Apple updated OS X to version 10.7.3 today, which fixed a number of minor issues — but caused many big ones with some users. If you’re finding that apps are crashing as soon as you launch them, here’s how to fix it.

This bug isn’t affecting everyone, but it has affected a large number of users. Essentially, if you updated via Software Update — as most of us do — you might have found that every app you launch crashes, prompting a very weird dialog box with buttons reading “CUI CUI CUI”. Apple is yet to make a comment on the issue, but if you’ve been afflicted, Macworld offers this somewhat difficult solution:

The combo updater — the version that could also update older versions of Lion — seems to resolve the issue for afflicted users. The problem, however, is that getting the installer to run can be a bit of an issue, if your Web browser crashes each time you try to download it.

Writes Scrace, “I have since fixed the issue by starting my computer up in FireWire Target mode and connecting it to another MacBook Pro.” To launch target disk mode, hold down the T key when your problematic Mac boots up. Download the Combo Updater from a different, working Mac, and then install it to the troubled Mac over FireWire.

If you don’t have another Mac handy, 9 to 5 Mac has an alternative solution, though it involves some Terminal work and other advanced techniques. If you haven’t updated to 10.7.3 yet, you’ll probably want to use the combo updater just to be on the safe side, instead of updating through Software Update. Hit the link to read more.

Some 10.7.3 Users Encounter Nasty Bug; Fix Available [Macworld]


  • I installed it by Software Update and haven’t had any issues. All my apps are launching fine, it even re-opened everything that was open when I began the install.

    Just works

  • Do they even bother to TEST these things before kicking them out to door to customers… ?!?!?! Seriously… presumably many “smart” highly paid people have been working on updates like these for many months totalling 1000’s of human hours… Yet the day it goes public to real-world customers suddenly these errors start appearing ?!?!? Who is in charge of Quality Control for Software at Apple ?

  • Also on 10.7.3, updated through the standard Software Update with not a single problem. In fact, when I updated not only did it re-open everything I had open app wise, it re-opened all the documents I had open, restoring undo state.

    It really does “just work”.

    This makes it seem like only certain firmware/software setups are effected, which could mean that even with normal thorough testing the bugs wouldn’t show up at all.

  • I got bitten by this. Fortunately, I had a time machine backup to restore, then applied the update via the combo updater. Mucho exasperation.

    Rather annoyed but these things happen. Normally I only have to deal with this kind of thing at work in our Windows environment!
