In OS X 10.8, for system updates that were installed without being signed into an Apple ID, how can I view the update history?

I looked in Library/Logs for an update log, and also in the Software Update for an Installed Software pane, but I don't have either.

Where can I see the updates?

It can be found in an easy to read format using the system information app:

System Information.app > Software > Installations

System information can be found in /Applications/Utilities/System Information.app or via Spotlight.

  • /Library/Receipts/InstallHistory.plist is it, it is just an xml file which is very easy to read if you have vim or an xml editor installed.

It is not easy to read, but it appears to be up to date on my machine. You can find the Install history in: /Library/Receipts/InstallHistory.plist

Wouldn't it be nice it this were listed in the Update tab of the Mac App Store?

  • Well done - I've been looking for that file and you saved me from trolling spotlight to find it. Now I might need to write a little app to parse that XML file if someone hasn't done that already.

  • @bmike, the answer that Deesbek gave looks like it is just reading that file, although the answer could be a bit clearer.

  • Yes - that appears to be a decent enough app to present the data. Wohoo!

  • most decent text editors like vim will parse the xml for you @bmike, then it is just a matter of collapsing and expanding what you need.

  • @Deesbek, AFAIK vim doesn't parse XML, it just displays it raw. I wouldn't be surprised it EMACS has a mode to parse the XML.

  • Why does some of the logs in /private not appear in /Library

  • The log rotates. Did you also check in install.log.0.bz2 and its successors install.log.1.bz2…?
