When I try to sign on to Mac App Store I get the message "Your device or computer cannot be verified" Yet I can sign on in iTunes no problem. I've tried all the suggestions from App Support but no luck.

What troubleshooting techniques have you tried? Have you restarted the app? Have you restarted your computer?
One idea is to Trash this file; Mac HD/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist and restart.

Can't sign in to Mac app store with known-good ID

I can't sign into the Mac app store from my mini. Everything else works fine (iTunes store, icloud.com) and I can log in to the Mac app store (and everything else too) on my Air. So, it's just the Mac app store and just from my Mac mini.
I rebooted. I deleted the "storeagent" preferences file. I reset the password (to the same one). Still won't work. It just says "unknown error."

Try deleting the cache associated with the App Store.
Open a Finder window. From the menu bar click Go > Go to Folder
Type of copy paste the following:
~/Library/Caches/com.apple.appstore/Cache.db
Click Go then move the Cache.db file to the Trash.
Restart your Mac then try the App Store.

I keep getting an unknown error when trying to connect to the store. I ran diagnostics and it says secure link to itunes store failed.

Please Help

I received this email from Apple and this corrected the problem for me... I only had to reset the iTunes cache
1) Open iTunes
2) At the top menu, click File > Preferences (iTunes > Preferences on a Mac)
3) In the Preferences menu, click the Advanced tab
4) In the Advanced menu, you should see a button that says "Reset Cache". Please click this button.

Why does a document tell me it needs to be opened in newer version of Pages yet when I check the Mac App store I already have it upgraded

I can't seem to open Pages documents and am told "You need a newer version of Pages to open this document" however, I have checked for upgrades in Mac App store and am told all apps are up to date. When I open Pages and check "about Pages" it says I have 4.3. What gives?

It sounds like you already have 2 versions of Pages on your Mac.
Pages 5 is in your Applications folder.
Pages '09/'08 is in your Applications/iWork folder.
You are alternately opening the wrong versions.
Pages '09/'08 can not open Pages 5 files and you will get the warning that you need a newer version.
Pages 5 can open Pages '09 files but may damage/alter them. It can not open Pages '08 files at all.
Once opened and saved in Pages 5 the Pages '09 files can not be opened in Pages '09.
Anything that is saved to iCloud is also converted to Pages 5 files.
All Pages files no matter what version and incompatibility have the same extension .pages.
Pages 5 files are now only compatible with themselves on a very restricted set of hardware, software and Operating Systems and will not transfer correctly on any other server software than iCloud.
Note: Apple has removed over 100 features from Pages 5 and added many bugs:

Archive/trash Pages 5, after exporting all Pages 5 files to Pages '09 or Word .docx, and rate/review it in the App Store, then get back to work.

Dock icons go transparent when clicked, after adding Mac App Store

I just updated my MacBook and got the Mac App Store, which runs perfectly. I downloaded several apps and they also work fine. Now, though, any time I click to open an app on the Dock, the icon disappears as soon as it begins bouncing. It's still there, it has just gone transparent or something. It leaves the space on the Dock and the name appears when I hover over it and everything is normal. There's just empty space where the icon should be. The same thing happens with my four-finger swipe to change applications: the images have disappeared but I can still switch apps and the names still appear. So really, nothing's wrong, it's a cosmetic problem, but I want to see what app I'm switching to. Any ideas what's wrong or what to do?

Hi and welcome...
The app may have not completely downloaded.
Follow the instructions here.
How to Resume Interrupted Downloads

I am trying to get a document from my cloud and on my Mac it says I need an updated version of numbers but when I go to mac app stores it does not allow me to download the new version which I use on my ipad?

I am trying to access a numbers document in mycloud and it keeps saying I need a newer version. I purchased the upgraded app for my ipad and now I can't seem to upgrade my computer so that I can get access. I went to the app store but it won't let me download the newer version onto my computer? What is the point of putting things in the cloud if I can't access them?

Numbers documents from iOS need Numbers 3.2 on a Mac to open. And Numbers 3.2 requires Mavericks. If you are using Mavericks you can get Numbers 3.2 from the Mac App Store. It will be free IF you have Numbers 2 (iWork '09) installed. Otherwise you must buy it.
Your other option is to send the Numbers file as an Excel file via e-mail to yourself to open with an earlier version of Numbers.

Why do I keep getting an unknown error when trying to download an app from the app store on my iPod touch 4th generation when I put in the correct password?

I keep getting the same unknown error has occurred when trying to download an app what is wrong?

as an example.. from the sprint forum for a different device (unsure what device.. it's just not an iphone since no iphone or ios device has these settings -- ive seen this advice several times and I believe it's some form of android.. but not sure)
advice from the carrier advisor --
"Clear data in the Dialer and Dialer storage.... under manage Applications> All.
That is Settings - Applications - Choose All to view All choices - then find Dialer and clear the Data. Repeat this for the Dialer Storage as well. I personally also deleted the message thread first from the text message window and my log history which is a menu item from your call screen."
and another for you from a customer -- it is sprint again.. but this time a Samsung Epic
"OMG ... if someone can't tell me how to fix this "9230: Message sent using invalid number of digits..." error, I'm going to scream. My husband and I both have Sprint Epic phones and love them EXCEPT for this one problem! Help!"
Maybe they should sue Samsung?

