Cannot Update Mountain Lion

I have an iMac 27" 2.7 Quad Core running OS 10.8. The App Store says I have 3 available updates, however none of them are for the latest version of os 10.8. How do I get the latest version of ML from the App Store if it's not showing up on my available updates? I hope that makes sense.

Try Here...

After Updating Mountain Lion, Mail & Safari keep crashing; WLAN Connection fails

After Updating Mountain Lion, Mail & Safari keep crashing; WLAN Connection fails;
I have updatet Mountain Lion and since then, Mail & Safari keep crashing plus: WLAN Connections keeps on failing from time to time.
My Router has the newest firmware, i am clueless what to do.
I even cannot shut down my mac properly.

Hello you all,
I also had the problem of a disconnecting wifi while my imac was sleeping. I did not have the reconnecting issue after sleep, but the lost connection issue during sleep which made it impossible to reach my imac for things like homesharing, apple tv or remote desktop. I have a late 2012 iMac with a clean ML 10.8.2 on it and wirelessly connected to an apple time capsule (same as an airport extreme). My partner has a mid 2007 iMac, also with an ML 10.8.2 on it.
I tried every single solution I could find on the internet, such as changing the router's security from wpa2 to wpa, changing the MTU from automatic to manual 1453, router reboots, re-installations, re-configurations, keychain clean-ups, everything.
Eventually I solved my problem with these steps and now it works as a charm. I can still find the iMac with the remote app, even after 12 hours of sleep:
My time capsule router is set on automatic MTU and encrypted with WPA2 and I use the 5Ghz network!
1. Cleaned all the wifi passwords in keychain on my iMac
2. Created a new network location in system preferences
3. In this location I deleted the bluetooth pan and bluetooth dun connection.
4. In this location I changed the preferred connection-order to wifi on #1 and ethernet on #2.
5. Restarted my iMac.
Now I still have a connection when it sleeps and I can wake it to low profile using the remote app (homesharing) and everything works fine.
Hope more people wille be helped by this.

Updated mountain lion today now can't sign in to access my computer

Updated Mountain Lion today and now cannot sign in to access computer. Changed my password on Apple ID but no luck. Talked to tech, not eligible for tech support. Can someone help......

You say 'sign in to access computer'. Are you talking about the main login screen when you first boot the Mac up? If so then that's completely different to an Apple ID and you need to go about resetting that PW in a different manner.
Apple ID's are used for purchases through the iTunes Store, the Mac App Store and for logging into iCloud.

Lion cannot see mountain lion time machine backups

I have just had the HDD on my 2010 iMac changed under the 1TB replacement program. Before wiping my original HDD I made sure my time machine back was up to date. Originally my machine was installed with Mountain Lion, the new HDD has just Lion. I have just tried the recovery utility to restore using time machine and all it can see is my updates before I installed Mountain Lion. Presumably Lion cannot see Mountain Lion backups or something else. Does anybody know how I can simply get my most upto date time machine backup to restore the system.
Thanks

FYI I updated to Mountain Lion and still cannot do a full recovery from any Mountain Lion backups. The backups exist as I can see them in Finder and also when running the Time Machine app. In the app I'm able to restore individual items, but I don't want to waste my life doing this I just want to restore my system.

How to update mountain lion

i dont know how i update mountain lion. i have osx 10.7.5. i dont know how i get osx 10.8.3?

Welcome to the Apple Support Communities
OS X Mountain Lion is a paid version, so you can't get it from Software Update.
First, make a backup of your data, just in case the upgrade fails. Then, check that your computer is compatible with OS X Mountain Lion > http://www.apple.com/osx/specs If it's compatible, open the App Store and purchase OS X Mountain Lion.
The OS X Mountain Lion installer will be downloaded. It takes 4 GB, so this may take hours. When it finishes, the Mountain Lion installer will show up, so follow the steps to upgrade to Mountain Lion

I get the message"The product distribution file could not be verified. It may be damaged or was not signed." and cannot download mountain lion. what is the probem?

You do meet the hardware requirements. Otherwise you wouldn't have been able to purchase ML.
If you're connected wirelessly to your router, connect with Ethernet.
If you're connecting through a proxy, connect directly.
Boot in safe mode (shift key down at startup) and try again.

HT1338 How can I upgrade to Lion? My iMac cannot support Mountain Lion but I do not see Lion in the app store anymore.

I want to upgrade my 2006imac with 3GB ram but mountain lion requires 4gb. Can I purchase mountain lion in the app store and it will install lion or will it just charge me $20 for an OS I can't use?

A 2006 iMac cannot run Mountain Lion at all. Mountain Lion only requires 2 GB of RAM, but your model has a video controller which doesn't support features required by Mountain Lion, so Mountain Lion does not support your model. The earliest iMac which can run Lion is the mid 2007 model (aluminium body). A full list of supported models is available here.
If you attempt to buy Mountain Lion in the App Store using your 2006 iMac, the sale will not proceed and you will get an error message saying you cannot purchase Mountain Lion because it is not compatible with your computer. You will not be charged.
If you are currently running Snow Leopard and want to upgrade to Lion, but didn't already purchase Lion (e.g. for use on another computer), it is apparently possible to place a special order for Lion via a telephone call to Apple Customer Support. (I say "apparently" because there have been reports that Apple told some people this was the correct solution, but early attempts to place an order were refused with Apple Support claiming they weren't selling Lion at all. I think this was a temporary situation and it should be resolved by now.) There are links to support telephone numbers here.
Apple will charge you the standard retail price for Lion (e.g. US$29.99 in the US) and supply you with a "redeem code" for the App Store. That is entered by going to the Featured category in the toolbar, and clicking Redeem under the Quick Links heading on the right side. Once your code is redeemed, Lion will be added to the list of purchases for your Apple ID, and you can download and install it.
If you had already bought Lion for use on another computer, you can re-download it from the Purchases list in App Store, but there might be a couple of catches:
1. Some people have found that Lion was added to their list of hidden purchases. You need to unhide it first. Do this by going to your Account page (under Quick Links, or "View My Account" under the Store menu in the menu bar). If you have hidden purchases, there will be a "View Hidden Purchases" link, and from there you can unhide Lion.
2. If you are running Lion and want to redownload the installer on that computer, you may need to hold down the Option key when clicking on the Purchases heading in the toolbar, to enable the download button for Lion.

Has your problem been solved by the updates??
Have a similar problem. This MacBook opened all MS Office programs in Dec2012 but no longer does in Feb2013. Went to Microsoft/mac/downloads but none of the three updates would run citing a problem "version of software needed to run this update was not found on this volume".
MacBook: 7.1, Intel Core 2 Duo, 2.4 GHz
Microsoft Office 2011: version 14.2.3
Mountain Lion: 10.8.2 (12C60)
