Apple Investigating Mac OS X 10.7.3 Application Crashing Issues

Apple Investigating Mac OS X 10.7.3 Application Crashing Issues

Following the recent Mac OS X 10.7.3 update released by Apple, users have been reporting applications crashing, with “CUI” being stamped on the error messages (as shown below). Apple has already launched an investigation, sending an email out to a Mac OS X 10.7.3 test group, 9to5Mac reports.

Apple’s statement in the email read:

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. If you have encountered this issue please submit a bug report. Be sure to include the following with your report: Install logs, system logs, a full System Report.

There has been no timeframe set for the fix, no any indications as to how Apple plans to do it, however 9to5Mac has found a way to workaround the issue. Try this at your own risk as I haven’t tested it myself.

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 http://support.apple.com/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.

    I was on the phone about 45 minutes. tried to do a disk repairs once. and rebooting from a previous version. cause I had this same problem. what seems to have worked for me is going a hard shutdown, start up holding command R I think it was, and reinstalling from the last version of lion. Because i couldn’t even get “about my mac” or Time Machine to work at all. I had a similar widow pop up for the same programs, but instead of the missing ui graphics they were back for the buttons, rather than the above missing graphics. and reopening the app worked as well rather than pulling up the crash report widow with the same missing button graphics displaying CUI. I went through one by one, starting with, crap now i can’t remember if i opened iTunes first, and updated it, no it was safari that i updated first, the i opened iTunes and it updated itself. 7.3 seems to be working just fine as of now. I left a lot of stuff out because the technician had to refer me to a head manager who, after telling me how long it would take to reinstall lion walked me through the rest. which the computer ended up doing, because I was busy doing something else and heard the reboot chime twice. Hope this helps anybody with the problem

    I had my Mac Pro crash this morning promptly after the update.  I have a Lion recovery USB Thumb drive so I was able to reboot to that and then restore the drive from my Time Machine drive updated a few days ago.  I was really irked by it and fired off an email to Mr. Cook.  It ain’t working.  Tanja

    My Early 2011 MBP had this happen, but my late 2009 iMac was fine. I used Lion internet recovery, reinstalled the OS and was back up and running in about 90 minutes.

    This happened to my 2010 17 MBP but not my 2011 13 MBP.  The solution for me was boot to the recovery partition and reinstall Lion over the existing partition.  It didn’t delete any of my settings, data, or applications, but it did download and install the 10.7.3 version of Lion and my mac works fine now.
