I have tried to get updates to install with no such luck.  I have searched the forums for weeks and trying different things.  I will try to give a specific breakdown of what I have not installing and what I have done so far.


Things that will not install:

- iTunes 11.0.1

- AirPort Utility 6.2

- HP Printer Software Update 2.13

- Remote Desktop Client Update 3.6.2


- Mac OS X Mountain Lion


The first four are updates and this is what I have done to try to get them installed:

1.  Install 1 at a time.  This worked for some but these 4 are left.

2.  Download the updates from the website and install.  Still no go.

3.  Delete the current versions from the computer and install them fresh.  iTunes could not be deleted and everything else that was deleted is no longer on my computer so I am unable to print to my HP printer.

4.  I've Verified and Repaired the Disk Permissions and the Disk.

5.  Done an SMC and PRAM reset.

6.  Removed from the preferences folder.  Has not helped at all.

7.  There were a couple of other things but I can't remember what they were.


As far as Mountain Lion, I have done the following or at least tried.

1.  Just download it and save to a portable hard drive.  Have not managed to get the App Store to download it only.  It tries to install and says the same thing as software updates.  "An unexpected error has occurred."

2.  I've seen all the suggestions to go to HD/Applications/Mac OS X installer.  This never even gets installed so basically my computer is not installing anything.


This is basically my last resort before calling Apple and possibly having to spend my life's savings for tech support over the phone since my Apple Care plan just expired.  One last thing I have tried is installing a new app.  I tried XCode since I forgot to reinstall it a while back.  It doesn't install either.

    Have you tried Disk Utility ( Repair Disk ) ??

    If you have more than one user account, these instructions must be carried out as an administrator.

    Launch the Console application in any of the following ways:

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

    Select "/var/log/install.log" from the file list. Then select the messages from the last installation or update attempt, starting from the time when you initiated it. If you're not sure when that was, start over and note the time. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.

    If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.

    When posting a log extract, be selective. Don't post more than is requested.

    Please do not indiscriminately dump thousands of lines from the log into this discussion.


    Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.

    Your OS X installation is corrupt. Back up all data.


    Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.


    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.


    When the OS X Utilities screen appears, follow the prompts to reinstall the OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.

    I have been searching for possible reasons why my Macbook Pro OS X will not install updates and I saw this posting. I have not tried all that swilliams921 has tried, but I am not tech savy, but from reading her post I am thinking that mine is possibly corrupt, as well. How can you verify that for me? And if I run the Repair Disk will I lose information if I am not backed up? Do I need an actual disc that the computer came with, because I don't recall having one, but maybe it is still in the box?


    I have noticed the computer in general wasn't working as quickly or cleanly as it normally does for the past couple months. I just don't want to lose everything again. My Dell did that two years ago and back up drive malfunctioned, which is why I changed to Mac thinking it would last longer than two years!


    Thanks for any help!!

    If you run Recovery OS as Linc says, you will not loose anything, it just "renews" the OS (but ofcourse you have backups!).
