10.6.8 upgrade killed my iMac

I have a late 2009 27 inch iMac. Following upgrade to 10.6.8 machine worked ok at first. I went away for a few hours and when I returned could not log back in (my password was not accepted). Finally turned machine off with the on/off button, but since then, despite repeated attempts I can't reboot. Have tried holding "C" down to boot from Snow Leopard install disk and tried booting in safe mode too. No luck. In fact, I don't get starting chime at all. I was getting the Apple logo and spinning disk (forever) but having disconnected my external drive and all other usb devices now I get only a blank screen. Biggest frustration I have had in over twenty years of owning Macs. Thoughts on how to fix very welcome.

Same here. Add to that it ate ALL my mail, including accounts, rules and settings. As if I started mail for the first time, it asked me to help configuring my first account!

How do you solve this?

Manually added all accounts again. Works fine now and I didn't lose important things because my main account is exchange...

You had the same problem?

10.6.8 caused problems with a 2010 update 27" iMac at work today. The performance slowed or would hang for minutes. Reboot outside of safe mode would only get to blue screen and hang. Usual remedies and senior level AppleCare efforts did not yield good results. Reverted to 10.6.7 Time Machine backup from just prior to update. All back to normal. No hardware or disk issues found. Will not update until the engineers fix some bugs. No problems with 10.6.8 on MBP or MacMini however.

Well to update my post from before the holiday. I spent about 3 days messing around with this update after it completely killed my iMac (blue screen, 10-20 min boots, safe mode fails, time machine restore fails, etc). Finally, I did have to resort to a wipe of the drive, reinstall from scratch SL, and re- install the apps needed. I am still getting my things in order, I.E. pics, movies etc; but iTunes was my first priority as it is the homes media server for everything.

I must concur with many; this has been my only dismal experience with an operating system update. Very very unfortunate to say the least. Ruined my weekend when it happened.

My solution was to change my Gmail settings online to IMAP, create those 3 accounts in Mail, disabling the POP accounts for the time being.

Oh, yeah, on Gmail I marked everything I wanted as Unread and moved to Inbox. It was either that or pore thru backups.

Still a total and complete mystery. I updated my old MB Pro 2 weeks later, and guess what.
