Unable to authenticate myself to make changes in System Preferences or install programs

Question

Hello everyone I am just freaking out because I don&#x27;t want/can&#x27;t reinstall the system!!I just recently started having the problem that every time that I wanna install something, when it should ask me for my password to authenticate my admin account, the window never shows up and the program shows up as "Not responding". The same problem occurs when I try to click on the padlock in the System Preferences to try to make a change it changes from "click the lock to make changes" into "authenticating" but the window never shows up (images below).I am the only user with Admin rights in my Mac OS 10.10.2; MacBook Pro (13-inch, Early 2011), 2.7 GHz Intel Core i7, 10 GB 1333 MHz DDR3, Intel HD Graphics 3000 512 MB.I have tried:- I restarted - no good.- Repair the permissions - no good.- Also tried repairing the keychain access - no good.- In Terminal I tried: sudo killall -9 securityd; sudo pkill -HUP securityd; ssudo killall -HUP securityd - no good (and said that only Apple apps can do that).I checked in the console and this comes up: Marker - 28 Feb 2015, 4:34:54 PMFeb 28 16:35:01 MacBook-Pro.local SecurityAgent[1815]: Critical failure: the LastResort font is unavailable.Feb 28 16:35:01 --- last message repeated 123 times ---Feb 28 16:35:01 MacBook-Pro.local SecurityAgent[1815]: -baselineOffsetFromBottom returned a number that is not integral in pixels.

Hi. Is the reason you don&#x27;t want to reinstall is you do not have a backup? You can still go to the recovery partition and use the utilities to check and repair the disk. I will say that when a reinstall is done from recovery it is not suppose to change you personal files. Only reinstalls the operating system. Use command/R on startup.

Hi my ginger, Thanks for the reply, I did what you recommended and reinstall with Command+R and you were right all my files survived!Unfortunately the situation persist I keep having the same problem and I cannot  authenticate! Still the window to enter my password doesn&#x27;t show and the lock stays saying "authenticating" even after I reinstalled! :-( what could it be? !

Hi. Have you gone to disk utilities and repaired permissions? If that does not work. Try going back to recovery and use the utilities and go to terminal. Type in   resetpassword and hit enter. You should be able to use the same password. See it this solves it.
