the computer it says that they can not be installed because and error occured i have tried 3 times

A common hangup for updates is corrupted file permissions.
Using Disk Utility, perform a Repair Disk Permissions on your main drive, then re-attempt the update.

After I upgraded to Mavericks I was also having this message when I tried to update. There was a previous post about this problem which offered this simple solution which worked for me:

Got it! Thanx. What I did was go to my account, check that they had my new ID and Password which they did, then hit reset button. All fixed.

Generally this is a sign that the iPhone had previously been
hacked/modified/jailbroken and the update relocked it to the
original wireless carrier. If this is the case, only that wireless
carrier can unlock your iPhone. You must contact them to see
if they offer unlocking and if you qualify.
Where did you acquire this iPhone?
What wireless carrier did you use before this problem?
Does the app Cydia appear on your iPhone?
What does it say when you look at Settings=>General=>About=>Carrier?

If I upgrade to Mountian Lion on my iMac, will my Macbook Air get the update free of charge?

I have an iMac and a Macbook Air. Both are running Snow Leopard 1.6.8. If I upgrade my iMac, will my Macbook Air get the update free of charge from the Mac App Store? Is it similar to buying an app on one iDevice and getting it free of charge on another iDevice with the same iTunes account?

Yes, indeed it is the same. But you must use the EXACT SAME Apple ID account on both machines for the Upgrade.
Hope this helps

Updated software on Macbook Air and bootcamp partition disappeared. Windows boot option no longer appears. Can I get it back and the data?

Amy, is there a chance they could both be Syncing to another device that has the data erased?
What are the sizes & modification dates on the files you found?
Could be many things, we should start with this to be safe, though 2 different ones would seem unlikely to be this problem...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

Macbook Air loses connectivity every time it sleeps.

For about a month now my Macbook Air loses connectivity to wifi whenever it goes to sleep. I have it connected to my personal wifi and when I leave the MBA idle it goes to sleep after 15 mins. When I wake the computer it is still connected to my wifi, but the connectivity is gone. I have to turn airport off and then turn it back on. It regains connectivity immediately after that every time. However, it obviously shouldn't do that and it is annoying because it interrupts my downloads. I have tried playing around with the settings and reading the discussion boards. While people have had similar issues, none have been exactly the same and none of the troubleshooting has worked. Wanted to see if anyone had any suggestions or fixes for this. Thanks in advance!

Hello BrettG81,
I know that can be frustrating when your MacBook Air does not maintain a Wi-Fi connection. There are a few things that you can try to get it working again. I know you have done some looking at your settings and possibly some adjustments, but go over the first article as some of the troubleshooting for OS X Snow Leopard and Lion can be helpful. Another troubleshooting option is to create a new network location and test it out to see if you still have the same issue. All the steps are linked below.

I got the new update for my macbook air and know it is saying that i have to pay for pages, numbers, and keynote and it said that it was free before i did the update

I got the new update for my macbook air and know it is saying that i have to pay for pages, numbers, and keynote and it said that it was free before i did the update.Can somebody please help... I need pages for a school report.

If you had the previous version of those apps on your machine then the upgrade is free.
If you didn't have them installed you must purchase them.

Hi, I've been trying to configure my MacBook Air to the iCloud and for the last 3 days it's still uploading my calender. Also a few entries made to the calender in the last few days seem to have gone missing. Is this normal? How long will the upload take?

Since the maximum OS X version for an eMac is 10.5, how are you running OS X 10.7.5 on the eMac?
