Apple Combo Updater

If you are troubleshooting, applying the Apple combo updater might help with your MS Office application problems. Running the combo updater overwrites potentially problem-causing files. Several users have reported this fixed some odd problems they were having.

New to Lion and newer is Recovery Drive. More info

For current OS X, you can get the latest combo updater on Apple's download page. https://support.apple.com/downloads/macos

Apple updates available from the Software Update application are incremental updates. Delta updates are also incremental updates and are available from Apple Downloads (software updates are generally smaller than delta updates). The Combo updates contain all incremental updates and will update files that could have become corrupted.

Combo updaters will install on the same version as they're applying--no need to roll back or do a clean install. So if you think you've got a borked 10.6.6 install from a regular update, just run the 10.6.8 Combo Updater on that system.

"Delta" updaters can only take you from one version to the next. For example: 10.8.4 to 10.8.5. If somehow the 10.8.4 is missing something it should have, and that something isn't changed between 10.8.4 and 10.8.5 it will still be stale after the delta update.

  1. Run Repair Permissions before any Apple update
  2. Use Apple's Disk Utiltiy to Repair or Verify your drive
  3. Restart after running update

If running the Apple combo updater and installing (then updating) Office after using "Remove Office", does not work, then the user should do an Archive & Install of the OS. Lion 10.7.0 and newer should use the Recovery Drive to reinstall OSX.

Snow Leopard and newer now allows you to install over your current install like the "Archive & Install". Insert your Snow Leopard DVD and select to install. It will take you back to the version of the DVD. 10.6.0 or 10.6.x. You would then need to run the combo to update. This does not erase your files, however, it's always advised to backup before any procedure like this.

Even the re-install of Snow Leopard will fail for a few users. Then you need to do an "Erase & Install".

Caution: Before any update, users should backup everything. For Office, an easy way to do this is to stuff a copy of the Office folder. To be doubly safe, stuff your Entourage Identity folder located in the ~/Documents/Microsoft User Data folder. Installs and Updates are not supposed to touch your data, but in rare circumstances it can happen.

User Recommended third party software used to revert to pre-update state:
