How can I remove duplicated items in the install updates list? I just tried to install the OS X 10.10.3 update from the App Store. My internet is slow and after several hours, it finally finished.  It asked to restart, and I accepted.  But nothing happened.  I clicked the "Update" button again, and told it to restart several times, to no avail.

After a few tries, it started the whole download again!!!!

I cancelled it (I'll have to try again tomorrow), but now my Installed Updates list shows this:

And I don't know how to remove all the duplicate entries... or just a good installation of the update!! This is my first Mac, and is a serious negative experience for me... Other OS beta releases aren't this bad!! Any idea on how I can fix it?

EDIT: I was able to install the update with the combo updater, but the repeated updates are still appearing.  Does anyone have any idea what file I can edit to get it listed only once?
Something, somewhere, didn't register correctly.

Possibly someone maybe able to figure out exactly which receipt or App Store file to find, however, it would be far simpler &amp; possibly safer to just get the standalone OS X Yosemite 10.10.3 Combo Updater &amp; run it again; because you don't know what else didn't happen as planned either &amp; the Combo will make sure everything since 10.10.0 is correctly updated.

You can use a download manager to fetch it, too &amp; it will then be resumable if the download halts for any reason.
