Why is russian beta testing software on my Mac? Yesterday I discovered that there is a piece of software called "Ассистент обратной связи" in the /System/Library/CoreServices/Applications Directory of my Mac (OS X Mavericks). What's the deal with this application? Is is legit? Why does it have a Russian title?
It looks like Feedback Assistant.app. Maybe it's missing the en translations. You can check if that really is the correct app in Terminal with: 

ls /System/Library/CoreServices/Applications


The output will reveal the real (not translated) applications names. 

The Ассистент обратной связи string could be found using:

plutil -p Feedback\ Assistant.app/Contents/Resources/ru.lproj/InfoPlist.strings 


The output:


  {
    "CFBundleDisplayName" =&gt; "Ассистент обратной связи"
    "CFBundleName" =&gt; "Ассистент обратной связи"
  }


To make sure, the app is really from Apple you can run

codesign -d -vvv Feedback\ Assistant.app


and look for Authority=Apple Code Signing Certification Authority.
