Problem
Since April 2012, one user of my MacBook Pro can no longer load the Security & Privacy pane.
When I click the icon, a sheet drops down:
Translated from Chinese to English:
Error
Cannot load System Preferences pane "Security & Privacy".
This is chaotic for me. Please: what has happened, and how can I fix it?
I also posted to Apple Support Communities:
Environment
Lion, Mac OS X 10.7 -> 10.7.1 -> 10.7.2 -> 10.7.3 (Build 11D50b).
I setup two users:
- zoomq — my own account
- wan — my wife's account, not often used by her
- zh-CN (PRC Chinese) (Mainland China, simplified characters) preferred for both users
- both are administrators
- install/uninstall software is all standard steps.
Troubleshooting
User zoomq can not load the pane.
Switch users, wan can open the pane without problem.
All other preference panes open and work fine.
When the problem occurs, nothing is logged. I have tried tail -f
and all kinds of /var/log .log files.
I have not touched many system files.
I try remove
/Users/zoomq/Library/Preferences/com.apple.se*
com.apple.security.plist
com.apple.security.revocation.plist
com.apple.security.revocation.plist.lockfile
and rebooted, nothing changed.
$ ls /Library/Preferences/com.apple.se*
com.apple.security.appsandbox.plist
com.apple.security.plist
com.apple.security.systemidentities.plist
com.apple.servermgrd.plist
For wan, ~/Library/Preferences/
com.apple.security.* files are not present.
Best Answer
Try applying a combo update
You might try:
Background
At OS X Lion Update 10.7.3 (Client Combo) there is no hint that Apple published different downloads with identical names. Differences between 11D50b, 11D50c and 11D50d are not published by Apple. This situation surrounding 10.7.3 is most unusual.
Generally, without focus on 10.7.3: in some problem situations, people find that installation or re-installation using a combo has a positive effect.
In this case: the b in your current installation, 11D50b, probably indicates that a combo (combination) update has been applied once already — maybe through the Software Update routines that are integral to OS X. Reapplying the same update, or a more recent build of the same update, should do no harm.
There may be more technical ways of investigating causes of your problem. However: because the symptoms are unusual, I am inclined to suggest a combo update before anything else.
