Mac OSX Lion 10.7.3 Update Broke My Macbook

I’ve never had a problem using Apple’s automatic updates before and i’m surprised this got passed their testing team. I don’t think this issue affects all macs, but my Late 2011 13″ Macbook was pretty much crippled by the update. I used automatic updates to install the 10.7.3 update from 10.7.2 and upon reboot was greeted by the CUI CUI CUI glitch:

There are tonnes of posts about this issue in the Apple support forums and other various news-related sites. Thankfully by installing the stand alone 10.7.3 Combo Update the issue is fixed… One problem though, I couldn’t even open a Finder or Terminal window to even try to install the combo update!

Most of the posts out there recommend either:

  1. Booting into safe mode (by holding shift during boot), this didn’t help me as I still couldn’t open anything.
  2. Plugging in a USB device with a recovery Lion partition, or connecting another Mac (via Firewire or Thunderbolt) and booting into target disk mode. Not an option, as I didn’t have a recovery Lion USB device or a Firewire / Thunderbolt cable
  3. Restore from Time Machine. Sure, I could have gone into work, picked up my Time Machine drive and restored, but this would have taken at least 4 – 5 hours.

Instead, I tried a different approach! I downloaded the 10.7.3 Combo Update and saved it to plain old USB stick (on another computer of course). I then booted into recovery mode (Command-r at boot) and plugged in the USB stick.

In hindsight, I could probably have just downloaded the combo update in recovery mode using Safari (the browse for help option).

Recovery mode allows you to open a terminal window (Under the Utilities menu) and from here I was able to mount the combo update disk image using

hdiutil attach /Volumes/USB\ Key/MacOSXUpdCombo10.7.3.dmg

I then installed the update, specifying my Macbook’s hdd

installer -pkg /Volumes/Mac\ OS\ X\ 10.7.3\ Update\ Combo/MacOSXUpdCombo10.7.3.pkg -target /Volumes/Macintosh\ HD

This took a good 10 – 15 Minutes, but once it finished (returned to the bash prompt), I rebooted and all was good again! Phew.
