Help with "os x needs to repair library to run applications"!

[Ace_Jocelyn]

Hey guys looking for some help with a major issue I'm having with my iMac. I recently purchased a used iMac and it was working well until I decided to go ahead and start changing the admin name and eventually the "home directory". I probably should not have done that because when I restarted I was hit with a box that said "os x needs to repair library to run applications". I put in my username and password and nothing happens, the box just keeps appearing. I'm at a point now where I can't even open any applications (I'm writing this on a different computer) or even save a screenshot because it says I don't have permission.Also, for some reason I can't right-click... Is there anyway to fix this without losing the installed apps? The preinstalled apps were a huge selling point for me and if they can't be brought back it'd be a fairly big loss for me. That being said, I'd take a loss of the apps if I could just get the computer functioning properly. Any help would be much appreciated.

btw, its a 27" 5k (Mid 2015) iMac running Yosemite 10.10.2

Hello and welcome.

-How did you change the admin name? That isn't recommended, as it can cause problems like you are experiencing.
-Do you have a lot of documents/files in the damaged user's folders that you need to save?

Hi,


You could try this, if you can access your applications folder then terminal.

1) Log in as an administrator

2) Open the Terminal (located in Applications/Utilities)

3) Type: sudo update_prebinding -root / -force and press Return.

4) When prompted for a password, enter your admin password, and press Return again. The process may take a few minutes, and you may see various messages flash by. The process is complete when the Terminal returns to a normal prompt.

5) Type exit and press Return.
