I have completed the OS X Maverick upgrade, restart etc. but when attempting to update 8 other Apps to X Maverick I get this message:
WE COULD NOT COMPLETE THIS UPDATE
Failed to verify the preflight file. It is not signed by Apple.
Help!

Similar threads solve this problem by either creating a new administrator identity, which allows one to update applications, or changing the keychain prefs to Best attempt. My issue was solved by adding a new admin user, and then updating the apps from the App store using the new identity. Under my orginal user identity the keychain app would crash when I attempted to open Prefs. After creating a new identity and updating the applications (iPhoto, etc) I found I was able to open the keychain Prefs logged into my orginal identity.

When trying to sign in to Face Time, I continually get "Face time Activation" "Could not sign in. Please check your network connection and try again". I am able to access the internet via Safari, so my network connection seems to be working. What am I doing wrong, and how can I access Face Time?

Hey sklingen,
Thanks for the question. I understand you are experiencing issues signing into FAceTime. The following article may help to resolve your issue:
iOS: Troubleshooting FaceTime and iMessage activation

You may also want to reset your network settings:
Settings > General > Reset > Reset Network Settings.
Note: this will delete any network related settings (saved Wi-Fi passwords, etc), it will not erase any content from your device.
Thanks,

Cant open itunes. Get error message CMBlockBufferCopyDataBytes could not be located in the dynamic link library CoreMedia.dll. Anyone know how to fix that?

Cant open itunes. Get error message CMBlockBufferCopyDataBytes could not be located in the dynamic link library CoreMedia.dll. Anyone know how to fix that?

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
The error hints at a similar pattern to those discussed in the first and third boxes of the user tip, suggesting that you've got an outdated .dll file that needs replacing. You should find CoreMedia.dll in the one of the following folders:
C:\Program Files\Common Files\Apple\Mobile Device Support
C:\Program Files (x86)\Common Files\Apple\Mobile Device Support
Delete it and then repair Apple Mobile Device Support from the Programs and Features control panel. If that doesn't work go for the full tear down and rebuild.

Just wanted to update the community on my exciting adventure to fix my ipad;
I made my way over to the Apple Store here in South Florida and had my appointment with the geniuses. No one could figure this sucker out! They did every thing they could think of to the ipad without success. Couldn't even tell me what the problem was. All were very nice about it, of course. I was told to wait a day while they contacted the great and powerful central genius(es) but apparently no one was home there since they never responded to the request for help.
Anyway, I will go back to the Apple Store one more time before I give in to the conclusion that my 3 year old iPad (original) is DOA

blucoast,
Can you please be more detailed? When are you getting this - what is causing it? Any specific tool or while starting Photoshop itself?
Do you see an error number or error code or a report? Can you post that here?

Trying to update apps on iphone and getting error message, there is not enough available local storage to download these items. you can manage your local device storage usage in settings

trying to update apps on iphone and getting error message, there is not enough available local storage to download these items. you can manage your local device storage usage in settings. What am I to do?

The storage you purchased is in the cloud, and doesn't do anything with your pad. Your problem is simply that you have too much content on your pad. Go to settings, general, usage, and it will show you how much space you have avaliable on your pad. If you let the screen sit for a while, all the apps will be displayed, and you can see how much stuff you have associated with each.
You have to no option but to delete some of the content on your pad. Videos, comics, pitcures and some music files use a lot of space. The cloud allows you to leave stuff there, so you can get it when you need it.

I am getting error message "iTunes could not back up the iPhone because the backup was corrupt or not compatible with the iPhone". I have deleted the backup and restarted my computer, but continue to get this error message. What do I need to do now?

I have recently updated my phone and am attempting to sync it. I got the error message "iTunes could not back up the iPhone because the backup was corrupt or not compatible with the iPhone". I deleted the backup, restarted my computer, and even restored the iPhone, but continue to get the same error message. What do I need to do now?

iTunes places the iPhone backup in the following location. Navigate there & delete everything in the backup folder, but not the folder itself. You will have to turn on "Show All Hidden Files & Folders" to see it:
Mac:~/Library/Application Support/MobileSync/Backup/
Windows XP:\Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\
Windows Vista and Windows 7:\Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\

I get a message of "Could not find installation information for this machine." after trying to Reinstall Mac OS X.

I would like to repartition the Main HD to two Partitions but could not do so and keep on getting an error message of "Could not unmount disc.." so I tried choosing the "Macintosh HD" partition and tried Partitioning it but the option is not available. So to my frustration I tried clicking on "Erase" to see whether doing so would allow me to finally partition my HD but still can't. And now since I erased my Macintosh HD partition I could no longer boot to Lion.
Before doing the above steps I downloaded the Lion Recovery Disc Assistant and created an external Recovery HD using an 8GB flash drive. I used this as startup destination by choosing it as boot destination from pressing Option before startup. I tried using Mac OS X Utilities to Reinstall Mac OS X from the external drive but I only get "Could not find installation information for this machine." message. I also tried booting from the Recovery HD partition on the HD but i also get the same message.
I have a new iMac that came with OS X Lion 10.7.
Anybody have idea how to fix this?

Partitioning on-the-fly may fail if the disk is too fragmented. You cannot run Erase for the internal disk as it contains its system components. The same if trying to run Boot Camp in order to create the Windows partition, it may fail if disk is too fragmented.
If I correctly understand what you want, then you must boot from an external disk, therefore copy Lion to a 4 GB (or higher) flash drive, run the installer, and then choose the option to partition the disk, this is done after rebooting into the installer from the external drive. You cannot do that if the Lion installer is on the internal drive as it cannot erase or repartition itself.
If this fails (did you try this?), then perhaps you can try to create a Lion boot flash or DVD by using a non-Apple app called Lion DiskMaker, when ready restart, after chime press option / alt key, then choose to boot from this newly created boot disk or flash drive. This reportedly works OK (tried with an older version of Lion, not recently, was OK). It is better to work with a flash drive, Lion is not optimized to run from optical media.
WARNING: disregarding the method, you MUST always back up your data when repartitioning or installing / reinstalling.
Hope this helps to solve you issue. Before any attempt, backup, backup, backup.

TS1424 Has anyone encountered trouble transferring rented films to their iPhone? I get error message "iTunes could not copy [film name] to the iPhone because the file could not be written"

I have dowloaded a film to rent. Downloads to iTunes without problem. However it does not transfer to my iPhone.
At first it appeared on iTunes as though it should be on my phone (it definately wasn't).
Apple Support sent me film to download again.
Tried to transfer it again tonight and the error message I get is: "iTunes could not copy [film title]Spy to the iPhone because the file could not be written"
Can anyone help ASAP

Two possibilities come to mind.
Check your source hard drive for errors, right-click on the drive holding the library, click Properties, tools, check for errors, scan for and attempt recovery of bad sectors...
Or...
Repair Security Permissions
Right-click on your main iTunes folder and click Properties, then go to the Security tab and click Advanced. If necessary grant your account and SYSTEM full control of this folder, subfolders and files, then tick the option to replace permissions on child objects which will repair permissions throughout the library. This is the XP dialog but Windows 7 shouldn't be too different.
If it won't let you change the permissions use the Owner tab to take ownership from an account with administrator privileges.
