Click the lock to make changes is not working. Lion 10.7.2

Wow. I just looked this up on the web like 30 seconds ago. Boom. SAME problem. I click the button and it flickers for a second and does not work. Cannot create admin via terminal?

OK so a repair permissions and then a full power down and power up worked for me.

Launch the Console application by entering the first few letters of its name into a Spotlight search, and select "system.log" from the file list. Click the "Clear Display" icon in the toolbar. Try to unlock a preference pane. Post any messages that appear -- the text, please, not a screenshot. Do the same with this log, further down in the list: /var/log/secure.log.

award points? : )

I had the same issue. Here are the messages.

Hello.

I have the same problem.

I did what you asked Linc Davis.

There is nothing new on the logs when i click the unlock button.

Do you have anything else in mind?

Thanks

Best Regards

Joao Taborda

i have the same issue,

summary : at mine clicking the lock at any kind of program does not work at all, not working in system pref,

not working at ''get info'' window, not working in any other kind of lock, i tried defragging via idefrag but that couldn't work because it needed a lock to be opened as well, i can't move my files to some folders, getting the ''The operation can’t be completed because an unexpected error occurred (error code 100022).''

plus when i log out, cannot log in because when i type my password it accepts it but then nothing happens, i had a root account as well but i can't enter it and can't create again because of the lock, but when i log in with guest account(no pass required) i can make changes via clicking the lock and filling in admin username and password in system preferences. and i created a new admin account in guest account by filling admin info for authorization in system preferences > users&groups , set no password, logged out but could not log into that account as well. my system is set to login to my account when the system starts.

so this is what i get with the clean display in console, opening system pref, then clicking users&groups, then clicking the lock. this is system.log

i tried repairing disk, permissions, both in system and recovery volume, and i just upgraded to 10.7.4, but the problem was present in 10.7.3, i noticed it two days ago and i just upgraded hoping that would solve the problem.

edit: i have found out that my problem is best described here, not the real concern of the OP but at the 4th option they say its a netinfo database problem, and diagnostics are the same problems that occur to me of that option but the system they're talking about is 10.1.5, i guess things have changed since then, but the problem is the same . http://macosx.com/forums/mac-os-x-system-mac-software/20630-cant-click-click-loc k-make-changes-button-when-installing.html

hope you can help

thanks in advance

Had the same issue on MBP Retina 15", OS 10.8.2.

After restart, issue resolved.

Question is how the **** in the first place has this happened? Never had this on Windows Vista or Windows 7, neither had to restart them to fix something similar.

1) Quit System Preferences

2) sudo killall -9 securityd

3) reopen System Preferences

@ RaceCondition: worked!

It's been 5+ years, and this issue is not resolved. Where is the fix? Hire me.

Looks like this is pretty popular.

I just upgraded to El Cap 10.11 and now both my new iMac and old MacBook Pro refuse any password to unlock the lock to make changes.

i changed my password and it worked.

try to Remove your password (change your password > enter old password > press ok) then change it back.

i hope it works because it's really annoying.
