After 10.5.3 update i can't boot up to my desktop

Question

I updated my macbook with 10.5.3 and everything is fine; But, I updated my wife's MacBook and it won't boot up past a light blue screen; it is stuck;
the only difference was she had other updates, as well as Leopard update;
What can i do to get hers to boot up to desktop?

Answer 1

It seems like a cache corruption.
A) If you have another user on the wife's macbook try the following steps.
1) Restart into Safe mode and login as alternative user
2) Download Leopard Cache Cleaner or TinkerTool System or Maintenance or Cocktail
3) Clean the caches, by example with Leopard Cache Cleaner check "Deep Cleaning" and Local, System and All User Caches
4) Reboot
B) If you haven't any other user on wife's macbook (is not a good idea to have only one user on os x)
1) Boot wife's macbook in target mode, and connect it to your macbook
2) and from your administrative user follow the step A 2 and A 3
3) Eject wife's macbook and reboot
C) If you prefer terminal Follow B 1 steps then
1)
/usr/bin/sudo /bin/sh -c "/bin/rm -f /Volumes/Wife's HD name/Library/Caches/com.apple.LaunchServices.";
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/Users//Library/Caches/com.apple.LaunchServices*." ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/Users/*/Library/Caches/.LSApplications_Backup" ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/Users/*/Library/Caches/.LSClaimedTypes_Backup" ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/Users/*/Library/Caches/.LSSchemes_Backup" ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/Users/*/Library/Caches/LSApplications" ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/Users/*/Library/Caches/LSClaimedTypes" ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/Users/*/Library/Caches/LSSchemes" ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/Library/Caches/*" ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/System/Library/Extensions/Caches/*" ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/System/Library/Extensions.mkext" ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/System/Library/Caches/*" ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/private/var/db/BootCache.playlist" ;
/usr/bin/sudo /bin/sh -c "/bin/rm -rf /Volumes/Wife's HD name/Users//Library/Caches/" ;
2) Eject wife's macbook and reboot
