Strangely, installer says that the update failed just before finishing, but then I have a working install of 10.8.3 after reboot (did the same thing when I updated to 10.8.2)
Use myHack to remove problematic kexts
Enable TRIM support (for SSD users: http://digitaldj.net...abler-for-lion/)
All working well.
Nice to have a problem free update.
