How do I get rid of Genieo from my MacBook Pro?
Is there any way to get rid of Genieo manually?


The only way is to do so manually. Carefully follow Thomas Reed's Genieo Removal Guide to completely rid your machine of the offending adware. Here is an abbreviated version of Thomas Reed's guide:


Quit Genio. Remove /private/etc/launchd.conf. 
If it's not present, move on. If it is, trash it and restart the machine (See the warning in the full guide about overlooking this step). 
Remove the following files, if present:

/Applications/Genieo
/Applications/Uninstall Genieo
/Applications/Uninstall IM Completer.app
~/Library/Application Support/com.genieoinnovation.Installer/
~/Library/Application Support/Genieo/
~/Library/LaunchAgents/com.genieo.completer.download.plist
~/Library/LaunchAgents/com.genieo.completer.update.plist
/Library/LaunchAgents/com.genieoinnovation.macextension.plist
/Library/LaunchAgents/com.genieoinnovation.macextension.client.plist
/Library/LaunchAgents/com.genieo.engine.plist
/Library/LaunchAgents/com.genieo.completer.update.plist
/Library/LaunchDaemons/com.genieoinnovation.macextension.client.plist
/Library/PrivilegedHelperTools/com.genieoinnovation.macextension.client
/usr/lib/libgenkit.dylib
/usr/lib/libgenkitsa.dylib
/usr/lib/libimckit.dylib
/usr/lib/libimckitsa.dylib
Restart the machine again. 
Remove /Library/Frameworks/GenieoExtra.framework and empty the trash.
Remove the Omnibar Extension from your browser. See full guide if you are unsure how to do so. 
Reset the Home Page, and possibly default search engine for your browser.
