I am using Mid-2010 13″ MacBookPro. When the new Lion update 10.7.3 released, without any doubt I straight away installed the update, without doing my backup to TimeMachine… after the reboot, the boot process looks OK, until I try to check the “About This Mac” to verify the version… it crashed and bring me back to the login screen.. sadly all the other apps too… the MacBookPro was hit by the “10.7.3 CUI error” !

Did a Google on “10.7.3 CUI error fix”, I found this very informative website: http://9to5mac.com/2012/02/02/heres-the-fix-for-intermittent-cui-errors-following-the-10-7-3-update/, just my problem is, I didn’t have the latest TimeMachine backup and I do not want to lose my 5-days work (I was outstation and the TimeMachine disk was not with me).

I was planning to follow the guide from the website on using the Lion recovery USB and applying the MacOSXUpdCombo10.7.3.dmg Combo Update.

From the website:

If all fails, the last resort involves booting into a Lion Recovery partition on a boot volume or USB stick:

– Boot into the Recovery partition by holding down the Option key at startup.
– Choose “Disk Utility” from the Menu bar and mount the combo installer image file?.
– Choose “Terminal” from the Menu bar and run “installer -pkg /Volumes/Mac\ OS\ X\ 10.7.3\ Update\ Combo/MacOSXUpdCombo10.7.3.pkg -target /Volumes/Macintosh\ HD” (Change the target to reflect the startup volume’s name.) Be patient, as it can take up to 15 minutes or more to apply the combo update.
– Run “reboot” and you are done.

DISCLAIMER: This procedure works fine for my MBP case, it might not be the same to all other user. This is just to show the steps that I follow to get the 10.7.3 update works on y MBP.

So, firstly I downloaded the 10.7.3 ComboUpdate around 1.2GB (using my PC.. yes it’s running Win7pro), once done I transferred it into my USB drive.

Then, I plugged-in the Lion USB Recovery drive and also the other USB-drive with the 10.7.3 ComboUpdate into the MBP (MacBookPro). Restart the MBP and go into the “Recovery Mode” by holding down the “Alt/Option” key when booting up.

The first screen asked me to choose between the 2 USB drive that I plugged-in, so I chooses the Lion-Recovery USB drive. The MBP then boot into the Recovery Mode. Select the “Disk Utility” to verify that both the USB is mounted and the BootDisk is mounted. Then I close the “Disk Utility” to go back to the main screen.

From the MainScreen, I open the “Terminal” from “Menu” -> “Utilities”.

Then, in the terminal, I can’t execute the “installer” command from the website earlier, because the ComboUpdate that I have is in “.DMG” format, I need to get the “.PKG” file which is inside the “.DMG” file. First I copy the ComboUpdate from USB-drive (/Volumes/MR2) into my boot HardDisk (/Volumes/MR.OMAR).


cd /Volumes/MR.OMAR/users/user1
cp /Volumes/MR2/MacOSXUpdCombo10.7.3.dmg .

To get the “.pkg” ComboUpdate from the “.dmg”, first you need to “mount” the “.dmg” file using the “Disk Utility” tools. So, I quit from Terminal. In the MainScreen, I select “Disk Utility” again, and select from the “Menu” -> “File” -> “Open Disk Image”.

Then I browse the boot HardDisk to open the DiskImage “MacOSXUpdCombo10.7.3.dmg” and to mount it.

Once mounted, the DiskUtility will looks like this:

Then I quit from the DiskUtility to go to the MainScreen. In the MainScreen I select the “Terminal” (Menu->Utilities->Terminal) again. I then go to the mounted DiskImage of the ComboUpdate and copied it into my boot HardDisk (/Volumes/MR.OMAR), under my users folder – just in case, I changed the ownership of the “.pkg” file to my user too (uid=501) and return back to the main location (using “cd”).


cd /Volumes/Mac\ OS\ X\ 10.7.3\ Update\ Combo/
-bash-3.2# ls -la
total 2609520
drwxr-xr-x 3 root wheel 170 Jan 21 00:21 .

-bash-3.2# cp MacOSXUpdCombo10.7.3.pkg /Volumes/MR.OMAR/Users/user1/
-bash-3.2# cd /Volumes/MR.OMAR/users/user1/
-bash-3.2# ls -la MacOSX*
-rwxr-xr-x@ 1 501 staff 1357366447 Feb 4 00:58 MacOSXUpdCombo10.7.3.dmg
-rw-r--r-- 1 root staff 1336072999 Feb 4 01:05 MacOSXUpdCombo10.7.3.pkg

-bash-3.2# chown 501 MacOSXUpdCombo10.7.3.pkg
-bash-3.2# ls -al *.pkg
-rw-r--r-- 1 501 staff 1336072999 Feb 4 01:05 MacOSXUpdCombo10.7.3.pkg
-bash-3.2#
-bash-3.2# cd

Now that I have the “.pkg” file of the ComboUpdate, I’m now ready to run the ComboUpdate” on top of the existing 10.7.3 update I ran earlier (which caused the CUI error problem).


-bash-3.2# installer -pkg /Volumes/MR.OMAR/users/user1/MacOSXUpdCombo10.7.3.pkg -target /Volumes/MR.OMAR
installer: Package name is Mac OS X Update Combined
installer: Upgrading at base path /Volumes/MR.OMAR

installer: The upgrade was successful.
-bash-3.2#

it took a while for the update to run, then I received the “installer: The upgrade was successful.” message (finally)…

After that, I do a “reboot” to restart the MBP.

First thing I did once the MBP fully up was to check the version in “About This Mac”…

That’s it, the update 10.7.3 is now working fine on my Mid-2010 13″ MacBookPro…
