Permissions Differ on Applications/iBooks.app

Question

Hi I recently restarted my MacBook Pro mid 2012 with mavericks installed and was stuck on the start up loading screen.
I restarted on the recovery drive and did disk utility.
After verifying the disk permissions I came across a number of problems that are all relating to iBooks.app - examples;
permissions differ on "applications/iBooks.app/contents/plugins/BKAssetEpub.bundle/contents/resources /cs.lproj/BKEpubAppearanceViewController.strings"; should be -rw-r--r-- they are -rw-rw-r--
Group differs on "applications/iBooks.app/contents/plugins/BKAssetEpub.bundle/contents/resources /cs.lproj/localizable.strings"; should b 0; group is 80
There is a lot of these errors that have come up. What caused this and what can I do to make sure this doesn't happen again?

Hi sdhammond,
Welcome to the Support Communities!
The first thing I would suggest is to repair permissions for the iBooks app on your Macbook Pro. 
Troubleshooting permissions issues in Mac OS X

This is a summary of the information provided in this article specific to your situation:
Using the Finder application, open the Applications folder
Right Click or Control Click on the iBooks app.
Choose "Get Info" from the contextual menu.
Look at the Sharing & Permissions section of this window.
(You may need to click on the padlock icon and type in your computer administrator password).
Under Administrators in the Sharing & Permissions section, you should see your name.
Change permissions to Read & Write for account.
Click OK
If repairing permissions does not resolve your issue, here's how to delete the iBooks app and reinstall it from the Mac App Store:

Open the Finder.
Choose Applications from the Go menu.
Locate your app in the Applications folder.
Delete the app that will not open (drag iBooks to the trashcan icon on the dock).
Open the Mac App Store.
Ensure that you are logged in to the Mac App Store with the same account that purchased the app.
Select the Purchases view from the top of the Mac App Store window.
Find the app and click the Install button beside it.
The app will be installed on the Mac you are using.
Cheers,
