10.7.5 on a late 2009 MacBook Pro crashes Ever since I installed Lion on my late 2009 MacBook Pro, it crashes several times a day randomly during some operation (open an application, browse the net, add photos, etc.). 

I read the answer about updating Show Crash Prefs in System Preferences and tried to do it, but it doesn't work. 

I updated Info.plist file with text editor exactly as in the answer, but the Finder still doesn't give the option of selecting new Show Crash Prefs? 

Am I missing something?
Try the following two troubleshooting techniques:


download the latest Combo updater for your OS (note this is different than simply going to the Apple menu > Software Update) and reboot

Then report back.
