Why does my 10.8.5 OS X not recognize my iPod when I plug it in?
Did you tried Disk Utility->Repair Permissions ??

To remove iTunes and Apple Mobile Device Service(http://support.apple.com/kb/HT1747) in 10.8 and 10.9, Open Terminal (/Applications/Utilities/Terminal.app) and run these commands (substitute &lt;account name&gt; with your mac login username - you need to be Admin user to run these commands; enter your login password when prompted):

$ sudo mv /Applications/iTunes.app /Users/&lt;account name&gt;/.Trash/ 

$ sudo mv /System/Library/Extensions/AppleMobileDevice.kext /Users/&lt;account name&gt;/.Trash/

$ sudo mv /Library/Receipts/AppleMobileDeviceSupport.pkg /Users/&lt;account name&gt;/.Trash/ 

You can then re-install iTunes and try.
