Unable to update to 10.8.2

Verify the OS you are running. Apple in the menu>About This Mac. What version?

Where did you get this version of Mountain Lion? Looks like a developer build. If so you'll need to purchase Mountain Lion.

TIf it was from the Official Up to date program then nMt Lion should be in your purchases area at the Mac App Store. Try Re-Downloading the full version of OS X and installing that.

If you still get an error during the install then you may have to resize the partition OS X is installed on. There is a Bug that causes installs of OS X and updates to fail. Slightly resizing the partition, only about 100MB to a couple of GBs, somehow allows the installs to work.

How do you resize the partition?

Hi there

I have bought a new macbook pro last week that came with 10.8.1 and I have exactly the same problem:

- iPhoto needs OSX 10.8.2 to update itself

- No software update in my appstore account

- Downloaded several times 10.8.2 update ("normal" and combo)

And when I start installing it says it is not possible to install the update in any volume.

I phoned Apple Support (twice) and tried everything they told me:

- Cleaned the system cache

- Downloaded again

- Created another administrator user account

- Reinstall the entire OS

And now tried the partitioning of the disk as Shootist007suggested

But without any success.

Any more suggestions?

I have only one other suggestion. Return that system for a full refund. You have 14 days from date of purchase to return it for a full refund No Questions Asked.

Then decide if you want to buy another Mac or something else.

I bought it on a "Black Friday" deal. The reimbursement would't be enough to buy a new one and I don't even consider switching to a PC.

I will wait a few more days and try to find a way to update.

If it is not possible, then I will trade it for an exact same model.

I have exactly the same problem.

Bought a Macbook Pro 13", successfully updated to 10.8.2, but there was dead pixel on my screen, so i returned it. Apple sent me a replacement, couldnt install 10.8.2, called apple tech line, tried everyway they told me, till they asked me to ask for another replacement. Now, I'm having a go at the 3rd macbook...

No luck in updating to 10.8.2 !! What's happening??

I contacted Apple by phone and this guy gave me the following explanation:

Macbook Pro Retina 13.3" and iMac 21.5" were released after the 10.8.2 update and thus no drivers were included for these new hardware releases. The first users that updated their new systems with the previous update complainted about problems with keychain. This is why they replaced with a new update that won't appear as updateable in these models, and if you download it the disk won't be valid for installation. Soon there will be a new update available that will correct these issues.

Would it be so hard fo Apple to post this info somewere???

If its a known problem, why didnt the tech helpline inform me. Instead they ask me to do a replacement coz they say it might be harddisk volume issue. Oh well.. I just hope the updates will be available soon..

Thanks for the info ARamoa

Same info from Apple Support in France.... after team asked me to uninstall / reinstall the OS...

Would it be so hard fo Apple to post this info somewere???.... Or inform the teams in Apple Stores....
