6 times, I’ve tried to update to 10.5.6 and failed. Each time I learned something new about my system and Leopard in general, but the result still remain, I cannot boot after the update. I still run into the “still waiting for root device” error. I’ve posted to the uphuck.com forum for help and learned that it might have something to do with my SATA hard drives. I’ve tried various boot flags suggested by other people, ie CPUS=1, rd=diskXsY, etc… but to no avail.
Luckily I had the forethought to create a separate partition for time machine to store its backups so its not too much of a hassle to restore my system back to 10.5.5
I’ve found several guide for safe updating to 10.5.6 and tried them all but ultimately none seem to work for me
The guide provided by Vinay Prashar @ http://ihackintosh.blogspot.com/2008/12/update-105x-to-1056.html was particular helpful.
I’ve also found articles regarding the “root device” error. If you’ve run into the same problem, give these articles a read.
Perhaps you will have better luck with the update but as for me its back to the forums.
One particular helpful resource I’ve ran into while looking for answers is the Mac OSX86 search engine provided by PcWiz at http://www.pcwizcomputer.com/osx86search Give it a try if you run into problems during your installation & configurations. Good luck!
