How to customize open with menu in Yosemite? I want to customize the right click/"open with" menu for some file extensions like jpg, in order to see just the 4 apps i want to use with this file type. Google suggests me to edit the info.plist file of the apps (Applications/**/Contents/) by changing the CFBundleTypeExtensions section. This does not seem to work anymore in Yosemite. Does anyone know this?
You need to reset LaunchServices for changes to take effect:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain user;killall Finder
