can't do normal boot up since 10.8.3 update

ever since i updated to 10.8.3 i can no longer do a normal boot up.

when i power up my iMac, it goes to its normal gray screen, the arrow as usual pops into upper left corner then immediatelly turns into the dreaded spinning beach ball. this is where my systems hangs. i have to force shut down my iMac via holding power button. i even have to turn power strip off before attempting a second boot. so far my iMac has successfully started upon second booting attempt.

this has only started and become an issue since 10.8.3 update (3-14-13).

is anyone else experiencing this? any suggestions?

its super aggrevating, not to mention not very good for computer to be on a consistent basis shut down forcefully. thanks for any help.

iMac, OS X Mountain Lion (10.8.3), 16BG RAM

I cannot boot up all the way after a complete shut down without forcing a shutdown. Also must turn power strip off before attempting a second try. It does seem to boot in its entirety on second try, albeit today it decided not to.

I turn off power strip which feeds peripherals and computer at night after I shut everything down.

It's been doing this ever since update..

What is strange is the fact that iMac is running just fine since I downgraded to 10.8.2 . Not sure how my configurations can be causing this new update to cause havoc, yet all previous have never. And I have not done any changes. Also, I noticed after I stalled 10.8.3 lots of changes occurred in system preferences, ie dimming of screen before going to sleep. No screen saver also, the hard disk was set to turn off after an hr....all things which I have not set to that. So am unclear why that happened.

@bucketheadbobby, I don't believe it's possibles to selectively update. In my case, for example, I wouldn't even know what part of the 10.8.3 update caused all the problems.

That said, if you wanted to update say, java only, then you can go straight to their site to do so. Other than that, until Apple comes up with a grand cure for this mishap, may I suggest to just go back to or stick with 10.8.2.


Sorry for not being able to help

well, this is funny (not in a haha way). i was having some RAM issues, hence replaced all. then for kicks and giggles went ahead re-updating my iMac 11,3 to 10.8.3. now the update is working with only one huge problem/issue remaining ( as oppose to nothing but problems and issues): Preview. app is no longer working properly.

yes, i have deleted several times the subfolder in ~/Library/Containers/com.apple.Preview also removed any .plist pertaining to Preview in the Preferences folder. did the permission repair and that good jazz. no changes.

i guess Apple has still many bugs to iron out. hope its done soon, as Preview.app is quite a vital part of my everyday operation.


there is one very interesting thing i saw while using x-slimmer: all apps, logs, utilities, etc are double entered. its like as if 10.8.2 is still there and 10.8.3 is running parallel to it. very odd indeed.

Geez what a nightmare this all is. For me replacing my RAM made a difference in terms of at least getting back in, up and running. But I had suspected RAM to be partially to blame as I had started seeing freeze up more often on my system, 10.8.2 version.

This tells me that the update to 10.8.3 is greedy for RAM . when I stepped back to 10.8.2 leaving the same RAM in place the operating system booted just fine.

After the RAM upgrade all works well system wide except for Preview is no longer responding. The only way around that is to get into the "get info" window and then select via "other" found at bottom of pane. the Preview app. I noticed is ghosted at top of said list.

The update has loads of issues . I also saw that I have all applications, all utilities, etc twice only one is ghosted or grayed out the other normal like it needs to be. All third party apps work fine.


Sorry for long windedness . I had to sometimes force shut down more than 3 or 4 times before it finally booted into 10.8.3

This was my feedback to Apple -


After installing 10.8.3 update my iMac 27" Late 2009 no longer boots up. The OS will however boot up in safe mode.


Formated the hard drive and reinstalled Mac OS Lion and the OS booted up correctly however once again after installing 10.8.3 update the computer would no longer boot properly.


I am hoping you will resolve this glitch for the next OS update.
