I can't install updates on my MacBook (version 10.6.8)

Try just doing 1 update at a time.

I've been having the same problem for months! I've scoured the forums but I haven't seen another post (until now) that was the same situation as mine.

Try downloading the updates individually from Apple's support site and installing them that way. Also, check in System Preferences --> Software Update --> Installed Software and see if they are being installed.

Had the exact same problem until about five minutes ago. I came across this and a few other threads on this topic, found nothing, and poked around with my Software Update window myself.

I went down the list of installed items and saw that I had two updates for iTunes: one was the most recent, version 11.0.0, and a previous, uninstalled update for 10.6.something. I unchecked the box for the out-of-date iTunes, hit install, and it worked perfectly--my computer restarted, opened back up with the grey installation meter, and came back on with everything installed.

I also unchecked the box for the Firmware update, which I had heard was causing some serious problems once installed in some other cases.

Note: As it turns out, one of my 11 updates that previously hadn't been installing was an update for the Software Update function which "addressed an issue that was preventing the Software Update application from installing downloaded updates." Guess that one worked, huh?

Good luck to you.

Reinstall the 10.6.8 Update Combo.

See if that will help out.

I had the same problem. Try unhooking any non apple device, including chargers, from the Mac and try again. That's what I did and it worked!

I had the same problem. When I went through and did one update at a time, I noticed that only the updates with the white triangle inside a gray circle next to them required a restart in order to be installed. I went through the updates one by one, and did the two that needed a restart last. I still did those two one at a time. By doing it this way, everything installed properly.
