a short diary of some part of my life.

Since I installed Mountain Lion, I experienced duplicated list of apps on the ‘open with’ menu. If you want to clear up all the duplicated apps, type the command below in Terminal:

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