Upgraded to OS X 10.9.4 and Safari 'is no longer supported' Also get the error when trying to run the App Store, ' PowerPC applications are no longer supported. This is on a MAC Book Air, purchased in late 2013.

Safari and the App store icons are both deactivated. I also cannot a software update check, as it gives the 'PowerPC applications are no longer supported error'
Very frustrating, cannot do anything with this laptop now. Any help is greatly appreciated.

If you don't already have a current backup, back up all data. There are ways to back up a computer that isn't fully functional. Ask if you need guidance. You can skip this step if you don't care about the data that hasn't been backed up.
Reinstall the OS.* Your data should be unaffected unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault startup volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main Recovery screen.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.9 ("Mavericks"), but the procedure is the same for OS X 10.7 ("Lion") and later.

Problems signing into the Mac App Store?

The App Store shows I have 2 updates to software that I recently purchased (Final Cut Pro and Motion). When I click on the updates I am prompted to sign in... when I enter my login information I keep getting the error message - "There was an error in the App Store. Please try again later. (13)"
Any suggestions?

If you have FruitMenu installed, here is a workaround: First, put your Apple ID into the clipboard (by typing it into any text field and using the Copy command). Second, in the "Enter password" window, triple-click on the Apple ID field, which should open a menu that allows you to Paste in your Apple ID from the clipboard. Now, put your Password into the clipboard, triple-click on the Password field and Paste your Password into the field. You should then be able to Sign In.

"Unknown error has occurred" in MacBook Air App Store

Hi,
When I try to log onto the App Store from my used MacBook Air, it says "unknown error has occured" and doesn't allow me to move forward. I have read that these typs of issues (I am having problems with logging into the computer with my Apple ID and FaceTime as well) can be fixed once upgrading to Mountain Lion, but I cannot upgrade if I cannot connect to the store.
So, how do I go about entering the store without making an alternate ID?
Thanks!

Hi rob8up,
How long ago did you speak to the techs? Have you given them (meaning Apple) enough time to rectify this issue? If not, chill out. If so, then we can't help you here. We are just users like you....
You can send feedback to Apple via this link:

Never Given Option To Sign In To Mac App Store

MBP i7, OS X 10.6.6 (obviously), never restored.
App Store will launch, I can browse, I can goto CREATE ACCOUNT, but clicking sign in from the menus and from the "purchases" tab does nothing (e.g. I click but not even an error message, nothing outputted to console, even).
Anyone else having issues? Have repaired permissions, rebooted, etc, etc. Feels like I'm using Windows .

Sure -
I didn't feel comfortable throwing instructions, if mis typed/done improperly may trash system files (like an improperly positioned asterisk, etc on some below commands could delete more than you should, etc, etc), so I figured it would self-select the people who could/should figure out from the high-level hints what to do from those that would probably be best NOT doing this.
You'd have to try REALLY hard or be incredibly unlucky to have something bad happen out of these sequence of commands, but hey, I'm continually amazed by Murphy's Law....
But who am I to decide who should and shouldn't be messing with their system, so at your own risk (e.g. I will be happy to help if this doesn't work/breaks something, but only have so much time to dedicate and may randomly disappear back to my work at any moment for any, even indefinite, periods of time)...so with that warning, it's actually pretty straightforward and innocent.
1. Download the official installer (do not use software update) - http://support.apple.com/kb/DL1343
2. Download UnPkg - http://github.com/downloads/timdoug/unpkg/unpkg-4.5.zip
3. Double click both files you've downloaded
4. Launch UnPkg
5. Drag the Installer on the Installer Disk Image that is now mounted onto the UnPkg window that says "drag files here" (something like that).
6. It will extract the contents of the update to your disk so you can pull the framework out of there manually and force copy it, apparently the bug is that Apple's installer may not copy it in some circumstances
7. Open a Finder window, goto Applications, goto the Utilities folder, and start Terminal
8. Type and press enter at the end (without the quotes) sudo rm -fr /System/Library/PrivateFrameworks/CommerceKit*
9. Enter your login password when prompted
10. type and press enter at the end (without the quotes) sudo cp -R ~/Desktop/MacOSXUpd10.6.6/System/Library/PrivateFrameworks/CommerceKit.framewor k /System/Library/PrivateFrameworks/
11. Quit App Store (it if is still open)
12. Open App Store, you should be able to login now.

I can't sign into the Mac App Store any more. Can anyone help?

When I click on Sign In nothing happens. App Stores on my other devices are working fine.
This is the first time I've used the discussion forums so I hope I am going about this in the right way.

Welcome to the Apple Support Communities, JohnPaul2!
Try restarting the App Store. Just quit it and open it back up again and try it again. Then try purchasing a free app and sign in there.
Of course, you can also try the well-known "restart your computer" trick. Worked for me a month ago when this happened to me.
