A large number of OS X Lion users are experiencing and odd bug that is causing CUI errors and app crashes after updating to 10.7.3.
Those affected claim applications crash with “CUI” stamped all over the error message. Apple is already investigating the matter and has sent the following email out to a OS X 10.7.3 test group.
We would like to know if you have experienced an issue after updating to 10.7.3 characterized by the following: Applications crash or quit on launch, The term “CUI” and other graphic anomalies appear in dialogs and windows.

However, for those already experiencing problems, some have had success booting the affected system in Target Disk Mode by holding down the “T” key during startup. To do this the affected computer will need to be connected to another mac via FireWire or Thunderbolt and run the combo installer on the other Mac against the affected machine’s boot drive.
For some this doesn’t work either, at which point restoring from the most recent Time Machine backup and applying the combo installer would be the easiest solution. However, if that doesn’t work 9to5Mac provides the following instructions:
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.
If you do not have the combo installer at hand, follow these steps after booting into the Recovery partition and before executing Terminal commands:
- Select “Browse for help online” to launch the Safari browser .
- Visit Apple - Support - Downloads and download the 10.7.3 combo update [direct link].
- Quit Safari after the combo installer is successfully downloaded.
- Open Disk Utility from the Menu bar, choose “Open Disk Image” from the File menu and select the combo installer from where you saved it.
- Quit Disk Utility after the volume is mounted and apply the aforementioned Terminal commands.
- 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.
If you do not have the combo installer at hand, follow these steps after booting into the Recovery partition and before executing Terminal commands:
- Select “Browse for help online” to launch the Safari browser .
- Visit Apple - Support - Downloads and download the 10.7.3 combo update [direct link].
